Autonomous fitting hearing aid system based on intelligent terminal and method thereof

Abstract

The invention discloses an autonomous fitting hearing aid system based on an intelligent terminal. The system comprises an ear hearing aid used for realizing hearing compensation and a mobile intelligent terminal used for realizing audiometry and fitting. The ear hearing aid and the mobile intelligent terminal carry out wireless communication. In a fitting method, through a questionnaire and audiometry of left and right ears respectively, a hearing condition of a user is acquired. Based on the hearing condition, a hearing map and hearing damage state data are made; hearing compensation prescriptions of left and right ears of the user are generated so as to acquire different voice frequencies of the left and right ears of the user and different sound strength gains, parameters are arranged on hardware of the ear hearing aid, and then a voice signal received by a microphone is segmented according to a frequency, and different amplification and compression are adopted for voices with different frequency ranges. A noise suppression algorithm is used to restrain noises generated by an environment and a hearing aid circuit. Signals of each frequency range are synthesized and finally the synthesized voice signal is output through a loudspeaker. By using the system and the method, fitting cost of the hearing aid user can be greatly reduced.

Description

technical field [0001] The invention belongs to the field of hearing aid design, and relates to an autonomous fitting hearing aid which integrates audiometry, fitting and hearing compensation through the interconnection between a smart phone and an ear-side hearing aid. Background technique [0002] China's population aging is accelerating. In 2014, the elderly accounted for 15% of the total population in China. By 2030, it will be close to 30%. China will become the country with the highest aging rate in the world. The party and the state attach great importance to the aging of the population. The State Council issued the "Guiding Opinions on Promoting the Integration of Medical and Health Care and Elderly Care Services" in November 2015, which required "to promote the extension of medical and health services to communities and families, and to promote community and home-based care services." , to provide continuous health management services and medical services for the el...
