The described implementations of ANC are considered insufficient to meet customer expectations regarding perceived value, particularly in the higher-priced vehicle segment.
[0004] The purpose of the invention is to enhance the impression of value.

The problem is solved in particular by an ASS with the features of claim 9. The problem is solved in particular by a computing device with the features of claim 10. The problem is solved in particular by a computer program product with the features of claim 11. The problem is solved in particular by a storage device with the features of claim 12. Further features and details of the invention will become apparent from the dependent claims, the description, and the drawings.Features and details described in connection with the motor vehicle according to the invention naturally also apply in connection with the method, computer program product, computing device, storage device, and ASS according to the invention. The reverse is also true, so that the disclosure of the individual aspects of the invention always refers to, or can refer to, each other.
[0006] According to one aspect, the problem is solved in particular by a motor vehicle with the features of claim 1.
[0007] A motor vehicle may have at least one actuating device, designed and configured to move at least one actuator of at least one electronically controllable component. The motor vehicle may have at least one active noise cancellation device (ANC), designed and configured to suppress noise from the component when it moves. The motor vehicle may have at least one active sound generation device (ASS), designed and configured to generate noise when the component moves.
[0008] An actuating device is, in particular, a mechanical or electronic device in a motor vehicle that can serve to enable the use and operation of components in the vehicle. These can be, for example, switches, buttons, or (touch) sensors that can be operated by the driver or other occupants. Mechanical components can be electronically coupled to circuits in order to communicate an actuation electronically and thereby control the actuator, but also to communicate with a computer unit to enable control of the ANC (Active Noise Cancellation) or the ASS (Automatic Stability Control).
[0009] An actuator is, in particular, a component in a motor vehicle that can be used to move another component or bring it into a specific position. An actuator can, for example, have an electric motor that is supplied with electricity to perform a movement of the electronically controlled component to be moved.
[0010] An electronically controlled component is, in particular, a component in a motor vehicle that can be controlled via an electronic circuit and / or software. This could be, for example, power windows, an electric tailgate, or a roof roller that can be operated by an electric motor. Other components can also be electronically controlled, as described elsewhere herein.
[0011] A noise reduction device, also known as Active Noise Cancelling (ANC), is a device in a motor vehicle designed to reduce external noise or operating noise within the vehicle. ANC systems use acoustic sensors and amplifiers to measure the acoustic signal inside the vehicle and generate a corresponding counter-signal that cancels out or minimizes the original noise.
[0012] One example of an ANC system application could be an electronically controlled window. When the driver raises or lowers the window, the movement generates a noise that can be measured by an acoustic sensor in the vehicle and suppressed by the ANC system. The ANC system then generates a counter-noise that cancels out or minimizes the original window noise to create a quieter interior. This can be achieved, in particular, by mitigating destructive interference.
[0013] A noise that can be suppressed, which may be generated by the actuator or moving component, could be, for example, the humming of mechanical noises when operating an electronically controlled electric motor. Grinding noises can also be a disturbing sound or one that is perceived as inferior.
[0014] A sound-generating device is, in particular, a device in a motor vehicle that serves to imitate or generate a specific sound. This device can be, for example, a loudspeaker or a surround-sound system used to produce a high-quality sound. The sound-generating device referenced here is not necessarily the same as or identical to a sound-generating device used for active noise cancellation (ANC), which emits an anti-noise wave, as a "counter-noise," to suppress or cancel out interference from a sound perceived as disturbing or inferior.
[0015] Generating a high-quality sound refers specifically to creating a noise or sound that is pleasant and perceived as premium by the vehicle's occupants. This could be, for example, a quiet, deep hum when operating an electronically controlled switch, conveying an impression of quality and craftsmanship. Furthermore, individual alternative sounds can be stored in a database and played to a specific user (as an occupant) when they activate the system.
[0016] The advantages of an ANC system with integrated Active Sound Design can include improved passenger comfort, but also a reduction in background noise.
[0017] Active Noise Cancellation (ANC) in motor vehicles, as described herein in terms of aspects and embodiments, is not limited to the reduction of external noise to improve the interior experience and the well-being of the occupants. Through the aspects and embodiments described herein, active operating noises, especially continuous noises, can be effectively suppressed and, furthermore, replaced by sounds perceived as finished, in order to improve the impression of high-quality and pleasant noise experiences for the vehicle's occupants.
[0018] The described aspects and embodiments aim in particular to improve the perceived quality of the actuated components by introducing an ANC system with integrated Active Sound Design (ASD). The latter can be designed using an Active Sound System (ASS). This system makes it possible not only to reduce external noise but also to suppress active operating noises while simultaneously generating a subjectively pleasant and high-quality sound, noise, and / or sound that can provide the occupant with a positive experience.
[0019] The described aspects and designs can contribute to occupants perceiving electronic components in the vehicle, such as power windows or electric tailgates, not only as functional and useful, but also as pleasant and high-quality. This makes the use of these components more enjoyable and positive, which can lead to an overall increase in comfort within the vehicle.
[0020] From one perspective, at least one of the processes of suppressing the noise to be suppressed and generating the noise to be generated can be continuous over time.
[0021] A continuous-time noise is, in particular, a noise that is emitted continuously over a longer period of time, especially during the course of an activity of the actuator or the electronically adjustable component, e.g., through the humming of mechanical vibrations when operating a component in the interior or exterior of a motor vehicle.
[0022] A noise to be suppressed is, in particular, a continuous noise generated by the operation of an electronic component that may be perceived as disturbing by the vehicle's occupants. Examples could include: the humming of mechanical noises when operating a component activated by a switch or button in the interior, the rushing of air from a moving roof roller, or the clicking of windows when opening and closing, to name just a few.
[0023] A continuous, generated noise is, in particular, a sound that is potentially perceived as high-quality, can be emitted continuously over a longer period, and can be perceived as pleasant and high-quality by the vehicle's occupants. Examples could be the quiet, low hum when operating an electronically controlled window in the interior, the gentle whoosh of airflow when a roof roller moves, or the quiet, low, continuous hum / buzz of mechanical noises when operating a steering column.
[0024] Suppressing noise refers specifically to reducing or canceling out sound generated by a component, for example, through the use of sound absorbers that can transmit vibrations to a vehicle body. Sound sources can also be designed to generate an interference signal in order to cancel out or suppress the noise.
[0025] Generating a noise refers in particular to the emission of sound through a loudspeaker or other sound output unit inside and / or outside the motor vehicle.
[0026] A stored data set (corresponding to a set of sound tracks or sound files containing noises) of possible sounds can be stored in a database containing a multitude of different sounds that can be used for various vehicle controls. This database can be used by the ASS system and methods for controlling active sound design to generate a high-quality sound when operating components in the interior and / or exterior of the vehicle. It can also be provided that an individually tailored or individually selected sound can be played to an occupant or a group of occupants.
[0027] From one perspective, the component can be an adjustable part that can be controlled by a vehicle occupant. Specifically, the component is an electronically controlled part located inside and / or outside a vehicle that can be adjusted or operated by the vehicle occupant, for example, by operating (pushing, sliding, pulling) a suitably designed control device. An occupant is, in particular, a person who is inside a vehicle and is using, driving, or being transported in it.
[0028] Adjustable and operable by an occupant means, in particular, that the component can be actively or manually adjusted by the vehicle's occupant to perform its function. Examples of components adjustable by the occupant could be: electric window regulators, movable sunshades, seat adjustment switches, or an electronic sunroof system, to name a few.
[0029] According to one aspect, the component can be at least one of the following: an (electric) window regulator, an electric (operable) tailgate, an electric (adjustable) sunroof, an electric roof blind, an electric seat adjustment, an electric (electrically adjustable) exterior mirror, an electric (electrically adjustable) steering column, an electric (electrically) movable screen, an electric (electrically) operated glove compartment or an electric (electrically) operated center console flap.
[0030] The component can be provided in various embodiments, some of which are described here as examples, as have already been described elsewhere herein. At least one of the following embodiments can be selected.
[0031] The component in question could be an electric window regulator that moves the window. The ANC system and active sound design can be used to reduce the continuous operating noise and instead generate a more pleasant sound. For example, the window might produce a grinding noise, particularly a squeaking sound, as it passes the seals. This noise can be reduced or eliminated through interference via ANC, allowing, for instance, a pleasant sound with harmonic white noise to be played through the ASS (Active Sound System).
[0032] The component could be an electrically operated tailgate, where the ANC system and active sound design are used to reduce continuous operating noises and instead generate a high-quality sound, for example, when the occupant operates the electric switch to raise or lower the tailgate. This can cause creaking from the hinges, which can be replaced by a harmonious sound, such as a continuous low-frequency scraping.
[0033] The component in question could be an electrically adjustable sunroof, where the ANC system and active sound design are used to reduce the continuous operating noises and instead generate a pleasant sound, for example, when the occupant operates the switch to open or close the sunroof. This can produce grinding noises, particularly squeaking, when passing the seals. These noises can be reduced or eliminated by the ANC, replacing them with a pleasant, harmonic white noise sound played through the ASS (Active Sound System).
[0034] The component could be an electric sunroof blind, for example, to shade a glass sunroof. In this case, the ANC system and active sound design can be used to reduce the continuous operating noise and instead generate a more pleasant sound, such as when the occupant operates the switch. This can create grinding noises, particularly squeaking, when passing the tracks that guide the sunroof blind. These noises can be reduced or eliminated by the ANC, replacing them with a pleasant, harmonic white noise sound played through the ASS (Active Sound System).
[0035] The component can be an electric seat adjustment mechanism where the ANC system and active sound design can be used to reduce continuous operating noises and instead generate a more pleasant sound, for example, when the occupant operates the switch. This can generate noises such as grinding, particularly squeaking, when the seat moves along the rails of a seat mount and / or a squeaking or continuous rustling of the seat cover. These noises can be detected by interference using the ANC and reduced or eliminated by emitting an interference sound wave, as can also be done for all other embodiments described here, in order to replace them with a pleasantly perceived sound, such as harmonic white noise, via the ASS.
[0036] The component in question could be an electrically adjustable exterior mirror, where the ANC system and active sound design (via the ASS) can be used to reduce continuous operating noises and instead generate a more pleasant sound, for example, when the occupant operates the switch to extend or retract the exterior mirror. Grinding or scraping noises may occur during this process, which can be suppressed by the ANC and replaced by the ASS with a more agreeable sound, such as a continuous hum or buzz, particularly a lower-pitched tone.
[0037] The component could be an electrically adjustable steering column, where the ANC system and active sound design can be used to reduce continuous operating noises and instead generate a more pleasant sound, for example, when the occupant operates the switch, allowing the steering column to change position. In this way, a squeaking, scratching, or grinding noise can be suppressed by the ANC and replaced with a more agreeable sound, such as a continuous hum or buzz, especially a lower-pitched one.
[0038] The component could be an electrically operated glove compartment, where the ANC system and active sound design can be used to reduce continuous operating noises and instead generate a more pleasant sound, for example, when the occupant operates the switch to open or close the glove compartment. In this way, a squeaking, scratching, or grinding noise can be suppressed by the ANC and replaced with a more agreeable sound, such as a continuous hum or buzz, especially a lower-pitched one.
[0039] The component could be an electrically operated center console flap, where the ANC system and active sound design can be used to reduce continuous operating noises and instead generate a more pleasant sound, for example, when the occupant operates the switch to open or close the center console flap. In this way, a squeaking, scratching, or grinding noise can be suppressed by the ANC and replaced with a more agreeable sound, such as a continuous hum or buzz, especially a lower-pitched one.
[0040] The component can be an electrically movable screen, where the ANC system and active sound design are used to reduce continuous operating noises and instead generate a more pleasant sound, for example, when the occupant operates the switch to extend or retract the screen, perhaps from a storage cavity in a dashboard. In this process, any squeaking, scratching, or grinding noise can be suppressed by the ANC and replaced with a more agreeable sound, such as a continuous hum or buzz, particularly a lower-pitched tone.
[0041] The components described here and elsewhere can be installed in a motor vehicle and actively adjusted by the occupant. These components can be electronically operated, for example, via a switch on the center console or a door panel.
[0042] Operating the switch activates the ANC system, which reduces the continuous operating noise of the described components and simultaneously emits a predefined, high-quality sound (Active Sound Design) through a suitable loudspeaker. The described noises, which may be perceived as inferior, are merely examples. Other, particularly undesirable, noises can also be replaced by desired sounds through the active sound design.
[0043] The ANC system can incorporate various parameters, such as travel speed, direction of travel, or the specific area of noise to be reduced, just like the ASS system. Furthermore, the system(s) can also automatically react to certain conditions, such as the travel speed, direction of travel, or the specific area of noise to be reduced, when the actuator is active or when the component is moving.
[0044] From one perspective, the motor vehicle may have a computing device, trained and equipped to coordinate the ANC and the ASS, in particular to control them continuously over time.
[0045] The computing unit is, in particular, a hardware and software combination (software as a computer program product, as described elsewhere herein) specifically adapted to the requirements described here and elsewhere herein, located within the vehicle or in communicative connection with it, and designed to coordinate the functions of the ANC system and the active sound design via the ASS. The computing unit can be integrated with the relevant sensors, actuators, sound output devices for the ANC and / or the ASS, and the vehicle control system to allow the activity of both systems to overlap in time and, in particular, to control them continuously over time.
[0046] One embodiment of a computing unit in a motor vehicle can be a combination of a central processor, a signal processing system for ANC technology, and an audio database manager (on a storage device described elsewhere herein) that manages the audio files and sound profiles for playback via a loudspeaker of an audio system. The computing unit can also be connected to the respective sensors and actuators of the actuated components, such as the glove compartment or the center console flap, where the sensors can also be sound transducers, such as microphones, to capture the signal to be suppressed.In other embodiments, at least one audio file may also be provided, for example on a storage device described elsewhere herein, in order to avoid having to measure a recurring unwanted signal again each time the component is activated, but to be able to use it directly to suppress the resulting signal.
[0047] By coordinating the activity of the ANC system and the active sound design using the ASS system, a significantly improved impression of quality is achieved. The computing unit can manage various parameters such as travel speed, direction of travel, or the specific area of noise to be reduced, and can also automatically react to certain conditions, such as the travel speed, direction of travel, or the specific area of noise to be reduced by the active component.
[0048] From one perspective, an occupant's wish to activate the operating device can be determined in such a way as to prepare for the use of ANC and ASS and / or to already carry out the activation of the operating device.
[0049] To determine whether an occupant intends to activate a control device, a special device can be installed in the vehicle that analyzes the occupant's movements and predicts the probability of activation. Cameras or sensors (such as a light barrier) can be used for this purpose, for example, to track the occupant's hand movements. This data is then evaluated by the computer unit, which generates an activation signal when a certain probability threshold is reached.
[0050] Alternatively, the device can also use a switch, slider, or button that has a first pressure position. This allows an occupant's request to activate the device to be transmitted as soon as the occupant (fully) activates the switch, slider, or button.
[0051] The occupant's wish to operate the operating device refers in particular to the occupant's intention to activate a specific operating device in the vehicle, such as the window regulator or the center console flap (this also applies accordingly to the other components as described elsewhere herein).
[0052] Preparing for the deployment of the ANC and ASS includes, in particular, checking the functionality of the computing equipment and providing the necessary data and parameters for operation. This also involves monitoring and taking into account any conditions, such as travel speed, direction of travel, or the area of the active component whose noise is to be reduced.
[0053] The implementation of ANC and ASS involves, in particular, activating the technical systems to fulfill the occupant's request to operate the control device. The ANC system is activated to reduce or eliminate the noise of the actuated device, while simultaneously the active sound design is played through the speakers.
[0054] Examples of parameters for predicting an actuation request could include the probability of an actuation device being actuated, for example based on the pressure position of the switch, slider or button, or a time history of actuation, particularly in a previous behavior pattern.
[0055] From one perspective, the actuation of the operating device can be performed by the occupant. Actuation of the operating device by the occupant refers specifically to the occupant's action to activate a particular operating device (a component, as described elsewhere herein) in the vehicle. This can be done by various methods, such as pressing a switch, slider, or button.
[0056] Within the scope of the described aspects and / or embodiments, the perceived quality of the operating noise can be improved in the case of continuous operating noises in the interior and / or exterior of a motor vehicle. For this purpose, the ANC system is activated to reduce or eliminate the operating noise, while simultaneously the active sound design is played through loudspeakers.
[0057] In summary, it can be said that the occupant can activate the operating device through their action and thus trigger the use of the ANC system and the active sound design.
[0058] From an independent perspective, a process can be designed and set up to create active noise design—also known as sound design. The process may include a step of detecting a noise to be suppressed. The process may include a step of suppressing the noise to be suppressed. The process may include a step of playing back a noise to be generated.
[0059] In one embodiment, the method for designing an active sound system can be divided into several steps, such as detecting the noise to be suppressed. Special sensors or microphones can be used to measure corresponding activity or actuation noises inside and / or outside the vehicle, emanating from the component to be actuated or from its mechanism. A counter-noise can be generated from the recorded noises to cancel out or reduce the unwanted noise through interference by the ANC (Active Noise Cancellation). Furthermore, this recorded noise can be stored as information in a database for later retrieval, enabling the playback of a corresponding counter-noise for interference.
[0060] In one step of suppressing the noise to be suppressed, the ANC system can reduce or eliminate the unwanted noise in order to minimize or completely prevent the propagation of the noise in the interior and / or exterior of the vehicle.
[0061] In one step of the process of playing back a sound, a predefined sound is loaded from a database and played through the vehicle's speakers to provide the occupants with a high-quality sound experience. These sounds can be individually customized or selected for each occupant or a group of occupants. This playback step overlaps with the step of suppressing an unwanted sound (i.e., the sound to be suppressed) and with the step of activating a control device to trigger an actuator to move a component.
[0062] In one step of recognizing a desired action, a sensor can be used to detect the occupant's wish to actuate a device (e.g., the wish to press a switch to adjust one of the components described elsewhere herein). This sensor could be, for example, a light barrier. In other configurations, the device may have a pre-positioned position that can indicate a desired action. Once the desired action is recognized, the ANC system can be activated and begin reducing noise. Simultaneously, the active sound design is also activated.
[0063] This allows for an improvement in the perceived quality of sound in the vehicle's interior and / or exterior. It can reduce disruptive noise caused by the operation of electronic components, particularly noises that are potentially perceived as disturbing. It enables individual adjustment of the sound characteristics for each occupant or a group of occupants. It also offers the possibility of implementing active sound design even with continuous noises.
[0064] The process can be described by the features, properties, and advantages of the motor vehicle, the computing device, the storage device, the computer program product, and the ASS (Automated Storage System). This also applies across the category boundaries of process, device, and system. Thus, the motor vehicle, the ASS, the computing device, the storage device, and the computer program product can also be described by the features, properties, and advantages of the process. For the sake of readability and conciseness, a repetition of all these features, properties, and advantages is omitted.
[0065] From an independent perspective, an active sound system (ASS) can be designed and configured to perform a procedure as described elsewhere. The ASS can serve as an active sound design tool, particularly for the simultaneous suppression of unwanted, potentially disruptive noises. The ASS can include at least one indoor microphone and at least one loudspeaker to output a pre-recorded sound. The ASS can also include at least one computing unit and / or be communicatively connected to one to transmit recorded information, especially tones, noises, and / or continuous-time noise profiles, to it. This allows the computing unit to perform calculations based on the parameters and conditions described elsewhere, specifically to generate a counter-noise signal for output via active noise cancellation (ANC) to suppress unwanted noise.This allows a procedure, as described elsewhere, to be carried out.
[0066] The ASS (Automated System for Electronic Systems) can be described by the features, properties, and advantages of the motor vehicle, the process, the computing device, the storage device, and the computer program product. This also applies across the category boundaries of process, device, and system. Thus, the motor vehicle, the process, the computing device, the storage device, and the computer program product can also be described by the features, properties, and advantages of the ASS. For the sake of readability and conciseness, a repetition of all these features, properties, and advantages is omitted.
[0067] From an independent perspective, a computing device can be designed and configured to perform a procedure as described elsewhere. The computing device can therefore also function, at least partially, as a control unit for software components, but also for hardware components of a motor vehicle.
[0068] The computing device can be described by the features, properties, and advantages of the motor vehicle, the process, the automated storage device (ASD), the storage device, and the computer program product. This also applies across the category boundaries of process, device, and system. Thus, the motor vehicle, the process, the ASD, the storage device, and the computer program product can also be described by the features, properties, and advantages of the computing device. For the sake of readability and conciseness, a repetition of all these features, properties, and advantages is omitted.
[0069] From an independent perspective, a computer program product can be designed and configured to perform a procedure as described elsewhere when executed on a computing device, particularly as described elsewhere. In doing so, the computer program product can provide instructions when executed on the computing device as described elsewhere to enable the execution of a procedure.
[0070] The computer program product can be described by the features, properties, and advantages of the motor vehicle, the ASS (Automated System for Vehicles), the computing device, the storage device, and the process. This also applies across the category boundaries of process, device, and system. Thus, the motor vehicle, the ASS, the computing device, and the storage device can also be described by the features, properties, and advantages of the computer program product. For the sake of conciseness and readability, a repetition of all these features, properties, and advantages is omitted here.
[0071] The computer program product can be designed and configured to be executed on a machine. During execution of the computer program product on the machine, a procedure as described elsewhere can be performed. The computer program product is, in particular, machine-readable code and / or an electrical signal configured to be read by a machine in order to transmit instructions to the machine, such as to perform a procedure of the type described elsewhere. A computer program product can, in particular, be configured as machine-readable code, especially as an algorithm, capable of performing a corresponding analysis of hand positions or their changes in order to determine an action request.Alternatively or additionally, the machine-readable code can also execute instructions to make at least one adjustment to an ACN, an ASS, especially to an active sound design.
[0072] From an independent perspective, a storage facility can be designed and configured to exhibit a computer program product as described elsewhere.
[0073] A storage device can be a storage medium that may contain a computer program product as described. Alternatively or additionally, the computing device, as described, may contain a computer program product as described. The computer program product is specifically designed and configured to be read from the storage medium by the computing device in order to carry out the described procedure. Thus, the storage device and / or the computing device can be described accordingly by the features, properties, and advantages as described and explained for the procedures, the motor vehicle, the ASS (Automated System for Vehicles), and / or the computer program product. The reverse is also true. For the sake of conciseness and readability, a repetition of all these features, properties, and advantages is omitted here.
[0074] Further advantages, features, and details of the invention will become apparent from the following description, in which exemplary embodiments of the invention are described in detail with reference to the drawings. The features mentioned in the claims and in the description can be essential to the invention individually or in any combination. The drawings schematically show: Fig. 1. A representation of an embodiment of a motor vehicle, Fig. 2 a representation of an embodiment of a method.
[0075] Fig. Figure 1 shows a schematic and exemplary embodiment of a motor vehicle 10, in particular its door 15 for entering and exiting the motor vehicle 10. A window is arranged in a frame 12 as a movable component 13, which can be lowered 11a or raised 11b in a movement 11.
[0076] This is achieved in particular via an actuator, here a window regulator, which may be installed in the door panel of door 15, which is why it is not shown here. When the actuating device 14, shown here in the form of an exemplary toggle switch, information about the actuation can be transmitted to a computing unit 100 via a communication link 19, which allows a computer program product 120 stored on a memory device 110 to be executed. This computer program product 120 then provides instructions to control an active noise suppression device 16 via a communication link 17 to prevent the noise to be suppressed by emitting a counter-noise via a sound-generating device (not shown here) in order to at least partially eliminate or modify the unwanted noise through destructive interference.
[0077] Information relating to a desired sound can also be transmitted from the storage device 110 via a communication link 19 to a sound generation device 23 of an ASS in order to play a desired sound.
[0078] In this process, continuous noises can be suppressed, and a corresponding continuous noise can be played back. The actuating device 14 is typically operated by an occupant, as they wish to adjust the component to be actuated. A sensor 21, such as a light barrier, can be provided to detect when the occupant places a hand on the actuating device, thus recognizing a potential intention to actuate it. The computer can then prepare the system to activate ANC and ASS with minimal or defined time delay, thereby generating a sound that is as clearly defined as possible and perceived in relation to the activity of the component.
[0079] Fig. Figure 2 shows an exemplary and schematic embodiment of a method 200 for designing an active noise design. The step 210 involves recognizing the actuation plan (an actuation request), followed by actual actuation of the actuating device 14, exemplified as a toggle switch in the Fig. As shown in Figure 1, the following applies. This allows component 13 to proceed 230. In particular, simultaneously with a proceeding 230 of component 13, a detection 235 of a noise to be suppressed can take place in order to be able to suppress 240 the noise to be suppressed.
[0080] In alternative embodiments, pre-stored information regarding the noise to be suppressed can also be used to suppress the noise by means of interference in an ANC. These embodiments are particularly suitable for highly repetitive unwanted noises and accelerate the response to actuation of the actuating device 14.
[0081] In particular, simultaneously with the suppression of the noise to be suppressed (240), a step of playing back a noise to be generated (250) takes place. This allows for active sound design. This continues in particular until component 13 reaches an end position (260), which can lead to the termination of ANC and ASS.
[0082] The preceding explanation of the embodiments describes the present invention solely by way of examples. Naturally, individual features of the embodiments can be freely combined with one another, provided this is technically feasible, without departing from the scope of the present invention.
