Description

Technical Field

[0001] This invention relates to the field of sound data fitting and production technology, and in particular to a precise fitting and therapeutic sound generation system and method for tinnitus with multiple complaints. Background Technology

[0002] Tinnitus is a buzzing, hissing, or ringing sound perceived in the ear or skull by patients with multiple complaints of tinnitus, even without external sound stimulation. Tinnitus is a common auditory system disorder that seriously affects a person's health and quality of life. Treatment methods for patients with multiple complaints of tinnitus include notching therapy and masking therapy. Notching therapy, developed in recent years based on the central mechanism theory of tinnitus para-inhibition disorder, is a sound therapy method that mainly filters out a frequency range centered on the tinnitus center frequency f, thereby creating notched music. Stimulation by notched music can reduce the excitation of neurons at characteristic frequencies corresponding to the tinnitus center frequency, while maintaining stimulation of frequencies outside the notched frequency range. This allows the tinnitus center frequency region to receive para-inhibition, reversing adverse neural remodeling, reducing the perception of tinnitus in patients with multiple complaints of tinnitus, and achieving the effect of treating and improving tinnitus. Masking therapy is a physiological treatment method that uses external sound to reduce or eliminate tinnitus. The principle is to use broadband or narrowband noise corresponding to the damaged neurons as masking sound, thereby inhibiting the overactivation of related nerves and reducing abnormal spontaneous discharge activity, thus reducing or eliminating tinnitus.

[0003] Existing technology discloses a method for generating notched music for tinnitus treatment. This method obtains the enhanced frequency range from the center frequency of the tinnitus sound for each patient with multiple complaints of tinnitus, enhances the data in the natural sound data that falls within this enhanced frequency range, and then performs notching processing on the enhanced natural sound data to ensure personalized notched music. The notched music obtained based on this method can effectively treat both high-frequency and low-frequency tinnitus. Existing technology also discloses a method for generating therapeutic tinnitus sound based on masking and audio equalization. This method redistributes audio energy before masking the audio, ensuring that the masking sound completely masks the tinnitus sound while also being comfortable and pleasant to the ear. This improves the treatment experience and acceptance for patients with multiple complaints of tinnitus, and promotes treatment effectiveness.

[0004] However, the above methods can only treat tinnitus with a single complaint. For patients with multiple complaints of tinnitus (where a single ear has more than one tinnitus center frequency), the different frequencies of tinnitus interfere with each other. Most patients with multiple complaints cannot accurately describe their tinnitus center frequency, and even when a matching tinnitus sound is found without blocking out other tinnitus sounds, they will still feel significant tinnitus interference. Traditional fitting methods cannot accurately match tinnitus information for multiple complaints. Furthermore, these methods can only treat one tinnitus center frequency before moving on to the next, and the inability to address other tinnitus sounds during treatment itself contributes to a poor treatment experience for patients with multiple complaints. Therefore, this treatment method has a long treatment cycle, cannot treat multiple complaints simultaneously, and suffers from poor patient experience and ineffective treatment. Summary of the Invention

[0005] To address the aforementioned problems, the purpose of this invention is to provide a precise fitting and therapeutic sound generation system and method for treating multiple tinnitus complaints simultaneously.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Firstly, it provides a precise fitting and therapeutic sound generation system for multiple complaints of tinnitus, comprising:

[0007] The preliminary fitting module is used to perform preliminary fitting of all tinnitus sounds for patients with multiple complaints of tinnitus, and obtain the preliminary fitting sound for patients with multiple complaints of tinnitus.

[0008] The refined preliminary fitting module is used to apply a complete masking sound to the remaining tinnitus sounds of patients with multiple complaints of tinnitus, and to perform refined preliminary fitting on the preliminary fitting sound of the current tinnitus sound to obtain a refined preliminary fitting sound.

[0009] The data processing module is used to select a natural sound, apply the first notch processing and the second notch processing to the refined preliminary fitting sound corresponding to the current tinnitus sound, apply the first masking processing and the second masking processing to the refined preliminary fitting sounds corresponding to other tinnitus sounds, and determine the test treatment sound after the first data processing and the test treatment sound after the second data processing and their residual inhibition time difference.

[0010] The refined fitting module is used to repeatedly adjust until the residual inhibition time of the test treatment sound after the second data processing of the refined preliminary fitting sound corresponding to the current tinnitus sound is longer than that of the test treatment sound after the first data processing, and the residual inhibition time difference corresponding to the refined preliminary fitting sound is greater than the residual inhibition time difference corresponding to the adjacent fitting sound. The refined preliminary fitting sound at this time is taken as the refined fitting sound of the current tinnitus sound.

[0011] The therapeutic sound generation module is used to select a natural sound for treatment. For patients with multiple complaints of tinnitus, the refined fitting sound of each tinnitus sound is processed by the third notch or the third masking to generate a multi-tinnitus therapeutic sound for patients with multiple complaints of tinnitus.

[0012] Furthermore, the preliminary fitting of all tinnitus sounds for patients with multiple complaints of tinnitus, to obtain preliminary fitting sounds for patients with multiple complaints of tinnitus, includes:

[0013] The sound signal is given by the sound-giving device, which provides the tinnitus center frequency f, tinnitus width factor w, and tinnitus loudness s;

[0014] Repeatedly adjust the above tinnitus information to find the sound signal that is closest to the tinnitus sound of the patient with multiple complaints of tinnitus. Record the tinnitus center frequency f, tinnitus width factor w, and tinnitus loudness s at this time as the tinnitus information of the preliminary fitting sound corresponding to the current tinnitus sound of the patient with multiple complaints of tinnitus.

[0015] Repeat the above steps and perform the same procedure on patients with multiple complaints of tinnitus until the initial fitting of all the tinnitus sounds for the patients with multiple complaints of tinnitus is completed, and the tinnitus information of the initial fitting sounds corresponding to all the tinnitus sounds for the patients with multiple complaints of tinnitus is obtained.

[0016] Furthermore, the step of applying a complete masking sound to the remaining tinnitus sounds of patients with multiple complaints of tinnitus, and performing a refined preliminary fitting sound on the preliminary fitting sound of the current tinnitus sound to obtain a refined preliminary fitting sound, includes:

[0017] Apply a masking sound to the center frequency of tinnitus sounds other than the current tinnitus sound to completely mask the other tinnitus sounds;

[0018] The sound signal is provided by the sound-giving device, which includes the tinnitus center frequency f, tinnitus width factor w, and tinnitus loudness s of the current tinnitus sound;

[0019] Repeatedly adjust the above tinnitus information to find the sound signal that is closest to the tinnitus sound of patients with multiple complaints of tinnitus. Record the tinnitus center frequency f, tinnitus width factor w, and tinnitus loudness s at this time as the tinnitus information of the refined preliminary fitting sound corresponding to the current tinnitus sound of patients with multiple complaints of tinnitus.

[0020] Further, the first notching process includes a first enhancement process and a first filtering process for the audio; the first enhancement process enhances the spectral energy of a frequency range with a width factor of wz1i centered on the tinnitus center frequency fi in the tinnitus information Ti corresponding to the refined preliminary fitting sound of the tinnitus sound to an enhancement intensity; the first filtering process reduces the spectral energy of a frequency range with a width factor of wb1i centered on the tinnitus center frequency fi in the tinnitus information Ti corresponding to the refined preliminary fitting sound of the tinnitus sound to a filtering intensity, where wz1i is the enhancement width factor corresponding to the first enhancement frequency range of the i-th tinnitus information; and wb1i is the filtering width factor corresponding to the first filtering frequency range of the i-th tinnitus information.

[0021] The second notching process includes a second enhancement process and a second filtering process for the audio. The second enhancement process enhances the spectral energy of a second enhancement frequency interval with a width factor of wz2i centered on the tinnitus center frequency fi in the tinnitus information Ti corresponding to the refined preliminary fitting sound of the tinnitus sound to the enhancement intensity. The second filtering process reduces the spectral energy of a second filtering frequency interval with a width factor of wb12 centered on the tinnitus center frequency fi in the tinnitus information Ti corresponding to the refined preliminary fitting sound of the tinnitus sound to the filtering intensity. Here, wz2i is the enhancement width factor corresponding to the second enhancement frequency interval of the i-th tinnitus information, and wb2i is the filtering width factor corresponding to the second filtering frequency interval of the i-th tinnitus information.

[0022] Furthermore, the method for confirming the frequency range in the first notch processing is as follows:

[0023] The first enhancement frequency range fz is defined as (fl1, fu1), where fl1 <fz<fu1;

[0024] Let the first filtering frequency interval fb be (fl2, fu2), then fl1 <fl2<fb<fu2<fu1;

[0025] The first enhanced frequency range and the first notch frequency range satisfy the following relationship:

[0026] fl1 = f / wz1

[0027] fu1=f*wz1

[0028] fl2 = f / wb1

[0029] fu2=f*wb1

[0030] Where wz1 is the enhancement width factor corresponding to the first enhancement frequency range; wb1 is the filter width factor corresponding to the first filter frequency range.

[0031] Furthermore, the first masking process is to use masking sound superposition or enhancement to masking intensity on a first masking frequency interval with a width factor of wy1i centered on the tinnitus center frequency fi in the tinnitus information Ti corresponding to the refined preliminary fitting sound of the tinnitus sound, where wy1i is the masking width factor corresponding to the masking frequency interval of the i-th tinnitus information.

[0032] The second masking process involves using masking sounds to superimpose or enhance a second masking frequency range with a width factor of wy2i, centered on the tinnitus center frequency fi in the tinnitus information Ti corresponding to the refined preliminary fitting sound, to achieve masking intensity.

[0033] Furthermore, the method for confirming the first masking frequency range is as follows:

[0034] The masking frequency fy is set to the interval (fl3, fu3), where fl3 <fy<fu3;

[0035] The masking frequency range simultaneously satisfies the following relationship:

[0036] fl3 = f / wy1

[0037] fu3=f*wy1

[0038] Where wy1 is the masking width factor corresponding to the masking frequency range.

[0039] Secondly, it provides a precise fitting and therapeutic sound generation method for tinnitus with multiple complaints, including:

[0040] A preliminary fitting was performed on all tinnitus sounds of patients with multiple complaints of tinnitus, and the preliminary fitting sound of patients with multiple complaints of tinnitus was obtained.

[0041] A complete masking sound is applied to the remaining tinnitus sounds of patients with multiple complaints of tinnitus, and a refined preliminary fitting sound is performed on the preliminary fitting sound of the current tinnitus sound to obtain a refined preliminary fitting sound.

[0042] Select a natural sound, apply the first notch processing and the second notch processing to the refined preliminary fitting sound corresponding to the current tinnitus sound respectively, apply the first masking processing and the second masking processing to the refined preliminary fitting sounds corresponding to other tinnitus sounds respectively, and determine the test treatment sound after the first data processing and the test treatment sound after the second data processing and their residual inhibition time difference.

[0043] Repeat the adjustment until the residual inhibition time of the test treatment sound after the second data processing of the refined preliminary fitting sound corresponding to the current tinnitus sound is longer than that of the test treatment sound after the first data processing, and the residual inhibition time difference corresponding to the refined preliminary fitting sound is greater than the residual inhibition time difference corresponding to the adjacent fitting sound. Then, take the refined preliminary fitting sound at this time as the refined fitting sound of the current tinnitus sound.

[0044] A natural sound for treatment is selected, and the refined matching sound of each tinnitus sound for patients with multiple complaints of tinnitus is processed with the third notch or the third masking to generate a multi-tinnitus treatment sound for patients with multiple complaints of tinnitus.

[0045] Thirdly, a processing device is provided, including computer program instructions, wherein when the computer program instructions are executed by the processing device, they are used to implement the steps corresponding to the above-mentioned method for accurate fitting and therapeutic sound generation of multi-complaint tinnitus.

[0046] Fourthly, a computer-readable storage medium is provided, wherein computer program instructions are stored on the computer-readable storage medium, wherein the computer program instructions, when executed by a processor, are used to implement the steps corresponding to the above-mentioned method for accurate fitting and therapeutic sound generation of multi-complaint tinnitus.

[0047] The present invention has the following advantages due to the adoption of the above technical solutions:

[0048] 1. This invention targets each patient with multiple tinnitus complaints. First, it initially obtains tinnitus information from multiple tinnitus sounds, then iterates and verifies repeatedly to obtain refined fitting results. Finally, based on the refined fitting results, it generates therapeutic sounds suitable for patients with multiple tinnitus complaints. The therapeutic sounds obtained based on this invention can provide a more comfortable and effective treatment for patients with multiple tinnitus complaints.

[0049] 2. This invention can improve fitting accuracy: The single-ear tinnitus treatment sound generation algorithm does not consider the interference between multiple tinnitus symptoms in patients with multiple complaints of tinnitus. Under traditional fitting methods, such patients with multiple complaints of tinnitus cannot be accurately matched to the accurate tinnitus center frequency. However, the method of this invention adopts the traditional approach of first measuring the rough range of tinnitus information one by one, and then performing fine fitting. In fine fitting, each tinnitus sound is fitted one by one. First, other tinnitus sounds are masked with masking sounds, and then the current tinnitus sound is finely fitted. After the fitting is completed, test treatment sounds with different intensities based on the results are generated. The point where the tinnitus sound is reduced most significantly for patients with multiple complaints of tinnitus is the fitted treatment sound. Through this initial fitting + fine fitting + feedback method, the fitting accuracy can be greatly improved.

[0050] 3. This invention can shorten the treatment cycle: Single-ear tinnitus treatment sound generation methods can only generate a treatment sound for one tinnitus center frequency at a time, and the treatment of one tinnitus center frequency must be completed before moving on to the next, which is time-consuming. However, this invention can generate a single treatment sound audio frequency based on all the tinnitus complaint information of patients with multiple complaints, achieving simultaneous treatment of all complaints of tinnitus. In this way, patients with multiple complaints of tinnitus can receive comprehensive treatment at the same time, greatly shortening the treatment time.

[0051] 4. This invention can improve treatment efficacy: For patients with multiple complaints of tinnitus, single-ear tinnitus treatment sound generation methods may not be able to effectively eliminate other tinnitus sounds when treating a certain tinnitus center frequency, thus failing to eliminate the unpleasantness caused by tinnitus and affecting the treatment experience and efficacy of patients with multiple complaints of tinnitus. However, this invention can comprehensively consider all the tinnitus information of patients with multiple complaints of tinnitus, while filtering out and enhancing signals at all tinnitus center frequencies, effectively handling the situation of multiple complaints of tinnitus, allowing patients with multiple complaints of tinnitus to have a better treatment experience and ensuring treatment efficacy.

[0052] In summary, this invention can be widely applied in the field of sound data matching and production technology. Attached Figure Description

[0061] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0062] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting.

It should also be understood that additional or alternative steps may be used.

[0063] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another.

Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0064] like Figure 1 The diagram shown illustrates the fitting results of the traditional fitting method. It can be seen that without precise fitting, the actual fitting sound deviates from the tinnitus sound due to mutual interference between multiple tinnitus sounds.

[0065] This invention provides a precise fitting and therapeutic sound generation system and method for multi-complaint tinnitus. For patients with multi-complaint tinnitus, it obtains the most accurate possible multi-tinnitus fitting information through initial fitting, fine fitting, and verification. This information is then combined with the multi-complaint tinnitus information to generate a therapeutic sound audio track, which can simultaneously treat multiple tinnitus center frequencies. In this patented technical solution, firstly, the approximate information of multiple tinnitus sounds in the patient with multi-complaint tinnitus is initially fitted. Based on this, masking sounds are applied to other tinnitus sounds one by one to finely fit the current tinnitus information. Then, through two processing steps with different notch widths, the patient with multi-complaint tinnitus verifies the accuracy of the fitting in natural sound. This method allows for precise fitting of multiple tinnitus information, which is then used as a basis to generate notched or masked multi-tinnitus therapeutic music. The advantage of this invention is that it finely fits multiple tinnitus sounds in patients with multi-complaint tinnitus, and through notching or masking processing of natural sound data, obtains personalized multi-tinnitus therapeutic music. The therapeutic music generated based on this patented method can provide a more comfortable and effective treatment effect when treating patients with multi-complaint tinnitus. This method overcomes the limitations of traditional tinnitus fitting methods, which are inaccurate for patients with multiple tinnitus symptoms and multiple complaints, and the limitations of therapeutic sound generation methods, which cannot treat patients with multiple complaints of tinnitus simultaneously.

[0066] It should be noted that the tinnitus sound mentioned in this invention refers to the sound subjectively perceived by the patient, and the fitting sound refers to the sound found through the sound matching method of this invention that is consistent with the patient's tinnitus sound perception. Both the fitting sound and the tinnitus sound are pure tones or white noise with a certain frequency, loudness, and width. The test treatment sound is a natural sound processed by the first or second data and is used to verify whether the refined fitting sound is accurate. The multi-tinnitus treatment sound is based on multi-tinnitus fitting information and natural sound data is processed by notching or masking to obtain personalized multi-tinnitus treatment music.

[0067] Example 1

[0068] like Figure 2 As shown, this embodiment provides a method for accurate fitting and therapeutic sound generation for tinnitus with multiple complaints, including the following steps:

[0069] 1) A preliminary fitting of all tinnitus sounds was performed on all patients with multiple complaints of tinnitus, resulting in the preliminary fitting sound for these patients. Specifically:

[0070] 1.1) Use a sound-generating device to provide an acoustic signal with the tinnitus center frequency f (Hz), tinnitus width factor w, and tinnitus loudness s (dB).

[0071] Specifically, the tinnitus information T includes the tinnitus center frequency f, the tinnitus width factor w, and the tinnitus loudness s, wherein the tinnitus center frequency f is the midpoint of the perceptually perceived frequency of the tinnitus sound of a patient with multiple primary tinnitus on the frequency spectrum; the tinnitus width factor w is the ratio of the upper frequency limit to the lower frequency limit on the frequency spectrum of an external narrow-band noise that is subjectively perceived by the patient with multiple primary tinnitus as equivalent to their tinnitus; and the tinnitus loudness s is the volume of an external sound that is subjectively perceived by the patient with multiple primary tinnitus as equivalent to their tinnitus.

[0072] Specifically, existing tinnitus detection equipment can be used to determine the tinnitus center frequency f, tinnitus width factor w and tinnitus loudness s of the tinnitus sound of patients with multiple primary tinnitus.

[0073] 1.2) Repeatedly adjust the above tinnitus information to find the acoustic signal closest to the tinnitus sound of the patient with multiple primary tinnitus, and record the tinnitus center frequency f, tinnitus width factor w and tinnitus loudness s at this time, which are used as the tinnitus information of the preliminary fitting sound corresponding to the current tinnitus sound of the patient with multiple primary tinnitus.

[0074] 1.3) Repeat steps 1.1) to 1.2), repeatedly perform the operation on the patient with multiple primary tinnitus in this manner until the preliminary fitting of all primary tinnitus sounds of the patient with multiple primary tinnitus is completed, and obtain the tinnitus information Ti = T1, T2...Tn of the preliminary fitting sounds corresponding to all primary tinnitus sounds of the patient with multiple primary tinnitus, where Tn is the tinnitus information of the preliminary fitting sound corresponding to the n-th tinnitus sound.

[0075] 2) Apply a complete masking sound to the remaining tinnitus sounds of the patient with multiple primary tinnitus, and perform refined preliminary fitting on the preliminary fitting sound of the current tinnitus sound to obtain a refined preliminary fitting sound, specifically as follows:

[0076] 2.1) Apply a masking sound to the tinnitus center frequencies of the other n-1 tinnitus sounds except the current tinnitus sound, so as to completely mask the other n-1 tinnitus sounds.

[0077] Specifically, the masking sound is a segment of white noise centered on the tinnitus center frequency fi, with a width of k*wi and an intensity of si+a, wherein k is a width coefficient, a is a sound intensity gain parameter, and fi, wi and si are the tinnitus center frequency, tinnitus width factor and tinnitus loudness of the i-th tinnitus information Ti.

[0078] In specific implementation, the width coefficient satisfies 1<k<3, and the sound intensity gain parameter a is generally not less than 15 dB. After applying the masking sound, the patient with multiple primary tinnitus can focus more on the fitting of the current tinnitus sound, thereby improving the fitting accuracy.

[0079] 2.2) Use a sound generating device to output an acoustic signal with the tinnitus center frequency f, tinnitus width factor w and tinnitus loudness s corresponding to the current tinnitus sound.

[0080] 2.3) Repeatedly adjust the above tinnitus information to find the acoustic signal closest to the tinnitus sound of a patient with multiple chief complaints of tinnitus, and record the tinnitus center frequency f, tinnitus width factor w and tinnitus loudness s at this time, which are used as the tinnitus information of the refined preliminary fitting sound corresponding to the current tinnitus sound of the patient with multiple chief complaints of tinnitus.

[0081] Specifically, as Figure 3 shows, when finely fitting low-frequency tinnitus, a masking sound is first applied to the high-frequency tinnitus, and then the fitting sound is made to overlap with the tinnitus sound as much as possible.

[0082] 3) Select a natural sound, perform a first notch processing with a relatively wide width and relatively weak intensity on the refined preliminary fitting sound corresponding to the current tinnitus sound, and perform a strong first masking processing on the refined preliminary fitting sounds corresponding to the other n-1 tinnitus sounds except the current tinnitus sound, so as to obtain a test and treatment sound after first data processing, which is specifically as follows:

[0083] 3.1) Select a natural sound, and perform the first notch processing with a relatively wide width and relatively weak intensity on the refined preliminary fitting sound corresponding to the current tinnitus sound.

[0084] Specifically, a sound can be specially selected as the natural sound from the existing natural sound audio library. For the selection of the natural sound, it is only required to select a sound with good subjective hearing from the natural sound audio library and adjust its playback volume to a comfortable value. In specific implementation, artificially synthesized sounds such as white noise and speech noise can also be selected according to the actual situation of the patient with multiple chief complaints of tinnitus.

[0085] Specifically, the first notch processing includes first enhancement processing and first filtering processing on the audio. The first enhancement processing is to enhance the spectral energy of a frequency interval with a width factor of wz1i centered on the tinnitus center frequency fi in the tinnitus information Ti of the refined preliminary fitting sound corresponding to the tinnitus to an enhancement intensity. The first filtering processing is to reduce the spectral energy of a frequency interval with a width factor of wb1i centered on the tinnitus center frequency fi in the tinnitus information Ti of the refined preliminary fitting sound corresponding to the tinnitus to a filtering intensity, wherein wz1i is the enhancement width factor corresponding to the first enhancement frequency interval of the i-th tinnitus information, and wz1i=n1*wi; wb1i is the filtering width factor corresponding to the first filtering frequency interval of the i-th tinnitus information, and wb1i=n2*wi, n1 and n2 are corresponding frequency expansion values, both n1 and n2 are positive numbers and 0.1<n2<n1<10. As Figure 4 shows, it is a schematic diagram of applying the wide and weak first notch processing to the finely fitted sound corresponding to low-frequency tinnitus and applying the first masking processing to the finely fitted sound corresponding to high-frequency tinnitus.

[0086] More specifically, the absolute value of the difference between the enhancement intensity and the tinnitus loudness si of the tinnitus information Ti generally does not exceed the intensity threshold of 5dB in this step; after filtering, the frequency spectrum of this interval is reduced to 0dB.

[0087] Specifically, the method for determining the frequency interval in the first notch processing is as follows:

[0088] ① Set the first enhanced frequency fz interval as (fl1, fu1), where fl1 < fz < fu1.

[0089] ② Set the first filtering frequency fb interval as (fl2, fu2), then fl1 < fl2 < fb < fu2 < fu1.

[0090] ③ The first enhanced frequency interval and the first notch frequency interval satisfy the following relationship:

[0091] fl1 = f / wz1 (1)

[0092] fu1 = f*wz1 (2)

[0093] fl2 = f / wb1 (3)

[0094] fu2 = f*wb1 (4)

[0095] Wherein, wz1 is the enhancement width factor corresponding to the first enhanced frequency interval, and wz1 = n1*w; wb1 is the filtering width factor corresponding to the first filtering frequency interval, and wb1 = n2*w.

[0096] 3.2) Performing enhanced first masking processing on the refined preliminary fitted sounds corresponding to the other n-1 tinnitus sounds except the current tinnitus sound, to obtain the test and treatment sound after first data processing.

[0097] Specifically, the first masking processing refers to superimposing or enhancing the masking sound to the masking intensity for a first masking frequency interval with a width factor wy1i centered on the tinnitus center frequency fi in the tinnitus information Ti of the refined preliminary fitted sound corresponding to the tinnitus sound, wherein wy1i is the masking width factor corresponding to the masking frequency interval of the i-th tinnitus information, and wy1i = n3*wi, n3 is the corresponding frequency expansion value, n3 is a positive number and 0.1 < n3 < 10; the absolute value of the difference between the masking intensity and the tinnitus loudness si in the tinnitus information Ti generally does not exceed the intensity threshold of 20dB in this step.

[0098] Specifically, the masking sound can be white noise or the spectrum information of the natural sound in the masking interval.

[0099] Specifically, the method for determining the first masking frequency interval is as follows:

[0100] ① Set the masking frequency fy interval as (fl3, fu3), where fl3 <fy<fu3。

[0101] ②The masking frequency range simultaneously satisfies the following relationship:

[0102] fl3=f / wy1(5)

[0103] fu3=f*wy1(6)

[0104] Where wy1 is the masking width factor corresponding to the masking frequency range, and wy1=n3*w.

[0105] 4) Using the selected natural sound, apply a narrow-width and high-intensity second notch processing to the refined preliminary fitting sound corresponding to the current tinnitus sound, and apply an enhanced second masking processing to the refined preliminary fitting sounds corresponding to the other n-1 tinnitus sounds besides the current tinnitus sound, to obtain the test treatment sound after the second data processing, specifically:

[0106] 4.1) Using the selected natural sound, apply a narrow and strong second notch to the refined preliminary fitting sound corresponding to the current tinnitus sound.

[0107] Specifically, the second notching process includes a second enhancement process and a second filtering process for the audio. The second enhancement process amplifies the spectral energy of a second enhancement frequency interval with a width factor of wz2i, centered on the tinnitus center frequency fi in the tinnitus information Ti corresponding to the refined preliminary fitting sound, to an enhancement strength. The second filtering process reduces the spectral energy of a second filtering frequency interval with a width factor of wb12, centered on the tinnitus center frequency fi in the tinnitus information Ti corresponding to the refined preliminary fitting sound, to a filtering strength, where wz2i is the enhancement width factor corresponding to the second enhancement frequency interval of the i-th tinnitus information, and wb2i is the filtering width factor corresponding to the second filtering frequency interval of the i-th tinnitus information. Figure 5 The diagram shows a process of applying a narrow and strong second notch to the fine fitting sound corresponding to low-frequency tinnitus, and applying a second masking process to the fine fitting sound corresponding to high-frequency tinnitus.

[0108] More specifically, the absolute value of the difference between the enhancement intensity and the tinnitus intensity si of the tinnitus information Ti is generally not less than the intensity threshold of 15dB in this step; after filtering, the spectrum in this interval drops to 0dB.

[0109] Specifically, the method for determining the frequency range in the second notch processing is the same as in step 3), the difference being that the frequency expansion value in this step is smaller than that in step 3). Let the frequency expansion values ​​at this time be n1' and n2', then:

[0110] n1' = k*n1 (7)

[0111] n2'=k*n2(8)

[0112] Wherein, the parameter k takes the value of 1 / 6 <k<1 / 2。

[0113] 4.2) Apply enhanced second masking processing to the refined preliminary fitting sounds corresponding to the n-1 tinnitus sounds other than the current tinnitus sound to obtain the test treatment sound after second data processing.

[0114] Specifically, the second masking process involves superimposing or enhancing a masking sound onto a second masking frequency range with a width factor of wy2i, centered on the tinnitus center frequency fi in the tinnitus information Ti corresponding to the refined preliminary fitting sound, to achieve a masking intensity. In this step, the absolute value of the difference between the masking intensity and the tinnitus loudness si in the tinnitus information Ti generally does not exceed the intensity threshold of 20dB.

[0115] Specifically, the confirmation method for the second masking frequency range is the same as that for the first masking frequency range.

[0116] 5) Determine the residual suppression time difference between the second data-processed test treatment sound and the first data-processed test treatment sound corresponding to the current tinnitus sound.

[0117] 6) Repeat steps 2) to 5) to adjust the initial fitting sound for patients with multiple complaints of tinnitus to obtain a refined initial fitting sound, until the residual inhibition time of the test treatment sound after the second data processing of the refined initial fitting sound corresponding to the current tinnitus sound is longer than that of the test treatment sound after the first data processing, and the residual inhibition time difference corresponding to the refined initial fitting sound is greater than the residual inhibition time difference corresponding to the adjacent fitting sound. The refined initial fitting sound at this time is taken as the refined fitting sound of the current tinnitus sound.

[0118] Specifically, residual inhibition refers to the temporary suppression of tinnitus after the treatment sound ends. The residual inhibition time is calculated from the end of the treatment sound until the patient hears the tinnitus sound again and it returns to its original level. The longer the residual inhibition time, the more significant the effect of the treatment sound.

[0119] Specifically, if the fitting is most accurate, patients with multiple complaints of tinnitus should be able to feel that their own tinnitus is removed to the greatest extent from the perceptual audio generated from step 3) to step 4). Any deviation will weaken this perception. Therefore, when patients with multiple complaints of tinnitus are fitted with a certain fitting center frequency during refined fitting, they should then perceive the treatment sound of the adjacent fitting center frequency. If neither audio is as significantly effective as the current audio in removing tinnitus, it indicates that the fitting is accurate.

[0120] like Figure 6 As shown, the frequency of left and right adjustment is generated for the current refined fitting sound. Figure 6 (a) Figure 6 (b) and Figure 6 (c) Figure 6 (d) Compare the two sets of fitting audio with the previous ones. If the residual suppression of tinnitus by these test treatment sounds is lower than that in steps 3) and 4), it means that the refined fitting sound is equal to the tinnitus sound, and the refined fitting of the tinnitus is completed. That is: if the refined fitting sound is accurate at this time (the refined fitting sound is equal to the tinnitus sound), then the narrow notch generated by the refined fitting sound will have the most significant effect on the patient when the treatment is a wider notch (the time difference is the largest in terms of residual suppression). If the refined fitting sound is inaccurate, it is similar to an upward convex quadratic function. Only when the position of the refined fitting sound is accurate is it at the vertex. If the left and right adjustment frequencies are both smaller than the values ​​measured by the refined fitting sound, it means that the refined fitting sound is accurate. If one is worse than the refined fitting sound and the other is better than the refined fitting sound, it means that the tinnitus sound is better on the side after the refined fitting sound is moved.

[0121] 7) Proceed to step 2) Process the other n-1 tinnitus sounds to obtain the corresponding refined fitting sounds, and obtain the tinnitus information Ti of the final refined fitting sounds for patients with multiple complaints of tinnitus.

[0122] 8) Select a natural sound for treatment, and perform third notching or third masking processing on the refined matching sound of each tinnitus sound for patients with multiple complaints of tinnitus, to generate a multi-tinnitus treatment sound for patients with multiple complaints of tinnitus.

[0123] Specifically, the third notching process includes a third enhancement process and a third filtering process for the audio. The third enhancement process increases the spectral energy of a third enhancement frequency interval with a width factor of wz3i, centered on the tinnitus center frequency fi in the refined fitting sound of the tinnitus sound Ti, to an enhancement intensity. The third filtering process reduces the spectral energy of a third filtering frequency interval with a width factor of wb3i, centered on the tinnitus center frequency fi in the refined fitting sound of the tinnitus sound Ti, to a filtering intensity of 0dB, where wz3i is the enhancement width factor corresponding to the third enhancement frequency interval of the i-th tinnitus information; and wb3i is the notch width corresponding to the third filtering frequency interval of the i-th tinnitus information.

[0124] Specifically, the third masking process involves superimposing or enhancing a masking sound onto a third frequency range with a width factor of wy3i, centered on the tinnitus center frequency fi in the tinnitus information Ti of the refined fitting sound of the tinnitus sound, to achieve a masking intensity. The absolute value of the difference between the masking intensity and the tinnitus loudness si in the tinnitus information Ti of the refined fitting sound of the tinnitus sound generally does not exceed the intensity threshold of 20dB in this step.

[0125] like Figure 7The diagram shown illustrates the generation of therapeutic sounds for tinnitus. Figure 7 (a) is the therapeutic audio for notch processing. Figure 7 (b) is the treatment audio for masking.

The refined preliminary fitting sound at this time is then used as the refined fitting sound of the current tinnitus sound.

[0132] The therapeutic sound generation module is used to select a natural sound for treatment. For patients with multiple complaints of tinnitus, the refined fitting sound of each tinnitus sound is processed by the third notch or the third masking to generate a multi-tinnitus therapeutic sound for patients with multiple complaints of tinnitus.

[0142] The second notching process includes a second enhancement process and a second filtering process for the audio. The second enhancement process enhances the spectral energy of a second enhancement frequency interval with a width factor of wz2i, centered on the tinnitus center frequency fi in the tinnitus information Ti corresponding to the refined preliminary fitting sound, to the enhancement strength. The second filtering process reduces the spectral energy of a second filtering frequency interval with a width factor of wb12, centered on the tinnitus center frequency fi in the tinnitus information Ti corresponding to the refined preliminary fitting sound, to the filtering strength. Here, wz2i is the enhancement width factor corresponding to the second enhancement frequency interval of the i-th tinnitus information, and wb2i is the filtering width factor corresponding to the second filtering frequency interval of the i-th tinnitus information.
