Detailed ways

The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not used to limit the present invention.

The acoustic unit described in the embodiment of the present invention may be a device that converts audio data into sound, such as a headset, a speaker, or a speaker.

After research, the inventor found that the reason for improving the sound reproduction of the acoustic unit cannot effectively improve the experience of all users, and cannot meet the needs of all users for auditory effects. The reason is that each user has different perception characteristics of sound. Specifically, the range of human perception of sound is generally between 10HZ-22HZ. In this frequency range, the specific structure of the human cochlea can decompose the received sound into resonances in various frequency bands. These resonances The intensity is transmitted to the brain through the cilia of the nerve endings, so that humans can hear (perceive) sounds in various frequency bands; due to factors such as age, environmental noise, disease or accidents, certain human auditory nerve endings will be caused to varying degrees The wear and tear often makes each user's perception of different frequencies of sound different to different degrees; for example, under the same sound intensity, older users tend to be sensitive to the sound of certain frequency bands in high-frequency sound Low, when the sound intensity of these frequency bands is low, the user will not hear clearly; that is to say, when the music they listen to includes both low-frequency content and high-frequency sound content, the user will often be unable to Listening to low frequency content clearly perceives high frequency content in music.

Based on the above recognition, in order to improve the user's hearing experience, an embodiment of the present invention provides an audio processing method for an acoustic unit, as shown in FIG. 1, including:

S11. Acquire the user's hearing curve, which is used to characterize the user's hearing sensitivity to sounds of different frequencies within the preset audio frequency range;

Under normal circumstances, the user's hearing wear level needs to be tested and quantified with a single-frequency sound through a standard program (that is, quantized into a certain volume value in decibels). The decibel value of hearing sensitivity in each frequency band of each ear of each person is different. According to the hearing test results, the hearing curve corresponding to the user can be obtained (the hearing curve can be divided into left ear and right ear). The specific method can be As shown in Figure 2, in Figure 2, the ordinate is the decibel value, and the abscissa is the frequency value. The dot (sensing point) in the figure is the decibel value of the lowest sound that a user can perceive at the corresponding frequency point. (The decibel value can characterize the hearing sensitivity of a certain ear of the user at a corresponding frequency point). By connecting each sensing point corresponding to each ear, a corresponding hearing curve can be established for each ear of the user.

It should be noted that the interval between the frequency points used as the perception points when acquiring the user's hearing curve can be set by those skilled in the art based on experience, and is not specifically limited here.

In addition, the method for acquiring the hearing curve in the embodiment of the present invention may also be other methods in the prior art, and is not limited to the method disclosed above in the embodiment.

S12. According to the preset sound intensity correction algorithm, generate the sound intensity correction rule corresponding to the user with the hearing curve as a parameter;

The sound intensity correction algorithm in the embodiment of the present invention may preset a standard hearing curve, and then set the sound intensity correction value of the user at each preset frequency point according to the difference between the user’s hearing curve and the standard hearing curve. Generate rules.

In practical applications, it can be based on the difference between the user’s hearing curve and the standard hearing curve, using a preset empirical formula to convert the required sound intensity correction value for each frequency point; at this time, preferably, the user can also be generated The corresponding sound intensity correction curve can determine the required sound intensity correction for different frequencies.

For the sound content in different sound frequency bands, the degree of sound intensity correction required by the user from the inability to hear the sound to achieve a comfortable voice is also different. Using a uniform compensation coefficient or compensation method in each frequency band may cause some The sound intensity compensation amplitude of some frequency bands is too large, or the sound intensity correction amplitude of some frequency bands is insufficient; in order to be able to generate sound intensity correction values for users more accurately, and avoid excessive or insufficient correction, further, embodiments of the present invention The preset empirical formula can also include multiple, so that according to the difference between the user’s hearing curve and the standard hearing curve, different sound frequency bands use different empirical formulas to calculate the sound corresponding to each different sound frequency band. Strong correction value.

The frequency band where the difference between the user's hearing curve and the standard hearing curve exceeds the preset threshold is determined as the frequency band to be corrected; then, according to the empirical formula, a corresponding sound intensity correction value can be set for each frequency band to be corrected for the user.

It should be noted that the sound intensity correction value in the embodiment of the present invention can be either a positive value or a negative value, that is, it can either enhance the sound intensity of audio data in a certain frequency band, or weaken audio in a certain frequency band. The sound intensity of the data and the method for determining the specific sound intensity correction value can be obtained by those skilled in the art according to actual needs or a limited number of experiments, which is not specifically limited here.

S13. According to the sound intensity correction rule, generate the sound intensity correction value of the currently acquired audio data in real time;

For example, suppose that according to the hearing curve of user A, it is known that in the 80HZ-90HZ sound frequency range, the best sound intensity discrimination value is 35 decibels. Below this decibel value, the sound content cannot be accurately discerned; At the time, the sound intensity correction rule can include: in the 80HZ-90HZ interval, when the sound intensity value of the audio data is less than 35 decibels, according to the empirical formula, the sound intensity value of the audio data is enhanced to 35 decibels or one of 35 decibels or more. The expected sound intensity value suitable for user A's hearing; preferably, the range of the sound intensity value output by the acoustic unit can be controlled (mapped) within 35 to 120 decibels.

When user A listens to audio content (such as music or radio) through acoustic units such as earphones, speakers, etc., the original audio data of the audio content needs to be preprocessed based on the above sound intensity correction rules; specifically, the original The current frequency value and sound intensity value of the audio data, and the corresponding sound intensity correction value is generated in real time. For example, when the frequency value of a certain time point (or time period) in the original audio data is 85HZ and the sound intensity is 30 decibels, it is necessary to calculate in real time to enhance the sound intensity value of the currently acquired original audio data to the expected sound intensity value The required sound intensity correction value.

S14. Correct the audio data in real time according to the sound intensity correction value;

Through the real-time generated sound intensity correction value, the degree of sound intensity correction required for corresponding correction of the current audio data can be determined, so that the sound intensity of the corrected audio data can meet the hearing needs of the user.

After the above sound intensity correction rule is generated for user A, through the embodiment of the present invention, all the parts of the audio data whose frequency value is 85HZ and the sound intensity is lower than 30 decibels can be corrected in real time, so that the corrected The audio data can be adapted to user A's hearing needs.

S15. Send the corrected audio data to the sound module of the acoustic unit.

The sound module of the acoustic unit such as earphones or speakers generally uses audio data as electrical signals, and generates sound waves by converting the electrical signals into mechanical vibrations, thereby realizing the playback of sound content. Because the original audio can be played by the embodiment of the present invention. The data is corrected, so the user can hear the sound content played by the earphone or speaker more clearly by increasing the sound intensity in the frequency range where the user’s hearing is impaired, thereby avoiding the user’s personal hearing problems caused by Loss of reception of certain sound content.

In practical applications, each step in the embodiment of the present invention may be implemented by multiple devices operating in cooperation, or may be implemented by one device.
