Description

Technical Field

[0001] This invention relates to the field of audio loudness compensation technology, and in particular to a method and system for compensating for the loudness energy of therapeutic audio frequencies in cases of tinnitus and hearing loss. Background Technology

[0002] Tinnitus is a subjective sound sensation in the ear or skull without external sound or electrical stimulation. Compared to other treatments such as drug intervention and transcranial magnetic stimulation, sound therapy, which is safer and more effective, is widely recommended and used in tinnitus intervention management and clinical treatment. Sound therapy uses specific sounds (such as pure tones, narrowband noise, white noise, or music) to reduce the patient's ability to distinguish and perceive tinnitus, thereby reducing the psychological stress or negative emotions caused by tinnitus.

[0003] Patients with tinnitus and hearing loss coexisting are those who also experience some degree of hearing loss. Hearing loss causes significant differences in audiological parameters such as hearing threshold and loudness curves between these patients and those with normal hearing. This leads to different auditory perceptions of the same therapeutic sounds and consequently, differences in treatment effectiveness. Existing algorithms for generating or modifying tinnitus therapeutic sounds often ignore these differences in hearing levels. More seriously, because patients with tinnitus and hearing loss also experience varying degrees of hearing loss in other frequency bands, most existing algorithms only focus on loudness processing at the tinnitus frequency, neglecting the configuration and compensation of therapeutic sounds in other frequency bands. This often results in auditory discomfort or poor treatment outcomes for patients with tinnitus and hearing loss. Specifically, in frequency bands with lower hearing thresholds, the perceived loudness of the therapeutic sound is too high, causing discomfort or even approaching the pain threshold; in frequency bands with higher hearing thresholds, the perceived loudness is too low, leading to poor treatment efficacy.

[0004] Because existing tinnitus treatment sound generation or modification schemes ignore the differences in hearing status and treatment sound perception between patients with tinnitus and hearing loss and those with normal hearing, it is difficult to balance the treatment effect and comfort of patients with tinnitus and hearing loss. Therefore, it is necessary to propose an optimized tinnitus treatment sound scheme for patients with tinnitus and hearing loss. Summary of the Invention

[0005] To address the aforementioned problems, the purpose of this invention is to provide a method and system for compensating for the sound energy of coexisting tinnitus and hearing loss, which can improve the effectiveness and comfort of sound therapy for patients with coexisting tinnitus and hearing loss.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Firstly, it provides a method for compensating for the loudness energy of sound frequencies in the treatment of tinnitus and hearing loss, comprising:

[0007] To obtain tinnitus parameters and tinnitus hearing thresholds in patients with tinnitus and hearing loss, and to determine the relative sound pressure level of tinnitus at the tinnitus frequency in these patients;

[0008] Measure the pure tone sound pressure level required to maintain the tinnitus sound at the same loudness level in patients with tinnitus and hearing loss, and generate tinnitus sound equal-loudness curves;

[0009] Determine the normal hearing threshold at the tinnitus frequency in individuals with normal hearing compared to patients with tinnitus and hearing loss;

[0010] Determine the pure-tone equal-loudness curve for individuals with normal hearing based on the relative sound pressure level of tinnitus and the normal hearing threshold;

[0011] The sound pressure difference to be compensated is calculated based on the tinnitus sound equal loudness curve, the pure tone equal loudness curve of a person with normal hearing, the tinnitus hearing threshold and the normal hearing threshold.

[0012] For tinnitus treatment sound signals, audio loudness energy compensation processing is performed based on the sound pressure difference to be compensated in each frequency band.

[0013] Further, the step of acquiring tinnitus parameters and tinnitus hearing thresholds in patients with coexisting tinnitus and hearing loss, and determining the relative sound pressure level of tinnitus at the tinnitus frequency in these patients, includes:

[0014] The tinnitus parameters and tinnitus hearing threshold of patients with tinnitus and hearing loss are obtained. The tinnitus parameters include tinnitus frequency and tinnitus sound pressure level. Tinnitus frequency is the tinnitus center frequency, tinnitus sound pressure level is the tinnitus sound intensity of the patient quantified by sound pressure level as a physical quantity, and tinnitus hearing threshold is the hearing threshold of the patient at the tinnitus frequency.

[0015] Using the tinnitus hearing threshold of patients with tinnitus and hearing loss as a baseline, the difference between the tinnitus sound pressure level at the tinnitus frequency and the tinnitus hearing threshold is calculated to obtain the relative tinnitus sound pressure level of patients with tinnitus and hearing loss at the tinnitus hearing threshold.

[0016] Further, the measurement of the pure-tone sound pressure level required to maintain the tinnitus sound at equal loudness in patients with tinnitus and hearing loss, and the generation of the tinnitus sound equal loudness curve, includes:

[0017] Under the condition of keeping the loudness of tinnitus the same for patients with tinnitus and hearing loss, the equivalent pure tone of the tinnitus sound is measured at N frequency points.

[0018] By using an interpolation method, M internal frequency points are inserted into each segment of the measured frequency points and equal loudness sound pressure level data to generate a data pair mapping relationship sequence consisting of ((N-1)×(M+1)+1) pairs of "frequency points and equal loudness sound pressure levels", thereby determining the equal loudness curve of tinnitus.

[0019] Furthermore, determining the normal hearing threshold at the tinnitus frequency in a patient with tinnitus and hearing loss who also has tinnitus includes:

[0020] Determine the equal loudness curves for individuals with normal hearing based on general acoustic standards;

[0021] Based on the equal loudness curve of a person with normal hearing, the sound pressure level at the tinnitus frequency is calculated as the normal hearing threshold.

[0022] Furthermore, determining the pure-tone equal-loudness curve for a person with normal hearing based on the relative sound pressure level of tinnitus and the normal hearing threshold includes:

[0023] Based on the same general acoustic standard used to determine the equal loudness curves of people with normal hearing, the loudness level and the pure tone equal loudness curves of people with normal hearing are determined to satisfy the condition that the relative sound pressure level of tinnitus is m at the tinnitus frequency. Here, m is the relative sound pressure level of tinnitus at the tinnitus frequency for patients with tinnitus and hearing loss.

[0024] Further, the step of calculating the sound pressure difference to be compensated based on the tinnitus sound equal-loudness curve, the pure-tone equal-loudness curve of a person with normal hearing, the tinnitus hearing threshold, and the normal hearing threshold includes:

[0025] Based on the tinnitus hearing threshold of patients with tinnitus and hearing loss and the normal hearing threshold of normal hearing individuals at the tinnitus frequency of patients with tinnitus and hearing loss, the hearing threshold difference between patients with tinnitus and hearing loss and normal hearing individuals at the tinnitus frequency is determined.

[0026] Using the pure tone equal loudness curve of a person with normal hearing as a reference template, the part that needs to be reduced to equal loudness in the tinnitus equal loudness curve is determined according to the difference in hearing threshold, and the shifted tinnitus equal loudness curve is obtained.

[0027] The shifted tinnitus equal loudness curve is compared with the pure tone equal loudness curve of a person with normal hearing. The interval between the two curves is the sound pressure difference to be compensated during equal loudness adjustment.

[0028] Furthermore, the sound pressure difference D to be compensated f for:

[0029] D f =A nf -A′ f

[0030] In the formula, A nf A′ represents the sound pressure level at each frequency point on the pure-tone equal loudness curve for individuals with normal hearing. f Let be the sound pressure level at each frequency point on the shifted tinnitus sound equal loudness curve, and:

[0031] A′ f =A f -l

[0032] In the formula, A f Let l be the equivalent pure tone of the tinnitus sound at N frequency points, and l be the hearing threshold difference.

[0033] Secondly, a therapeutic sound level and other loudness energy compensation system for tinnitus and hearing loss is provided, including:

[0034] The tinnitus relative sound pressure level determination module is used to obtain the tinnitus parameters and tinnitus hearing threshold of patients with tinnitus and hearing loss, and to determine the tinnitus relative sound pressure level of patients with tinnitus and hearing loss at the tinnitus frequency;

[0035] The tinnitus sound equal-loudness curve determination module is used to measure the pure tone sound pressure level required to maintain the tinnitus sound equal-loudness in patients with tinnitus and hearing loss, and to generate the tinnitus sound equal-loudness curve.

[0036] The normal hearing threshold determination module is used to determine the normal hearing threshold of a person with normal hearing at the tinnitus frequency in a patient with tinnitus and hearing loss.

[0037] The module for determining the pure tone equal loudness curve of a person with normal hearing is used to determine the pure tone equal loudness curve of a person with normal hearing based on the relative sound pressure level of tinnitus and the normal hearing threshold.

[0038] The sound pressure difference determination module is used to calculate the sound pressure difference to be compensated based on the tinnitus sound equal loudness curve, the pure tone equal loudness curve of a person with normal hearing, the tinnitus hearing threshold and the normal hearing threshold.

[0039] The audio loudness energy compensation processing module is used to perform audio loudness energy compensation processing on the tinnitus treatment sound signal based on the sound pressure difference to be compensated in each frequency band.

[0040] 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 treatment method for sound and noise energy compensation for tinnitus and hearing loss.

[0041] 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-described treatment method for sound and noise energy compensation for tinnitus and hearing loss.

[0042] The present invention has the following advantages due to the adoption of the above technical solutions:

[0043] 1. This invention precisely corrects the energy of each frequency band of audio based on parameters such as tinnitus parameters and hearing equal-loudness curves, so that the auditory center of tinnitus patients with hearing loss perceives the therapeutic sound in the same way as people with normal hearing perceive the tinnitus therapeutic sound, reducing the negative impact of hearing loss on the treatment effect and comfort, and ensuring the therapeutic effect of tinnitus sound therapy.

[0044] 2. This invention takes into account both hearing loss and tinnitus in patients with coexisting tinnitus and hearing loss. It considers and compensates for the difference in the perception of therapeutic sounds between deaf patients and those with normal hearing, thereby reducing the negative impact of hearing loss on the treatment effect and experience of tinnitus and improving the treatment comfort of patients with coexisting tinnitus and hearing loss.

[0045] In summary, this invention can be widely applied in the field of audio equal loudness compensation processing technology. Attached Figure Description

[0052] The present invention provides a method and system for treating tinnitus and hearing loss with sound frequency and loudness energy compensation, based on the tinnitus frequency F and tinnitus sound pressure level A of the tinnitus and hearing loss patient. t Tinnitus hearing threshold A ht Using parameters such as the loudness curve of tinnitus, and referring to the hearing threshold and pure tone loudness curve of people with normal hearing, the required compensation sound pressure difference D for loudness adjustment in each frequency band is accurately calculated. f This serves as the basis for compensating for the audio energy equal loudness and sound pressure level of therapeutic sounds in each frequency band. The tinnitus therapeutic sound audio equal loudness and energy compensation algorithm provided by this invention ensures that patients with hearing loss experience the same therapeutic sound as those with normal hearing, thus improving the effectiveness and comfort of sound therapy for patients with both tinnitus and hearing loss.

[0053] Example 1

[0054] like Figure 1 As shown, this embodiment provides a method for compensating for the loudness energy of sound frequencies in the treatment of tinnitus and hearing loss, including the following steps:

[0055] 1) Obtain tinnitus parameters and tinnitus hearing threshold A in patients with tinnitus and hearing loss. ht The relative sound pressure level m (in dB) of tinnitus at tinnitus frequency F in patients with tinnitus and hearing loss was calculated.

[0056] 1.1) Obtain tinnitus parameters and tinnitus hearing threshold A in patients with tinnitus and hearing loss. ht Among them, tinnitus parameters include tinnitus frequency F and tinnitus sound pressure level A. t .

[0057] Specifically, the tinnitus frequency F should be the center frequency of the tinnitus. When the tinnitus type in a patient with tinnitus and hearing loss is a pure tone, the tinnitus frequency F is the frequency of the pure tone. When the tinnitus in a patient with tinnitus and hearing loss is narrowband noise, the tinnitus frequency F is the square root of the product of the upper and lower frequency limits of the narrowband noise; the tinnitus sound pressure level A t The intensity of tinnitus in a patient is quantified using sound pressure level as the physical quantity; tinnitus hearing threshold A. htThis is the patient's hearing threshold at the tinnitus frequency F.

[0058] 1.2) Based on the obtained tinnitus parameters and tinnitus hearing threshold A ht Calculate the relative sound pressure level m of tinnitus at tinnitus frequency F in patients with tinnitus and hearing loss:

[0059] Tinnitus hearing threshold A in patients with tinnitus and hearing loss ht Using this as a baseline, the tinnitus sound pressure level A at the tinnitus frequency F is... t With tinnitus hearing threshold A ht The difference was calculated to obtain the tinnitus hearing threshold A in patients with tinnitus and hearing loss. ht The relative sound pressure level of tinnitus is denoted as m dB.

[0060] 2) Measure the pure tone sound pressure level required to maintain the tinnitus sound at the same loudness level in patients with tinnitus and hearing loss, and generate the tinnitus sound equal-loudness curve C1. The sound pressure level at each frequency point on the curve is denoted as A. f .

[0061] Specifically, the tinnitus sound equal-loudness curve refers to the relationship between the sound pressure level and frequency of the equivalent pure tone that keeps the tinnitus sound loudness level constant. The specific process is as follows:

[0062] 2.1) While maintaining the same tinnitus loudness in patients with both tinnitus and hearing loss, measure the equivalent pure tone of the tinnitus sound at N frequency points (f1, f2, f3, f4...f...). N The equal loudness sound pressure level A f .

[0063] Specifically, for example, the N frequency points can be 11 or more of the following: 125Hz, 250Hz, 500Hz, 750Hz, 1000Hz, 2000Hz, 3000Hz, 4000Hz, 6000Hz, 8000Hz, 10000Hz.

[0064] 2.2) Using an interpolation method, M internal frequency points are inserted into each segment of the measured frequency points and equal loudness sound pressure level data, generating a value composed of ((N-1)×(M+1)+1) for each frequency point f and equal loudness sound pressure level A. f The data pairs are mapped to a sequence, which is used to determine the loudness curve C1 of tinnitus.

[0065] 3) Based on universal acoustic standards, determine the normal hearing threshold A at the tinnitus frequency F of a person with normal hearing compared to a patient with tinnitus and hearing loss. nht Specifically:

[0066] 3.1) Determine the equal loudness curves for individuals with normal hearing based on general acoustic standards.

[0067] 3.2) Based on the equal-loudness curves of individuals with normal hearing, determine the normal hearing threshold A of individuals with normal hearing at the tinnitus frequency F of patients with tinnitus and hearing loss. nht .

[0068] Specifically, based on the equal-loudness curve of a person with normal hearing, the sound pressure level at the tinnitus frequency F is calculated as the normal hearing threshold A. nht .

[0069] 4) Based on the relative sound pressure level (m dB) of tinnitus at frequency F in patients with tinnitus and hearing loss, and the normal hearing threshold (A) of normal-hearing individuals at frequency F in patients with tinnitus and hearing loss. nht Determine the pure-tone equal loudness curve C2 for individuals with normal hearing, and denot the sound pressure level at each frequency point on it as A. nf .

[0070] Specifically, based on the same general acoustic standard in step 3) above, determine the loudness level and the pure tone equal loudness curve C2 of a normal hearing person that satisfies the condition of a relative sound pressure level of m dB at the tinnitus frequency F.

[0071] 5) Based on the tinnitus sound equal loudness curve C1, the pure tone equal loudness curve C2 of normal hearing individuals, and the tinnitus hearing threshold A of patients with coexisting tinnitus and hearing loss. ht The normal hearing threshold A at the tinnitus frequency F in patients with tinnitus and hearing loss, compared to individuals with normal hearing. nht The sound pressure difference D to be compensated is calculated. f Specifically:

[0072] 5.1) Based on the tinnitus hearing threshold A of patients with tinnitus and hearing loss. ht The normal hearing threshold A at the tinnitus frequency F in patients with tinnitus and hearing loss, compared to individuals with normal hearing. nht The difference in hearing threshold ldB between patients with tinnitus and hearing loss and those with normal hearing was determined at the tinnitus frequency F.

[0073] Specifically, the tinnitus hearing threshold A of patients with tinnitus and hearing loss is... ht The normal hearing threshold A at the tinnitus frequency F in patients with tinnitus and hearing loss coexisting with normal hearing is compared with that of normal hearing individuals. nht The difference was calculated to obtain the hearing threshold difference ldB between patients with tinnitus and hearing loss and those with normal hearing at the tinnitus frequency F. The hearing threshold difference can be represented in the figure as two hearing threshold baselines with an axial distance of 1 dB, indicating that the hearing threshold of patients with tinnitus and hearing loss is 1 dB higher than that of patients with tinnitus and normal hearing.

[0074] 5.2) Using the pure tone equal loudness curve C2 of a person with normal hearing as a reference template, the part that needs to be reduced to equal loudness in the tinnitus equal loudness curve C1 is determined according to the hearing threshold difference ldB, so as to obtain the shifted tinnitus equal loudness curve C'1.

[0075] Specifically, such as Figure 2As shown, considering that the hearing threshold of patients with tinnitus and hearing loss is 1 dB higher than that of patients with normal hearing and tinnitus, the tinnitus equal loudness curve C1 is schematically shifted downward by 1 dB to obtain the shifted tinnitus equal loudness curve C'1. The sound pressure level A′ at each frequency point on the shifted tinnitus equal loudness curve C'1 is... f for:

[0076] A′ f =A f -l (1)

[0077] 5.3) Compare the shifted tinnitus equal-loudness curve C'1 with the pure-tone equal-loudness curve C2 of a person with normal hearing. The interval between the two curves (e.g.) Figure 2 The black shaded area in the image represents the sound pressure difference D to be compensated during equal loudness adjustment. f :

[0078] D f =A nf -A′ f (2)

[0079] 6) For the tinnitus treatment sound signal, the sound pressure difference D to be compensated. f Based on this, loudness energy compensation processing is performed for audio frequencies.

[0080] Specifically, certain frequency nodes are set, based on the sound pressure difference D to be compensated in each frequency band. f The sound pressure level of the audio signal is precisely reduced to obtain an audio output with equal loudness energy compensation.
