Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] There are many people with hearing loss in the world. They cannot hear or hear clearly various natural sounds within the hearing range of the human ear like normal people. Since hearing loss is difficult to cure, it can only be solved by wearing hearing aids. However, the current low-end hearing aids only amplify the sound, and the hearing aid effect is not ideal; mid-to-high-end hearing aids require specific hearing aid chips, which are expensive and costly.

[0039] In order to solve the problems existing in the prior art, in this embodiment, a hearing aid method, a hearing aid system, an intelligent terminal and a storage medium are proposed to solve the problem that the existing hearing aids only have a simple sound amplification function and the hearing aid effect is not ideal.

[0040] Exemplary Methods

[0041] like Figure 1 As shown, an embodiment of the present invention provides a hearing aid method, which is executed by a smart terminal, and the smart terminal may be a Bluetooth headset. Specifically, the method includes the following steps:

[0042] Step S100, obtaining an analog signal of a target sound;

[0043] In this embodiment, an analog signal of external sound received by a microphone is obtained.

[0044] Step S200, modulating the analog signal to obtain a first digital signal and a second digital signal, wherein spectrum data of the first digital signal is the same as spectrum data of the second digital signal;

[0045] In this embodiment, the analog signal is modulated to obtain the first digital signal and the second digital signal, including: sampling the analog signal according to a preset sampling rate to obtain a sampled signal; quantizing and encoding the sampled signal to obtain the first digital signal, copying the first digital signal, and storing it as the second digital signal. In order to avoid signal distortion when restoring after sampling, the minimum sampling rate for sampling the analog signal is twice the maximum frequency, and the preset sampling rate can be set according to actual conditions and is not limited here.

[0046] Step S300, modifying the first digital signal according to a preset characteristic value to obtain a third digital signal;

[0047] In this embodiment, the modifying the first digital signal according to the preset characteristic value to obtain the third digital signal includes: modifying the first digital signal according to a preset frequency, a preset loudness, and a preset signal-to-noise ratio to obtain the third digital signal.

[0048] In this embodiment, the correcting the first digital signal according to the preset characteristic value includes:

[0049] Acquire sound spectrum characteristics of the first digital signal, where the sound spectrum characteristics include: frequency, loudness, and signal-to-noise ratio;

[0050] The frequency, the loudness and the signal-to-noise ratio are modified according to the preset frequency, the preset loudness and the preset signal-to-noise ratio to obtain a third digital signal.

[0051] In this embodiment, the loudness, frequency and signal-to-noise ratio are compared according to a preset default threshold value to obtain the sound spectrum characteristics of the first digital signal.

[0052] It should be noted that since the frequency range of sound audible to the human ear is 20Hz to 20000Hz, and the frequency range of human voice is approximately 65Hz to 1100Hz, the human voice is more important than other sounds, so the low-frequency interval should be relatively narrow, and the high-frequency interval should be relatively wide. People with hearing loss have different hearing in different sound frequency ranges. Some people have better hearing at low frequencies, some have better hearing at medium frequencies, and some have better hearing at high frequencies. Therefore, when correcting the first digital signal according to the preset characteristic value, the preset characteristic value needs to be adjusted according to the actual situation to meet the needs of people with different hearing losses.

[0053] Step S400, superimposing the second digital signal and the third digital signal to obtain a hearing aid digital signal;

[0054] Step S500: demodulate the hearing aid digital signal to obtain a hearing aid analog signal.

[0055] It should be noted that the third digital signal is a digital signal that is corrected according to preset characteristic values ​​to meet the hearing needs of hearing-impaired people, and the second digital signal is a digital signal of the original target sound. In the process of correcting the first digital signal to obtain the third digital signal, part of the audio signal will be lost, resulting in audio distortion. Therefore, after superimposing the second digital signal and the third digital signal, a sound characteristic that includes both the corrected target sound and the original target sound can be obtained, thereby improving the hearing aid effect.

[0056] In one embodiment, Figure 1As shown, the external sound received by the microphone is obtained, and signal A and signal B are obtained after analog-to-digital conversion. After signal A is corrected, it is superimposed with signal B to output a hearing aid digital signal, and after digital-to-analog conversion, a hearing aid analog signal is output.

[0057] As can be seen from the above, in the scheme of the present invention, by acquiring an analog signal of the target sound; modulating the analog signal to obtain a first digital signal and a second digital signal, wherein the spectrum data of the first digital signal is the same as the spectrum data of the second digital signal; correcting the first digital signal according to a preset characteristic value to obtain a third digital signal; superimposing 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 requires a hearing aid to amplify the sound to help the hearing-impaired, the scheme of the present invention obtains a first digital signal and a second digital signal by modulating the analog signal of the target sound, and corrects the first digital signal according to a preset characteristic value to obtain a third digital signal, superimposes the second digital signal and the corrected third digital signal to obtain a hearing aid digital signal including the original target sound, and demodulates the hearing aid digital signal so that the demodulated hearing aid analog signal contains both the corrected target sound characteristics and the sound characteristics of the original target sound, thereby improving the hearing aid effect.
