Mobile phone APP for assisting hearing impaired people in hearing aid

Abstract

The invention discloses a mobile phone APP for assisting hearing impaired people in hearing aid, relates to the technical field of collection hearing aid, and aims to solve the problem that the existing voice signal is neither linear nor steady-state, so that a hearing aid based on Fourier transformation has great defects when processing a speech sound signal. Due to insufficient representation of a time fine structure related to consonants, hearing aids in the market generally have the problem that the clarity is reduced after sound amplification. The mobile phone hearing aid function comprises beam forming (sound source positioning), AI automatic noise reduction, echo suppression, global compression, automatic gain control and an EMD algorithm; the falling alarm system measures the motion acceleration and angle information judgment in the three-axis direction through an acceleration sensor and a gyroscope in the mobile phone; when the hearing aid function of the mobile phone is turned on, sound is continuously collected through an earphone or a microphone of the mobile phone and converted into audio.

Description

technical field [0001] The invention relates to the technical field of mobile phone hearing aids, in particular to a mobile phone APP for assisting hearing-impaired persons in hearing aids. Background technique [0002] The mobile phone hearing aid system allows hearing-impaired people to communicate with others in daily life without barriers and easily with the help of smartphones without wearing expensive hearing aids. According to statistics, my country has the largest number of hearing-impaired people It is one of the countries in China with a total population of more than 200 million people, so how to improve hearing and lead a normal life for such a large group of people has become a difficult problem that we need to gradually overcome. [0003] At present, regardless of the high, medium and low-end hearing aids on the market, their algorithm design is based on Fourier frequency, and the audiogram used is still pure sinusoidal sound based on Fourier frequency, but the e...

Problems solved by technology

[0004] The purpose of the present invention is to provide a mobile phone APP for assisting hearing-impaired persons to perform hearing aids, so as to solve the problem that the existing speech signal is neither linear nor steady-state in the above-mentioned background technology, so the Fourier transform-based Hearing aids have major defects in processing speech signals. Due to the insufficient representation of the time fine structure related to consonants, the hearing aids on the market generally suffer from the phenomenon of reduced clarity after amplifying the sound.
