Problems solved by technology

When the sum of the external acoustic feedback and the internal gain of the hearing aid makes the closed-loop gain from the hearing aid microphone to the loudspeaker greater than 1, it will cause the hearing aid to howl and degrade the audio quality
Excessive howling can even cause further hearing loss for hearing-impaired users. Therefore, the problem of how to improve the hearing effect needs to be solved urgently

Abstract

The embodiment of the invention discloses a signal processing method and a related product, which are applied to electronic equipment, the electronic equipment comprises a microphone array composed of M microphones and a single microphone, M is a positive integer, and the method comprises the following steps: collecting voice signals through the microphone array to obtain M first sound signals, fusing the M first sound signals to obtain a fused signal; performing subtraction operation on the fusion signal and an output signal of a self-adaptive filter to obtain a residual signal, the self-adaptive filter being used for simulating an external sound feedback path; inputting the residual signal, a second sound signal acquired by the single microphone and the fusion signal into a frequency domain processing module for processing to obtain an intermediate signal; and inputting the intermediate signal into a hearing aid algorithm module for processing to obtain a target signal. By adopting the embodiment of the invention, the hearing effect can be improved.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a signal processing method and related products. Background technique [0002] With the popularization and application of electronic devices (such as mobile phones, tablet computers, etc.), electronic devices can support more and more applications, and their functions are becoming more and more powerful. Indispensable electronic supplies. [0003] Under normal circumstances, the outer auricle of the human ear can resonate and reflect external sound waves through its physical shape, so as to enhance the sound of specific frequency bands (such as speech) and assist sound source localization. The focal position of its resonance and reflection is at the concha cavity of the opening of the external auditory canal. Therefore, for hearing aids such as hearing aids, hearing aids, bone conduction earphones and cochlear implants, the best position for collecting ex...
