Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.
[0020] Embodiment 1, Figure 1 A hearing aid local audiometry method of the present invention is shown. The method can be applied to hearing aids, headphones or other audio playback devices to perform the hearing aid local audiometry method of the present invention to obtain and adjust test data to generate target data that meets pure tone audiometry, thereby realizing local real-time pure tone audiometry. The method specifically includes: 110, obtaining the sampling points of the test frequency, and setting the basic data of each sampling point at each test frequency; in step 110, obtaining the sampling points of the test frequency specifically includes: obtaining the current sampling rate and the current test frequency, and obtaining the current number of cycles according to the current test frequency. The basic data is the audio data played with the sound intensity as the target amplitude, wherein the basic data of each sampling point is set at each test frequency, and the basic data can be preset in the storage of the hearing aid at the factory for pure tone audiometry. In addition, the basic data can also be provided in the hearing aid as a communication interface, through which the hearing aid can communicate with the test server in real time to obtain the basic data of the test server, and download it to the hearing aid or the test terminal connected to the hearing aid.
[0021] 120, generating target data with target sound intensity by pure tone generation algorithm according to basic data and sampling points; in step 120, generating target data by pure tone generation algorithm specifically includes: generating the sound intensity of each sampling point of a sine cycle by a sine function in a trigonometric function. Generating the sound intensity of each sampling point of a sine cycle by a sine function in a trigonometric function specifically includes: determining the peak value and trough value of the sine cycle according to the target amplitude of the basic data; determining the change trend of the sound intensity of the audio data in the basic data with the sine function according to the number and position of the sampling points in a sine cycle, and generating target data with target sound intensity.
[0022] 130, play the hearing aid audio according to the target data. In step 130, when the target data is acquired, the audio data in the target data can be played through the speaker of the hearing aid at the target sound intensity after confirmation by the user, so as to perform pure tone audiometry on the user.
[0023] In this embodiment, the present invention confirms the sampling points of the test frequency points and the basic data at each sampling point; generates target data with target sound intensity through a pure tone generation algorithm according to the basic data and the sampling points; and plays the hearing aid audio according to the target data. The present invention can adjust the sound intensity of the basic data and the basic audio data to the target data with the target sound intensity, thereby enabling the user to perform pure tone audiometry in any quiet environment, without being affected by time and space, and the test is convenient and efficient.
[0024] In step 110, see Figure 2 , the sampling points for obtaining the test frequency points specifically include: 210, obtaining the current sampling rate and the current test frequency, and obtaining the current cycle number according to the current test frequency; 220, by calculating the quotient of the current sampling rate and the current number of cycles, the number of periodic samplings in each sine wave cycle is calculated, and then a sampling point is selected in the sine wave cycle according to the number of periodic samplings.
[0025] In the embodiment shown in steps 210-220, configuration parameters may be preset in the hearing aid to configure the sampling rate and the current test frequency. The hearing aid may also interact with the test server to obtain basic data with the current sampling rate and the current test frequency. In a specific example, the audio file format of the hearing aid basic data and target data adopts PCM format, the sampling rate is 16000Hz, that is, the sampling times in 1s is 16000, the bit number is 16 bits, and the supported audiometric frequencies are 250Hz, 500Hz, 1000Hz, 1500Hz, 2000Hz, 2500Hz, 3000Hz, 3500Hz, 4000Hz, 4500Hz, 5000Hz, 5500Hz, and 6000Hz; among which, the audiometric frequency is 250Hz, which is 250 cycles in 1s; the quotient of the current sampling rate and the current number of cycles is calculated, and the number of periodic samplings in each sine wave cycle is calculated, which is specifically the number of samplings in each sine wave cycle = the number of samplings / the number of cycles, such as at 250Hz, the number of samplings is 16000 / 250=64 times. Other frequencies can refer to 250Hz. In a sine wave cycle, the sampling points can be evenly set according to the number of samplings.
[0026] In step 110, see Figure 3 , the basic data is the audio data played with the sound intensity as the target amplitude. The basic data of each sampling point is set at each test frequency point, including: 310, obtaining the real sound intensity of the pure tone audio file, recorded as X0; 320, at a frequency of n Hz, setting the preset amplitude of the hearing aid to An, and obtaining a test sound intensity Xn; 330, calculate the target amplitude Am through the target amplitude calculation formula: Am= A0 / (10^((Xn- X0) / 20)).
[0027] In steps 310-330, the real sound intensity is obtained by the sum of the standard sound intensity and the reference equivalent threshold sound pressure level, wherein the value of the reference equivalent threshold sound pressure level at different test frequencies is obtained by a preset sound pressure mapping table. In a specific example, the real sound intensity is obtained by the sum of the standard sound intensity and the reference equivalent threshold sound pressure level, namely: dB SPL=dBHL+ RETSPL, wherein dB SPL is the physical unit of sound intensity, the real sound intensity; dB HL is the standard sound intensity, obtained by experiments using healthy hearing people aged 18-25, and the minimum sound pressure level heard by these people at each frequency is set to 0 dBHL; RETSPL is the reference equivalent threshold sound pressure level, measured by experiments using healthy hearing people aged 18-25, and the minimum sound pressure level heard by these people at each frequency is set to 0 dB HL. Taking the in-ear machine as an example, the specific values of RETSPL are as shown in Table 1 below:
[0028] Table 1 The actual sound intensity corresponding to each sound pressure level at each test frequency point of the pure tone audio file is shown in Table 2 below:
[0029] Table 2 In this embodiment 1, Table 1 and Table 2 can be pre-stored in the register of the MCU of the hearing aid, and when the hearing aid local audiometry method is executed, the register of the MCU of the hearing aid is read. In addition, Table 1 and Table 2 can be stored in the test server and obtained through the communication connection between the hearing aid and the test server.
[0030] In addition, when obtaining the target amplitude of the basic data, it is necessary to obtain the test sound intensity. In one example, at a frequency of nHz, the preset amplitude of the hearing aid is set to An, and the test sound intensity Xn is obtained. Among them, the preset amplitude can be measured according to historical data or set according to preset data. After obtaining the test sound intensity and the actual sound intensity, the target amplitude Am is calculated by the target amplitude calculation formula: Am= A0 / (10^((Xn- X0) / 20)). The target amplitude Am can be pre-stored in the register of the MCU of the hearing aid, and when the local audiometry method of the hearing aid is executed, it is obtained by reading the register of the MCU of the hearing aid. In addition, the target amplitude Am can be stored in the test server and obtained through the communication connection between the hearing aid and the test server. In one example, when performing local audiometry of the hearing aid, the target amplitude Am of the basic data can be directly called to calculate the target sound intensity.
[0031] In step 120, see Figure 4, generating target data through a pure tone generation algorithm, specifically including: generating the sound intensity of each sampling point of a sine cycle through a sine function in a trigonometric function. Wherein, the sine function is y=Asin(ωt+φ); in the present invention, the sound intensity of the audio data at each point of the sine function can be determined by the target amplitude. Specifically including: 410, determining the peak value and the trough value of the sine cycle according to the target amplitude of the basic data; 420 , determining a trend of a sound intensity of the audio data in the basic data changing with a sine function according to the number and position of the sampling points in a sine cycle, and generating target data with a target sound intensity.
[0032] In steps 410-420, the target amplitude of the basic data is the peak value of the sine cycle, and the opposite of the target amplitude of the basic data is the trough value of the sine cycle; according to the number and position of the sampling points, the specific position of the sampling point in the sine cycle is determined, and then the size of the sound intensity is determined according to the position difference between the specific position and the peak value and trough value of the sine cycle, so that the target sound intensity changes like the trend of the sine function. The basic audio data is adjusted to the target data with the target sound intensity, so that the user can perform pure tone audiometry in any quiet environment, which is not affected by time and space, and the test is convenient and efficient.
