At present, a plurality of hearing loss people are available in the world, and the hearing loss people cannot hear or hear various sounds falling within the hearing range of human ears like normal people, and the hearing loss is difficult to cure and can only be solved by wearing a hearing aid, however, the existing low-end hearing aid only expands the sounds, and the hearing aid effect is not ideal; the middle-high-end hearing aid needs a special hearing aid chip, and the hearing aid chip is expensive in manufacturing cost and high in cost.
In order to solve the problems in the prior art, in the present embodiment, a hearing aid method, a hearing aid system, a smart terminal, and a storage medium are provided to solve the problem that the hearing aid in the related art has only a simple sound amplification function and is not ideal in hearing aid effect.
Exemplary method
As shown in fig. 1, an embodiment of the present invention provides a hearing aid method, where the method is performed by an intelligent terminal, and the intelligent terminal may be a bluetooth headset, and specifically, the method includes the following steps:
step S100, acquiring an analog signal of a target sound;
in this embodiment, an analog signal of the external sound received by the microphone is obtained.
Step S200, modulating the analog signal to obtain a first digital signal and a second digital signal, wherein the frequency spectrum data of the first digital signal is the same as the frequency spectrum data of the second digital signal;
in this embodiment, the modulating the analog signal to obtain the first digital signal and the second digital signal includes: sampling the analog signal according to a preset sampling rate to obtain a sampling signal; and quantizing and coding the sampling signal to obtain the first digital signal, copying the first digital signal, and storing the first digital signal as the second digital signal. In order to avoid signal distortion when recovering after sampling, the lowest sampling rate of sampling the analog signal is 2 times of the highest frequency, and the preset sampling rate may be set according to an actual situation, which is not limited herein.
Step S300, correcting the first digital signal according to a preset characteristic value to obtain a third digital signal;
in this embodiment, the modifying the first digital signal according to the preset feature value to obtain a third digital signal includes: and modifying the first digital signal according to the preset frequency, the preset loudness and the preset signal-to-noise ratio to obtain a third digital signal.
In this embodiment, the modifying the first digital signal according to the preset feature value includes:
acquiring sound spectral characteristics of the first digital signal, the sound spectral characteristics including: frequency, loudness, and signal-to-noise ratio;
and modifying the frequency, the loudness and the signal-to-noise ratio according to a preset frequency, a preset loudness and a preset signal-to-noise ratio to obtain a third digital signal.
In this embodiment, the loudness, the frequency, and the signal-to-noise ratio are compared according to a preset default threshold value, so as to obtain the sound spectrum characteristic of the first digital signal.
It should be noted that, since the frequency range of sound audible to human ears is 20Hz to 20000Hz, and the frequency range of human voice is about 65Hz to 1100Hz, human voice is more important than other sounds, the low frequency interval is relatively narrow, and the high frequency interval is relatively wide. Hearing impaired people have different audios in different sound frequency ranges, some people have better audios at low frequencies, some people have better audios at medium frequencies, and some people have better audios at high frequencies. Therefore, when the first digital signal is corrected according to the preset characteristic value, the preset characteristic value needs to be adjusted according to the actual situation so as to meet the requirements of different hearing loss people.
Step S400, superposing the second digital signal and the third digital signal to obtain a hearing aid digital signal;
and step S500, demodulating the hearing aid digital signal to obtain a hearing aid analog signal.
It should be noted that the third digital signal is a digital signal that is modified according to a preset feature value and satisfies the hearing requirement of the hearing impaired person, and the second digital signal is a digital signal of the original target sound, and since a part of the audio signal may be lost in the process of modifying the first digital signal to obtain the third digital signal, which causes audio distortion, after the second digital signal and the third digital signal are superimposed, the sound characteristic that both the modified target sound and the original target sound are included can be obtained, and the hearing aid effect is improved.
In one embodiment, as shown in fig. 1, external sound received by a microphone is acquired, and is subjected to analog-to-digital conversion to obtain a signal a and a signal B, the signal a is subjected to correction processing, and is subjected to superposition processing with the signal B to output a hearing aid digital signal, and is subjected to digital-to-analog conversion to output a hearing aid analog signal.
Therefore, in the scheme of the invention, the analog signal of the target sound is obtained; modulating the analog signal to obtain a first digital signal and a second digital signal, wherein the frequency spectrum data of the first digital signal is the same as the frequency spectrum data of the second digital signal; correcting the first digital signal according to a preset characteristic value to obtain a third digital signal; superposing the second digital signal and the third digital signal to obtain a hearing aid digital signal; and demodulating the hearing aid digital signal to obtain a hearing aid analog signal. Compared with the prior art that hearing loss persons need to be helped by expanding sound through a hearing aid, the scheme of the invention modulates the analog signal of the target sound to obtain the first digital signal and the second digital signal, corrects the first digital signal according to the preset characteristic value to obtain the third digital signal, superposes the second digital signal and the corrected third digital signal to obtain the hearing aid digital signal comprising the original target sound, and demodulates the hearing aid digital signal, so that the demodulated hearing aid analog signal not only comprises the corrected target sound characteristic, but also comprises the sound characteristic of the original target sound, and the hearing aid effect is improved.
