Description

P37195NLOO / MBA Title: Tinnitus treatment device FIELD OF THE INVENTION The present invention relates to a tinnitus treatment device for treating cochlear tinnitus, a tinnitus treatment system, and to a method for treating cochlear tinnitus. The invention further relates to a machinereadable instruction for performing the method. BACKGROUND OF THE INVENTION Tinnitus is the perception of sound when no corresponding external sound is present, and may e.g. be caused by hearing damage, noise-induced hearing loss or age-related hearing loss. It has been found that multiple origins of tinnitus can be distinguished. A first type of tinnitus is induced in the brain, e.g. as a phantom pain. Presently, it has been tried to treat this type of tinnitus via a wide range of methods, which aim at influencing brain activity. For example, it has been tried to ask a patient to indicate a specific tinnitus frequency that is perceived, which frequency could then be ltered out from sounds played to a patient via a headset, with the goal of training the brain to ignore the recreated tinnitus sound. In the past, known tinnitus treatments have focused on this cause in the brain. For example, temporary cancellation of a perceived brain-induced tinnitus sound may be achieved by providing an externally generated sound monofrequency sound that is phase-shifted with a tinnitus sound perceived by a patent in order to cancel the perceived tinnitus sound. However, this cancellation only works as long as the externally generated sound is provided, which cannot always be the case. Further, this is only possible for a limited group of tinnitus patients in which monofrequency tinnitus is experienced. However, tinnitus is a complex of issues taking place in the ear, the brain and the body. It has been found that a second type of tinnitus exists, which originates in the cochlea and is caused by partially damaged hair cells. With cochlear tinnitus, the partially damaged hair cells cause an undue trigger of nerves to send signals to the brain and thereby cause a perceived tinnitus sound. At present, no treatments are known that address this second form of tinnitus, as it is hypothesised that damaged hair cells cannot be repaired. In addition, within current ear nose and throat methods, it remains impossible to distinguish between a brain-induced tinnitus and a cochlear tinnitus. Further treatment specically directed to the cause of the second type of tinnitus has therefore been regarded as not possible. Also, tinnitus treatments in the past have always been addressing symptoms, and not the actual cause of a perceived tinnitus sound. Further, known tinnitus remedies require special equipment and / or medical assistance. As the therapy may be only effective for a relatively short period of time, or not effective at all, treatment has been a burden for people experiencing tinnitus, especially of cochlear tinnitus. As a result, treatment of tinnitus has remained relatively inadequate, especially for cochleartinnitus. OBJECT OF THE INVENTION It is therefore an object of the invention to overcome the abovementioned drawbacks, or at least to provide an alternative tinnitus treatment and device therefor, for example a tinnitus treatment that allows treatment of cochlear tinnitus, that allows to address the actual origin of a cochlear tinnitus, that is non-invasive, that can be performed conveniently and / or a tinnitus treatment having effects that last for a relatively longer period of time, e.g. a tinnitus treatment that may even completely turn off the perceived tinnitus sound. DETAILED DESCRIPTION OF THE INVENTION The present invention provides, according to a first aspect, a tinnitus treatment device for treating cochlear tinnitus in a user according to claim 1. The tinnitus treatment device comprises an acoustic source for providing sound to an affected ear of the user; and a control unit operatively connected to the acoustic source for controlling the acoustic source. The acoustic source may for example comprise a speaker or a bone conduction device. The acoustic source may comprise a directional acoustic source arranged to direct the sound to a desired ear. The acoustic source may for example comprise a headphone, e.g. an on-ear or inear headphone. The tinnitus treatment device may comprise a visual indicator for displaying a visual signal to the user, i.e. the patient, and / or an input unit for receiving input to control the visual signal and / or the acoustic source. The visual indicator, the acoustic source and the input unit may be operatively connected to each other. The tinnitus treatment device is arrangeable in a treatment mode. The control unit is configured to, in the treatment mode, determine tinnitus property information representative for at least one origin property of a perceived tinnitus sound, such as an origin frequency. The tinnitus property information may for example be pre-programmed or provided in another way, for example provided manually, e.g. via an input device, and / or be received from an external source operatively connected to the tinnitus treatment device. Additionally and / or alternatively the tinnitus treatment device may determine the tinnitus property information, e.g. comprise a sensor for providing a property signal representative for the tinnitus property information. The control unit is configured to activate the acoustic source to provide a treatment sound having at least one treatment frequency to the ear on the basis of the tinnitus property information. The treatment sound may comprise a single frequency, or be a mixture of multiple frequencies, sequences and / or combinations of sounds. The treatment sound may for example be a pure tone, but may for example also comprise a noise, hiss and / or hum. The treatment sound may for example comprise frequencies in the audible spectrum, for example between 8 kHz and 12 kHz, such as 9-11 kHz. It has been found that these frequencies are especially suited at damaging the part of the ear responsible for generating the perceived tinnitus sound. The sound level, i.e. loudness, and / or a pulse duration of the treatment sound are selected to damage a part of the ear responsible for the respective origin property, e.g. a hair cell responsible for the respective origin frequency, e.g. such that an actual tinnitus sound perceived by the user is perceived at a decreased sound level. The hair cell may be located within the spiral organ of Corti on the basilar membrane in the cochlear on the inner ear of the affected ear of the user. The treatment sound may be provided as a pulse. The duration may be the duration of the pulse. The sound level and / or the pulse duration may be related to each other via a predetermined relationship. The sound level and / or the pulse duration may for example be pre-programmed or provided in another way, for example provided manually, e.g. via an input device, and / or be received from an external source operatively connected to the tinnitus treatment device. Additionally and / or alternatively the tinnitus treatment device may determine the sound level and / or the pulse duration on the basis of the tinnitus property information. The treatment sound may comprise single pulse having the pulse duration, or a combination of pulses, e.g. a sequence. The selected pulse duration may comprise a respective duration for each pulse in the sequence, an amount of pulses and / or a duration for one or more silences between respective pulses. The treatment sound may comprise multiple sounds that differ from each other for one or multiple pulses in the sequence. The number of pulses may be selected to damage the part of the ear responsible for the respective origin property at the selected sound level and / or pulse duration. The sound level and the pulse duration may be selected to, at the at least one frequency of the treatment sound, paralyse the part of the ear responsible for the respective origin property, e.g. a hair cell responsible for the respective origin frequency. By having a treatment sound provided to damage the part of the ear responsible for the perceived tinnitus sound, the actual source of the tinnitus sound may be treated. As all remedies known in the prior art are only able to address symptoms, the invention is the first to address an undue trigger of nerves to send signals to the brain that thereby cause a perceived tinnitus sound. As such, the invention allows treatment of cochlear tinnitus and thereby provides a revolution in tinnitus treatment. The invention has several additional advantages: Firstly, the tinnitus treatment according to the invention is relatively simple, effective and non-invasive. For example, a tinnitus treatment device may be provided to a user such that the treatment, e.g. repeated treatments, could be performed conveniently. Secondly, by addressing the source of the cochlear tinnitus, the effects of treatment may last for a relatively longer period of time, e.g. permanently, such that the tinnitus treatment according to the invention may even completely turn off the perceived tinnitus sound. Finally, the tinnitus treatment may be more efficient and economic compared to existing symptomatic tinnitus treatments. The property information may for example comprise a location, or specific part of the ear. In an embodiment, the property information is representative for at least one origin frequency. The origin frequency may for example be the frequency of a perceived tinnitus sound. The part of the ear responsible for the perceived tinnitus sound, e.g. a hair cell, is usually responsible for receiving at least one origin frequency, such that the property information may be representative for the respective part of the ear to be damaged for tinnitus treatment. The treatment sound may be selected near the at least one origin frequency or a harmonic thereof. The treatment sound may deviate, within a predetermined frequency range, from the at least one frequency of the at least one origin information. It has been found that treatment sounds that are near the origin frequency may advantageously contributing to specifically damaging the part of the ear that is responsible for the perceived tinnitus sound, while keeping damage to other parts of the ear relatively limited. In a further embodiment, the treatment sound comprises the at least one origin frequency. This way, the part of the ear may be treated specifically. Further, this way, the user may verify the correctness of the treatment sound by confirmation that, during treatment, the perceived tinnitus sound is increased in loudness. Instead of a single treatment sound a treatment series may be provided. The control unit may be configured to activate the acoustic source to provide the treatment series. The treatment series may comprise a number of consecutive treatment sounds, the same or mutually different. The number, the sound level and / or the pulse duration of the respective treatment sounds in the treatment series may be selected to damage a part of the ear responsible for the respective origin property with the treatment series. This approach may be advantageous as a relatively lower sound level and / or pulse duration may be effective at damaging the part of the ear when being provided multiple times, compared to a sound that is provided a single time. The sound level required for treatment may vary depending on, e.g. user, the hair cell that is damaged, the extend of damage, and the frequency of the perceived tinnitus sound. The sound level provided by the tinnitus treatment device may be related to the pulse duration. E.g. a predetermined combination may be provided in the tinnitus treatment device, wherein the sound level and / or the pulse duration is selected and wherein, respectively, the pulse duration and / or the sound level is determined by the control unit. For example, a sound level of 100 dB may be found to induce sufficient hearing damage upon receiving 15 minutes of treatment sound, whereas a sound level of 110 dB may provide effective treatment at a pulse duration In an embodiment, the sound level ofthe treatment sound is at least 100 dB, such as at least 115 dB, for example at least 120 dB. The sound level may for example be selected within a range, e.g. 100-125 dB. It has been found that these sound levels are especially suited at treating cochlear tinnitus while keeping damage to other parts of the ear relatively limited. The acoustic source may be configured to provide the sound level. In an embodiment, the pulse duration is selected to induce a movement in a basilar membrane of the ear substantially limited to the treatment frequency and / or harmonics thereof. The pulse duration may be selected by taking into account an inertia of the basilar membrane. In particular, the pulse duration may be such that the basilar membrane is moved at the treatment frequency, whereas movement at other frequencies is dampened due to the inertia of the basilar membrane. The pulse duration may be selected in dependence of a inertia of the basilar membrane. The inertia may be preprovided, e.g. be determined on the basis of measurements, preprogrammed, received from an external source, or provided in another way, wherein the pulse duration is selected on the basis of the preprovided inertia. Alternatively, the pulse duration may be selected without pre-provision of the inertia, e.g. empirically. The pulse duration and the preprovided inertia may be adapted to the specific usen It has been found that in this way, ear damage at frequencies other than the desired at least one frequency of the treatment sound may be reduced, such that treatment may be relatively more effective whereas additional damage to other parts of the ear may be relatively limited. In an embodiment, the pulse duration is less than 1 second, for example 10 ms 750 ms, such as 20 ms 500 ms. It has been found that these may be practically applicable values of the pulse duration for treatment of the part of the ear to be treated, at relatively little collateral damage to other parts of the ear. In an embodiment, the tinnitus treatment device comprises a protection unit for protecting a non-affected ear of the user from the treatment sound. The protection unit may protect the nonaffected ear from damage while the other ear of the user is treated. The protection unit may be configured to provide protection at the at least one frequency of the treatment sound. The protection unit may comprise a soundproofing element, e.g. an earpad. The soundproofing element may comprise a sound insulating material, such as a foam, rubber or mineral wool. Additionally and / or alternatively, the protection unit may comprise a second acoustic source for providing cancelling sounds that at least partially cancel the treatment sound before reaching the nonaffected ear. The cancelling sounds may be selected to cancel the treatment sound and for example comprise a phase-shifted treatment sound. The second acoustic source may be directional may and may be configured to direct the cancelling sounds to the non-affected ear. In an embodiment, the tinnitus treatment device comprises a visual indicator for displaying a visual signal to the user, configured to indicate the treatment sound and / or the tinnitus property information, wherein the acoustic source is configured to provide sound in correspondence with the visual signal to the user, and wherein the visual indicator and the acoustic source are operatively connected to each other. It has been found that by showing visual indications, treatment comfort for the user may be improved. Further, treatment efficacy may be further improved by the provision of visual indications, e.g. due to psychosomatic factors. In particular, it has been found that by engaging the brain by providing a visual indication in addition to the treatment sound, the chances of overcompensation of the brain after reducing the perceived tinnitus sound, e.g. by having the brain producing new perceived tinnitus sounds, may be reduced. The visual indicator may comprise a light emitter element configured to emit light, such as an lamp. The visual indicator may be configured to vary properties of the visual signal to indicate the tinnitus property information. For example, the visual indicator may be configured to vary intensity, wavelength(s) and / or on / off frequency of the visual signal in dependence of the frequency and / or a sound level of the provided sound. Additionally or alternatively, the tinnitus property information may be shown by a symbol, value, or other element, for example displayed in a virtual interface. In an embodiment, the visual indicator comprises a display configured to display the virtual interface. The acoustic source may be configured to provide sounds in correspondence with the virtual interface to the user. It has been found that by displaying a virtual interface, user-friendliness of the device can be improved. In particular, immersion of the user in the treatment and thereby effectiveness may be improved. The display may for example be a monitor, a portable display, such as a phone screen, or a virtual reality display. The virtual interface may be an interface comprising menus, buttons and / or other controls. In the virtual interface, a virtual world may be shown. The virtual interface may depict an overview of the ear of the user, e.g. a representation of the cochlea and / or of nerves between the ear and the brain. The virtual interface may be configured to visualise the tinnitus property information, e.g. by depicting an origin location on the overview of the ear of the user. The virtual interface may be configured to depict the damage by the treatment sound on the overview of the ear of the user. It has been found that this way, the brain receives visual indication of state of the ear before and / or after treatment, such that the chances of overcompensation of the brain after reducing the perceived tinnitus sound, e.g. by having the brain producing new perceived tinnitus sounds, may be further reduced. In an embodiment, the tinnitus treatment device further comprises an input device for receiving input to provide the tinnitus property information. The input device may be operatively connected to the control unit. The input device may additionally and / or alternatively be configured to receive other types of information, such as a user confirmation of improvement in, i.e. reduction of, the perceived tinnitus sound. The input device may for example be configured to receive a confirmation whether the actual tinnitus sound perceived by the user is perceived at a decreased sound level. In an embodiment, the tinnitus treatment device, e.g. the control unit, may be arrangeable in a distinct tinnitus type finding mode. In the tinnitus type finding mode, the tinnitus treatment device is configured to assist in differentiating between a brain-induced tinnitus and a cochlear tinnitus, e.g. to determine whether the tinnitus is braininduced or not and / or to switch into the desired treatment mode when the tinnitus not brain-induced. This way, the tinnitus treatment device can be used for differentiating between the type of tinnitus that is affecting the user, and, if so, treatment may be performed advantageously with the same device. As such, treatment may be performed more efficiently and / or more precise, e.g. as the tinnitus property information may be determined with the same device. In an embodiment, the tinnitus treatment device is configured to, in a tinnitus type finding mode: provide, via the acoustic source, reference sounds individually, while displaying, via the visual indicator, a sound property indicator representative for at least one property, such as a sound level or frequency, of the respective reference sound, wherein, while providing the sounds, the sound property indicator indicates a decreasing sound level of the respective reference sounds; display, via the visual indicator, a sound property indicator representative for at least one property of a perceived tinnitus sound, without providing the perceived tinnitus sound via the acoustic source, wherein the sound property indicator indicates a decreasing sound level of the perceived tinnitus sound, such that it can be determined whether the actual tinnitus sound perceived by the user is perceived at a decreased sound level, e.g. on the basis of received input; and optionally, switch into the treatment mode when the actual tinnitus sound is not yet perceived at a decreased sound level. The visual indicator may comprise a display and / or the visual signal may comprise a virtual interface. The acoustic source may be configured to provide sounds in correspondence with signals shown on the display. For example, sounds that match with the visual signal provided via the virtual interface. The sounds are considered reference sounds as they form a reference to the user for the sound property indicator, e.g. by provision of the reference sounds while providing the sound property indicator, the user may learn that the sound property indicator is representative for at least one property of the reference sound, e.g. the intensity and / or frequency thereof. The device may be configured to provide each respective reference sound at a varying intensity, whereby the sound property indicator is varied accordingly to indicate the decreasing intensity, for example by increasing and / or decreasing the intensity of the visual signal. The device may be configured to provide each reference sound at a decreasing intensity, whereby with each sound, the sound property indicator is provided with a decreasing intensity of emitted light. The reference sounds may be sounds that are commonly perceived as tinnitus sound, or any other type of sound. The sounds may be substantially close to a tinnitus sound perceived by the user. For example, the reference sounds may be located within a predetermined frequency range from each other and / or from the tinnitus sound. The sounds may be any type of sound, e.g. comprise a pure tone, noise, hiss, and / or combination thereof. The sounds may each be of the same type or of mutually varying types. While providing a reference sound, the sound property indicator indicates a decreasing intensity of the respective reference sound. The tinnitus treatment device is further configured to display, via the visual indicator, a sound property indicator for a perceived tinnitus sound, without providing the perceived tinnitus sound via the acoustic source, wherein the sound property indicator indicates a decreasing intensity of the perceived tinnitus sound. This way, an actual tinnitus sound perceived by the user may be perceived at a decreased intensity. By displaying a sound property indicator, the brain of the user may be tricked by perceiving the sound properties indicated by the sound property indicator to be representative for the perceived sounds. It has been found that by providing reference sounds, the realism of the visual signal is increased, as the brain of the user may experience the sound property indicator to be representative for the sound properties of multiple sounds. Therewith the brain of the user may perceive a link between the sound property indicator and all sounds perceived by the user, including sounds that are not provided to the user via the acoustic source, such as an actual tinnitus sound perceived in the brain by the user. As such, a coupling between a visual stimulus, i.e. the sound property indicator, and perceived sound may be established by the brain of the user. As the reference sounds are provided with the same device, effects related to the reference sounds, such as a perception of decreasing intensity, may also be perceived when the sound property indicator indicates sound properties representative for the actual tinnitus sound. Thus, by indicating a decreasing intensity for the reference sounds, a decreasing intensity may be perceived for reference sounds, and the user may subsequently also perceive a decreasing intensity for an actual tinnitus sound that is perceived in the brain, in case of a tinnitus that is at least partially braininduced. As such, the sound property indicator representing a decreasing intensity may be inextricably linked to a decreasing tinnitus sound in the brain of the user, resulting in an effective decrease of intensity of the tinnitus sound in case of a tinnitus that is at least partially brain- induced. Therewith, the tinnitus treatment device may be configured to treat both brain-induced tinnitus (i.e. originating in the brain, e.g. as the result of phantom noise, e.g. in response to hearing damage or a medical condition) and cochlear tinnitus (i.e. originating in the ear, e.g. by triggering nerves, e.g. as a result of physical damage of hair cells). Further, the effect may be relatively long-lasting, such thatjust by remembering the sound property indicator, the effect of perceived decreased intensity of an actual tinnitus sound may potentially be invoked without even requiring the tinnitus treatment device. It has been found that the effect may even result in the perceived tinnitus sound to be perceived as being completely turned off. Furthermore, when the tinnitus is not at least partially braininduced, it has been found that the actual tinnitus sound perceived by the user is not yet perceived at a decreased sound level, e.g. on the basis of received input; such that, with the tinnitus treatment device according to this embodiment, one can differentiate between a brain-induced tinnitus and a cochlear tinnitus. The tinnitus treatment device may be configured to switch into the treatment mode when the actual tinnitus sound is not yet perceived at a decreased sound level. Therewith, a relatively effective treatment may be obtained that may treat and differentiate between brain-induced and cochlear tinnitus, such that it may also be performed, for example for repetition, at home and without continuous medical supervision. The input unit may be configured to turn the treatment device on and / or off and thereby control the visual indicator. For example, the tinnitus device may be configured to be arranged in the treatment mode upon receipt of input. The input unit may comprise a push button, such that the input is a button push. The input unit may comprise a reference sound selector, e.g. a switch button. The acoustic source may be congured to provide the reference sounds in dependence of the state of the reference sound selector. For example, depending on a user, specific types or frequency ranges of reference sounds may be more effective. Elderly may have impaired hearing of higher 1O frequency sounds. Therewith, by having a reference sound selector, effectiveness of the treatment may be improved. Additionally and / or alternatively, the input unit may be configured to navigate through the virtual interface. The input unit may comprise multiple buttons, a motion sensor and / or another device capable of receiving input, e.g. from the user. The input device may for example comprise a camera and be configured to identify movements of the user as input. The camera may be arranged to capture hand movements of the user. This way, the user may be able to control the visual signal by providing hand gestures. The display may be configured to show virtual hands of the user that represent hand movements captured by the camera. In addition to user-friendliness, it has been found that this may further improve therapeutic effectiveness. Additionally or alternatively, the input device may comprise another device, such as a remote control, a keyboard, or a mouse. The acoustic source may be attached to the visual indicator or be located remotely, for example in a headset. The acoustic source may comprise a left acoustic source corresponding to a left ear of the user and a right acoustic source corresponding to a right ear of the user. The tinnitus treatment device may be configured to provide the indicator for the perceived tinnitus sound upon receipt of a specific input via the input unit, and / or automatically, e.g. in a sequence such as after providing all reference sounds, in between and / or interleaved with the provision of reference sounds. In an embodiment, the tinnitus treatment device comprises a housing and the control unit, the acoustic source, the visual indicator and / or the input unit are arranged within the housing. This way, treatment may be performed using a relatively compact device. The treatment device may be housed in a single housing. The housing may be portable. In particular, the housing may be configured to be held in the hand ofthe user and / or the housing may be configured to be worn on the head of a user. In an embodiment, the display is configured to display the sound property indicator in the virtual interface. This way, realism of the virtual interface is further improved and the user may receive less distraction during treatment, potentially enhancing effectiveness. In an embodiment, the tinnitus treatment device may be arrangeable a distinct tinnitus sound finding mode. In the tinnitus sound finding mode, the tinnitus treatment device is configured to determine a tinnitus sound comprising at least one frequency. The tinnitus sound may be pre- programmed, e.g. by a clinician, received via a connection and / or be determined in dependence of received user input. The tinnitus sound may correspond to an actual tinnitus sound that is perceived by the user, e.g. the person to be treated. The tinnitus treatment device may be further configured to, in the tinnitus sound finding mode: determine a tinnitus sound comprising at least one frequency, e.g. on the basis of received input. In a further embodiment, the tinnitus treatment device may be configured to, in the tinnitus type finding mode: determine neighbouring sounds, each comprising at least one frequency that deviates, within a predetermined frequency range, from the at least one frequency of the generated tinnitus sound; and provide, via the acoustic source, the neighbouring sounds as reference sounds, while indicating, via the visual indicator, a sound property indicator representative for at least one property, such as a sound level or frequency, of the respective neighbouring sound, wherein, while providing the neighbouring sounds, the sound property indicator indicates a decreasing sound level of the neighbouring sounds. In other words, in the tinnitus type finding mode, the device may be configured to provide, via the acoustic source, the neighbouring sounds individually, while indicating, via the visual indicator, a sound property indicator representative for at least one property, such as a intensity or frequency, of the respective neighbouring sound, wherein, while providing the neighbouring sounds, the sound property indicator may indicate a decreasing intensity of the neighbouring sounds. The neighbouring sounds may be sounds that are perceived as close to the generated tinnitus sound. The neighbouring sounds may be substantially equal to the generated tinnitus sound. The neighbouring sounds may be of the same type, e.g. comprise a pure tone, noise, hiss and / or hum, as the tinnitus sound. The tinnitus treatment device may be configured to provide the neighbouring sounds subsequently in fashion of an increasing frequency, or alternatively, the neighbouring sounds may be provided randomly. The tinnitus treatment device may be configured to provide the generated tinnitus sound in between the neighbouring sounds, during the tinnitus type finding mode, such that provision of the individual neighbouring sounds and the generated tinnitus sound is interleaved with each other. This way, effectiveness of the therapy may be further improved. In contrast with prior art, a tinnitus sound is generated, after which not only the generated tinnitus sounds is provided to the user, but also neighbouring sounds. By displaying a sound property indicator, the brain of the user may be tricked by perceiving the sound properties indicated by the sound property indicator to be representative for the perceived sounds. It has been found that by providing neighbouring sounds, the realism of the visual signal is increased, as the brain of the user may experience the sound property indicator to be representative for the sound properties of multiple sounds. Therewith, the brain of the user may perceive a link between the sound property indicator and all sounds perceived by the user, including sounds that are not provided to the user via the acoustic source, such as an actual tinnitus sound perceived in the brain by the user. As such, a coupling between a visual stimulus, i.e. the sound property indicator, and perceived sound may be established by the brain of the user. As the neighbouring sounds are neighbours of the generated tinnitus sound, effects related to the neighbouring sounds, such as a perception of decreasing intensity, may also be perceived when the sound property indicator indicates sound properties representative for the actual tinnitus sound. Thus, by indicating a decreasing intensity for the neighbouring sounds, a decreasing intensity may be perceived for the neighbouring sounds, and the user may subsequently also perceive a decreasing intensity for an actual tinnitus sound that is perceived in the brain, in the case of a tinnitus that is at least partially brain-induced. Therewith, a relatively effective treatment may be obtained that may treat and differentiate between brain-induced and cochlear tinnitus, such that it may also be performed, for example for repetition, at home and without continuous medical supervision. In an embodiment, in the tinnitus type finding mode, the displayed sound property indicator comprises a visual stimulus having a variable light intensity, such as a fadeable light, and the visual indicator is configured to decrease the light intensity of the visual stimulus to indicate a decreasing intensity of the provided sound. It has been found that by using the combination of sounds and a visual stimulus, the brain-induced tinnitus treatment may have a stronger effect. As a result of cross modal interference, a user may experience a fusion of experienced intensities of the perceived visual stimulus and the perceived sound. In other words, the user may experience an increase or decrease in perceived intensity of sound, even when the sound is provided at a constant intensity by the acoustic source, by viewing a variable light intensity. For example, each visual stimulus, e.g. fadeable light, may correspond to a neighbouring sound or the generated tinnitus sound. Each visual stimulus, e.g. fadeable light, may correspond to at least one frequency. Light intensity may for example be decreased by changing to a darker colour, and / or by decreasing brightness or illumination. By influencing light perception, the perceived intensity of both the neighbouring sounds as of the actual tinnitus sound perceived by the user may potentially be influenced without actively inuencing sound from the acoustic source. In an embodiment, the tinnitus treatment device may be arrangeable a distinct in a tinnitus type check mode. In the tinnitus type check mode, the tinnitus treatment device is configured to check with the user whether the treatment sound is able to treat an actual tinnitus tone perceived by the user. It has been found that, by having a check mode, the chances of provision of an ineffective treatment sound and / or unnecessary damage to the ear may be reduced. The tinnitus treatment device may be configured to, in the tinnitus type check mode: activate the acoustic source to provide a check sound at the at least one treatment frequency, e.g. at a sound level lower than the treatment sound and / or for a pulse duration shorter than the treatment sound; The tinnitus treatment device may be further configured to, in the tinnitus type check mode indicate, with the visual indicator, the sound level, respectively the pulse duration, for the check sound; and / orto indicate, with the visual indicator, the sound level, respectively the pulse duration, for the treatment sound. The steps of indicating, with the visual indicator, the sound level for the reference sound and / or the treatment sound may be performed in conjunction with the provision of the respective sound via the acoustic source, e.g. during provision of the respective sound and / or shorty before and / or thereafter. This way, the brain may be involved visually and more actively to verify that the treatment sound is correct. The check sound may be substantially identical to the treatment sound, but may be provided at another pulse duration and / or intensity than the treatment sound. The check sound may be a check series comprising a number of consecutive check sounds, the same or mutually different. The number, the sound level and / or the pulse duration of the respective check sounds in the check series may be selected not to damage a part of the ear responsible for the respective origin property with the check series. The check sound may be determined similar to the reference sound as described herein. The number, the sound level and / or the pulse duration of the check sound, respectively the check series, are selected not to damage a part of the ear responsible for the respective origin property. After the steps of activating the acoustic source to provide the check sound, the device may be configured to await a user confirmation, e.g. via the input unit, that the check sound addresses the respective origin property, e.g. that the check sound temporarily affects an actual tinnitus sound perceived by the user. The check sound may be provided to temporarily affect the perceived tinnitus sound, e.g. by decreasing the sound level as a result of temporarily overloading the respective part of the ear and / or by increasing the sound level as the check sound is equal to an actual tinnitus sound perceived by the user. In an embodiment, the check series comprises a number of check sounds, wherein the check sounds are equal to the treatment sounds to be provided, but wherein the number of the respective check sounds is selected lower than the number of the respective treatment sounds in order not to damage a part of the ear responsible for the respective origin property. It has been found that this way, correctness of the check sound may be verified relatively realistically, whereas long-term damage of the part of the ear may be limited. The tinnitus treatment device may be further configured to, in the tinnitus type check mode, switch into the treatment mode upon receiving a user confirmation, e.g. via the input unit, that the check sound addresses the respective origin property, e.g. that the check sound temporarily affects an actual tinnitus sound perceived by the user. In an embodiment, the visual indicator comprises a display configured to display a virtual interface, wherein the tinnitus treatment device is further configured to, in a tinnitus sound finding mode: display, in the virtual interface, a sound generator controllable via the input unit; display, in the virtual interface, a control indicator that indicates control of the sound generator in dependence of the received input; determine the tinnitus property information of the perceived tinnitus sound comprising at least one frequency in dependence of the received input; and, optionally, provide the generated tinnitus sound via the acoustic source. By having a sound generator, the generated tinnitus sound may be generated relatively realistically to approach an actual tinnitus sound perceived by the user as much a possible. The sound generator may be configured to display information of the receptive location(s) of the generated sound on the cochlea to engage the brain of the user in the sound generation process. The display may be configured not to display any frequency values as it has been found that this way, user biases with respect to the perceived tinnitus sound may be avoided. In an embodiment, the tinnitus treatment device, e.g. the control unit, may be arrangeable in a distinct tinnitus sound finding mode. In the tinnitus sound finding mode, the tinnitus treatment device is configured to determine a tinnitus sound comprising at least one frequency. The tinnitus sound may be preprogrammed, e.g. by a clinician, received via a connection and / or be determined in dependence of received user input. The tinnitus sound may correspond to an actual tinnitus sound that is perceived by the user, i.e. the person to be treated. In an embodiment, the tinnitus treatment device is further congured to, in the tinnitus sound finding mode, display, in the virtual interface, a sound generator controllable via the input unit; and display, in the interface, a control indicator that indicates control of the sound generator in dependence of the received input; to determine the tinnitus sound comprising at least one frequency in dependence of the received input, and to provide the generated tinnitus sound via the acoustic source. In this embodiment, in the tinnitus type finding mode, the device may be configured to determine neighbouring sounds, each comprising at least one frequency that deviates, within a predetermined frequency range, from the at least one frequency of the generated tinnitus sound; and to provide, via the acoustic source, the neighbouring sounds individually, while indicating, via the visual indicator, a sound property indicator representative for at least one property, such as a intensity or frequency, of the respective sound, wherein, while providing the sounds, the sound property indicator indicates a decreasing intensity of the sounds. The sound generator may be provided with virtual controls, such as knobs or buttons, to be controllable via the input unit. The sound generator may be shown in the visual signal as an organ. In particular, the organ may e.g. be shown to be connected to a representation of a part of a human, e.g. a brain or part of the ear, such as a cochlea, to help convincing the brain of the user that the sound generator is representative for sounds perceived by the user. The control indicator may for example be a movement of the virtual controls, such as a rotation of the knobs or movement of the buttons, or another indicator, such as a meter, light bulb or another change in the displayed visual signal. The control indicator may additionally or alternatively provide an indication of signal direction of the sound, and for example indicate that a signal is sent to a part of the ear or brain of the user, or coming therefrom. The tinnitus treatment device may be configured to ask the user to generate a tinnitus sound that mimics an actual tinnitus sound perceived by the user, for example via a request on the display or via the acoustic source. This way, the user may recreate a perceived tinnitus sound such that the generated tinnitus sound is closely resembles a perceived tinnitus sound. In particular, the generated tinnitus sound may be substantially equal to an actual tinnitus sound perceived by the user. The generated tinnitus sound may comprise a single frequency, or be a mixture of multiple frequencies. The sound generator may enable generation of a tinnitus sound comprising multiple frequencies, sequences and / or combinations of sounds. The generated tinnitus sound may for example be a pure tone, but may for example also comprise a noise, hiss and / or hum. The sound generator may comprise a representation of an organ and / or a representation of a body part of the user, for example a representation of a part of the ear. The sound generator may be a representation of a body part, e.g. a part of the brain or a part of the ear, provided with input buttons and / or keys for inputting a sound into the represented body part. The sound generator may additionally or alternatively comprise a representation of a music instrument, such as a keyboard or DJ panel. The sound generator may comprise a representation of nerves of the user between the part of the ear and the brain. In a particular, a signal direction of perceived sounds between the ear and the brain may be shown to the user. It has been found that providing the signal direction may help the user in understanding the tinnitus which promotes effectiveness of therapy. The sound generator may comprise inputs for providing various frequencies in a constant tone, but may additionally or alternatively also comprise inputs for generating a tinnitus sound that comprises a combination of frequencies, such as a noise, hiss or hum. By having a combination of frequencies, a generated tinnitus sound may mimic an actual perceived tinnitus sound relatively closely. The frequency range may be preprogrammed, or provided in another way, for example be input by the user or received from an external controller before the tinnitus treatment device is arranged in the treatment mode. The tinnitus treatment device may be configured to be arranged in the tinnitus finding mode before being arranged in the treatment mode for each new user. The control unit may be configured to determine the tinnitus origin property on the basis of the generated tinnitus sound. In particular the tinnitus origin property may comprise a property, such as the frequency, of the generated tinnitus sound and / or be derived from the generated tinnitus sound, e.g. an origin location on the cochlea may be determined on the frequency of the generated tinnitus sound. The tinnitus treatment device may be configured to automatically switch between the tinnitus sound finding mode, the tinnitus type nding mode, the tinnitus check mode and the treatment mode, or may be configured to be switched manually, for example by the user or by an external controller. In an embodiment, the tinnitus treatment device comprises at least one head mount, wherein the acoustic source and / or the protection unit are arrangeable in a respective operating position by providing the head mount to a head of the user. This way, userfriendliness of the device, and therewith therapeutic efficacy may be further improved. It has been found that by having a head mount, the sound may be directed into the affected ear. Further, by having a head mount the treatment sound may be provided relatively close to the ear, e.g. such that a lower sound level needs to be provided by the acoustic source and / or such that a higher sound level can be achieved in the cochlea of the affected ear. This way, damage to the affected ear may be incurred more effective. It may further be provided that the sound level may be relatively lower due to the small distance between the acoustic source and the affected ear, and thereby protect the non-affected ear. Also, the tissue surrounding the affected ear may dampen the treatment sound from the probe before reaching the non affected ear. In an embodiment, the tinnitus treatment device comprises a probe to be positioned at, e.g. in, an affected ear, wherein the acoustic source is provided in the probe and is arrangeable in an operating position by providing the probe to, e.g. in, an ear of the user. It has been found that by having a probe, the sound may be directed into the affected ear. Further, by having a probe the treatment sound may be provided even closer to the cochlea compared to an on- ear head mount. This way, damage to the affected ear may be incurred more effective. It may further be provided that the sound level may be relatively lower due to the insertion depth of the probe into the affected ear, and thereby protect the nonaffected ear. Also, the tissue surrounding the affected ear may dampen the treatment sound from the probe before reaching the non-affected ear. In an embodiment, the tinnitus treatment device comprises a measurement unit. The measurement unit may be configured to measure information of the affected ear representative for functionality of the affected ear, e.g. an audiogram or auto-acoustic emissions. The information of the affected ear may comprise the tinnitus property information. The measurement unit may be arranged in the probe. This way, functionality of the affected ear may be measured and treatment may potentially be provided using a single device, which could contribute to treatment efficacy. In an embodiment, the tinnitus treatment device comprises a portable device, such as virtual reality goggles, wherein the visual indicator and the acoustic source are provided in the portable device, and wherein the tinnitus treatment device is configured to, in the tinnitus sound finding mode, either visually via the visual indicator or aurally via the acoustic source, request the user for input to control the sound generator via the input unit to generate a tinnitus sound that resembles an actual tinnitus sound perceived by the user. This way, user- friendliness of the device, and therewith therapeutic efficacy may be further improved.

The tinnitus treatment device and the data processing unit may be configured to transmit and receive only non-personalised data to each other. This way, safety of data is ensured in the technical design of the tinnitus treatment system itself. It has been found that this way, the selection criteria of a suitable treatment sound, e.g. the at least one frequency, the sound level and / or the pulse duration, may be optimised according to actual success data and / or tinnitus property information. The data processing unit may for example comprise a digital twin model of the human cochlea, a machine learning model and / or another type of model or combination thereof to optimise selection of the treatment sound and thereby improve therapeutic efficacy.

The acoustic source and the measurement unit may be provided in the probe and be arrangeable in an operating position by providing the probe to an ear of the user. The tinnitus treatment device 1 of Fig. 2 comprises a portable device, such as virtual reality goggles or phone,, wherein the visual indicator 5 and the acoustic source 2 are provided in the portable device, and wherein the tinnitus treatment device 1 is configured to, in the tinnitus sound finding mode, either visually via the visual indicator 5 or aurally via the acoustic source 2, request the user for input to control the sound generator 7 via the input unit to generate a tinnitus sound that resembles an actual tinnitus sound perceived by the user. At least two tinnitus treatment devices 1 according to any of the above embodiments may be provided, further configured to request the user aurally or visually to input treatment success data representative for perception of the actual tinnitus sound. Further, a data processing unit may be provided, configured to receive tinnitus property information, the treatment success data, and the treatment frequency, the sound level and / or the pulse duration from each of the tinnitus treatment devices 1. The tinnitus treatment devices 1 may be configured to transmit non-personalised information, in particular the frequency range and treatment success data to the data processing unit, and to receive the predetermined frequency range from the data processing unit. The data processing unit is a selection unit and is configured to correlate received treatment success data to respective treatment frequency, the sound level and / or the pulse duration and to derive optimal treatment strategies. In particular, the data processing unit may comprise a machine learning model. Upon receipt of tinnitus property information, the data processing unit is configured to select a treatment sound on the basis of the received property information, treatment success data, the treatment frequency, the sound level and / or the pulse duration and to transmit the selected treatment sound to at least one of the tinnitus treatment devices 1, such that the respective treatment device 1 may perform treatment using the most successful treatment sound selected by the data processing unit. In use, via the acoustic source 2, a check sound may be provided first, at the at least one treatment frequency at a sound level lower than the treatment sound and / or for a pulse duration shorter than the treatment sound to verify whether the treatment sound has an effect. With the visual indicator 5, the sound level, respectively the pulse duration, for the check sound may be indicated. The treatment sound is then provided to an ear of the user 99 on the basis of the predetermined tinnitus property information representative for at least one origin property of a tinnitus sound perceived by the user, such as the origin frequency. The treatment sound comprises at least one treatment frequency at a sound level and for a pulse duration that are selected such that a part of the affected ear responsible for the respective origin property, in particular a hair cell responsible for the respective origin frequency, is damaged and such that an actual tinnitus sound perceived by the user is, upon receipt of the treatment sound and damaging of the respective part of the affected ear, perceived at a decreased sound level. During provision of the treatment sound, the sound level, respectively the pulse duration, for the treatment sound, are indicated with the visual indicator 5. The tinnitus property information may be input manually via the input device 6, may be received from an external source, may be determined by the tinnitus treatment device itself and / or may be provided in any other way. For example, in Fig. 2, the sound generator 7 as shown in Fig. 4 may be provided in virtual interface 50, controllable via an input unit 6 to generate a sound upon request to the user 99 to control the sound generator to generate a tinnitus sound that resembles an actual tinnitus sound perceived by the user 99. The generated tinnitus sound comprises at least one frequency, and the tinnitus property information is determined on the basis of the at least one frequency, e.g. comprises the at least one frequency. In particular, the sound generator may be shown first, in a tinnitus sound finding mode, after which the tinnitus treatment device is arranged in a tinnitus type nding mode to differentiate between a brain-induced tinnitus and a cochlear tinnitus, e.g. by providing reference sounds and displaying a sound property indicator, and subsequently providing a sound property indicator for the generated tinnitus sound, without providing the generated tinnitus sound. Both during provision of the reference sound, and the indication of the sound property indicator for the generated tinnitus sound, a decreasing sound level is indicated via decreasing light intensity of bulb icon 51 and / or display 5. As such, when the tinnitus is braininduced, the actual tinnitus tone perceived by the user will be experienced at a decreased intensity after indication of the decreasing sound level for the generated tinnitus sound. However, when the tinnitus is cochlear, no effect will be noticed by the user yet, and it can be determined that the tinnitus is a cochlear tinnitus. The device is then arranged in the treatment mode, or alternatively, first in the tinnitus check mode and subsequently in the treatment mode. During repetitions of the treatment, if any, the tinnitus treatment device may be arranged directly in the desired mode. In the tinnitus treatment mode, the virtual interface 50 may for example depict the hair cell and / or nerves 21, 22 that represent the origin of the cochlear tinnitus. Upon provision of the treatment sound, the paralysed hair cells in the cochlea are indicated, e.g. via line 22. Then, another treatment sound may be provided directed to another frequency hair cell, as indicated with line 21. One or multiple pulses or treatment sounds may be provided combined, sequentially, etc. As the treatment sound is provided with a pulse duration, the pulse duration may be adjusted to achieve the desired level of damage of tinnitus-origin hair cells, while leaving non-tinnitus hair cells in tact as much as possible. The method may be provided as a software application, eg a machine readable instruction comprising instructions which, when the instruction is executed by a control unit operatively connected to an acoustic source for controlling the acoustic source, cause the control unit to perform the method according to any of the embodiments disclosed herein.
