Abstract

The invention provides a method and equipment for suppressing external howling of a hearing aid. The method includes: obtaining the first framed audio by framing the received first audio, judging the first framed audio frame by frame to determine the content of the received first audio, and similarly obtaining the second audio Content, if the content of the first audio is the same as that of the second audio, then determine that the second audio is the external howling of the hearing aid, and synthesize the first amplified audio and the second amplified audio to complete the suppression of the external howling of the hearing aid. The present invention can effectively suppress the external howling of the hearing aid, and improve the user experience of hearing-impaired patients in obtaining external sound by using the hearing aid.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of hearing aid filtering, and in particular, to a method and device for suppressing external howling of a hearing aid. Background technique [0002] Wearing a hearing aid is the best solution for hearing impaired patients to restore their hearing. In the process of using hearing aids, due to the high integration and small size of digital hearing aids, the signal output from the speaker is easily leaked out from the gap between the earplug and the ear canal or the vent hole of the hearing aid. The leaked sound signal is picked up again by the microphone and output again from the speaker, forming a closed feedback loop. When the gain of the whole system is too large and a certain phase condition is met, it will cause the instability of the system, which will eventually cause the hearing aid to generate external howling, which in turn affects the hearing aid patients' experience of using ...
