The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
The acoustic unit described in the embodiment of the present invention may be an earphone, a speaker, or a device that converts audio data into sound, such as a sound box.
The inventor finds that the improvement of the sound restoration degree of the acoustic unit cannot effectively improve the use experience of all users and cannot meet the requirement of all users on the auditory effect, because the perception characteristics of each user on sound are different; in particular, the human perception of sound is generally in the range of 10HZ to 22HZ, and in this frequency interval, the specific structure of the human cochlea can decompose the received sound into resonances in various frequency bands, and the intensity of the resonances is transmitted to the brain through the cilia of nerve endings, so that the human can hear (perceive) the sound in various frequency bands; due to the fact that factors such as age, environmental noise, diseases or accidents cause abrasion of certain specific auditory nerve endings of human beings to different degrees, perception abilities of each user to sounds with different frequencies are differentiated in different degrees; for example, under the same sound intensity, an elderly user often has low sensitivity to sounds in some frequency bands of high-frequency sounds, and when the sound intensity of the frequency bands is low, the user may not hear clearly; that is, when the music listened to by the user includes both low-frequency content and high-frequency sound content, the user may not be able to clearly perceive the high-frequency content in the music as listening to the low-frequency content.
Based on the above recognition, in order to improve the hearing experience of the user, an embodiment of the present invention provides an audio processing method for an acoustic unit, as shown in fig. 1, including:
s11, acquiring a hearing curve of the user, wherein the hearing curve is used for representing the hearing sensitivity of the user to sounds with different frequencies in a preset audio frequency range;
typically, the user's hearing wear level needs to be tested and quantified (i.e., quantified to a certain volume value in decibels) by a single frequency sound through standard procedures. The hearing sensitivity decibel values of each frequency band of each ear of each person are different, a hearing curve corresponding to a user can be obtained according to a hearing test result (the hearing curve can be divided into a left ear and a right ear), the specific mode can be as shown in fig. 2, the ordinate is a decibel value, the abscissa is a frequency value, and a dot (sensing point) in the graph is a decibel value of the lowest sound which can be sensed by a user at a corresponding frequency point (the decibel value can represent the hearing sensitivity of the user at the corresponding frequency point), and the hearing curve corresponding to each ear of the user can be established by connecting each sensing point corresponding to each ear.
It should be noted that the interval between the frequency points as the sensing points when the hearing curve of the user is obtained may be set by a person skilled in the art based on experience, and is not limited specifically herein.
In addition, the hearing curve acquisition method in the embodiment of the present invention may be other methods in the prior art, and is not limited to the method disclosed in the embodiment.
S12, generating a sound intensity correction rule corresponding to the user by taking the hearing curve as a parameter according to a preset sound intensity correction algorithm;
the sound intensity correction algorithm in the embodiment of the invention may be to preset a standard hearing curve, and then set a generation rule of the sound intensity correction value of the user at each preset frequency point according to the difference value between the hearing curve of the user and the standard hearing curve.
In practical application, the sound intensity correction value required by each frequency point can be converted by a preset empirical formula according to the difference value between the user hearing curve and the standard hearing curve; in this case, it is preferable to generate a sound intensity correction curve corresponding to the user, so that sound intensity corrections required for different frequencies can be determined.
For sound contents in different sound frequency band ranges, sound intensity correction degrees required by a user for comfortably distinguishing sound from sound which cannot be heard clearly are different, and the sound intensity compensation amplitude of some frequency bands is possibly too large or the sound intensity correction amplitude of some frequency bands is insufficient by using a uniform compensation coefficient or a compensation mode in each frequency band; in order to generate the sound intensity correction value for the user more accurately and avoid over-correction or under-correction, further, the preset empirical formula in the embodiment of the present invention may further include a plurality of empirical formulas, so that different sound frequency segments adopt different empirical formulas to calculate the sound intensity correction value corresponding to each different sound frequency segment according to the difference between the user hearing curve and the standard hearing curve.
Determining a frequency band of which the difference value between the user hearing curve and the standard hearing curve exceeds a preset threshold value as a frequency band to be corrected; then, according to an empirical formula, a corresponding sound intensity correction value can be set for each frequency band of the user to be corrected.
It should be noted that the sound intensity correction value in the embodiment of the present invention may be a positive value or a negative value, that is, the sound intensity of the audio data in a certain frequency band may be enhanced, or the sound intensity of the audio data in a certain frequency band may be weakened, and a specific determination method of the sound intensity correction value may be obtained by a person skilled in the art according to actual needs or a limited number of experiments, which is not limited specifically herein.
S13, generating a sound intensity correction value of the currently acquired audio data in real time according to the sound intensity correction rule;
for example, suppose that the optimal sound intensity resolution value is 35 db in the 80HZ-90HZ sound frequency range according to the hearing curve of the user a, and the sound content cannot be accurately resolved below the optimal sound intensity resolution value; in this case, the sound intensity correction rule may include: in the interval of 80HZ-90HZ, when the sound intensity value of the audio data is less than 35 dB, the sound intensity value of the audio data is enhanced to 35 dB or a sound intensity expected value suitable for the hearing of a user A according to an empirical formula; preferably, the range of the change of the sound intensity value output by the acoustic unit can be controlled (mapped) to be within 35-120 decibels.
When a user a listens to audio content (such as music or broadcast) through an acoustic unit such as an earphone or a stereo, the original audio data of the audio content needs to be preprocessed based on the sound intensity correction rule; specifically, the current frequency value and the sound intensity value of the original audio data are determined in real time, and the corresponding sound intensity correction value is generated in real time. For example, when the frequency value at a certain time point (or time period) in the original audio data is 85HZ and the sound intensity is 30 db, a sound intensity correction value for enhancing the sound intensity value of the currently acquired original audio data to the expected sound intensity value needs to be calculated in real time.
S14, correcting the audio data in real time according to the sound intensity correction value;
the sound intensity correction value generated in real time can determine the sound intensity correction degree required when the current audio data is correspondingly corrected, so that the sound intensity of the corrected audio data can meet the auditory requirement of a user.
After the sound intensity correction rule is generated for the user a, by the embodiment of the present invention, all the portions of the audio data having the frequency value of 85HZ and the sound intensity lower than 30 db can be corrected in real time, so that the corrected audio data can adapt to the hearing requirement of the user a.
And S15, transmitting the corrected audio data to a sound production module of the acoustic unit.
The sound production module of the acoustic unit such as the earphone or the sound box generally takes audio data as an electric signal, and generates sound waves by converting the electric signal into mechanical vibration, so that the sound content is played.
In practical applications, each step in the embodiment of the present invention may be implemented by cooperating multiple devices, or may be implemented by using one device.
In a manner that the embodiment of the present invention is implemented by cooperating a plurality of devices, the two steps of obtaining the hearing curve and generating the sound intensity reinforcement rule corresponding to the user in step S11 and step S12 may be implemented by a single device, or implemented by two devices, respectively, where the device may be a mobile terminal such as a mobile phone or a PAD, or may be a computer, or may be a dedicated hearing curve testing device. Steps S13 to S15 in the embodiment of the present invention may be implemented in another apparatus, that is, the steps of implementing audio processing in steps S13 to S15 are implemented as one audio processing device for an acoustic unit; the audio processing device can exist independently, and can also be used as an accessory part of an earphone or a sound box; when the audio processing device exists independently, the audio processing device can be adapted to the sound source equipment to acquire original audio data on one hand, and adapted to the earphone or the sound box to provide modified audio data on the other hand.
In summary, in the embodiment of the present invention, the hearing curve of the user is first obtained, so that the difference of the perception abilities of the user on different frequencies of sound can be known; then, through generating personalized sound intensity correction rules for the user, the original audio data can be corrected in a sound frequency area with lower hearing sensitivity of the user in a sound intensity enhancing mode, so that the user can obtain consistent hearing effects on all sound frequencies in the audio listened by the user, the phenomenon that sound content is lost in a frequency part with weak hearing is avoided, and the hearing experience of the user is effectively improved.
