Abstract

The invention provides a hearing aid comprising a left ear aid, a right ear aid, and a portable terminal. The left ear aid comprises a left microphone, a left receiver, a first wireless transceiver, and a first battery. The right ear aid comprises a right microphone, a right receiver, a second transceiver and a second battery. The portable terminal comprises a third wireless transceiver, a dual-channel digital signal processor and a third battery. The third wireless transceiver receives left and right channel output. Acoustical signals processed by the dual-channel digital signal processor are output from left and right channels by the third transceiver. The digital signal processing part of the hearing aid is moved from the ear aids to the portable terminal, so that load of the batteries of the ear aids is reduced; a high-performance hardware circuit of the portable terminal, a flexible algorithm and more sufficient battery level provide wide functional extension and update space for complex digital signal processing, especially for binaural voice signal processing.

Description

technical field [0001] The present invention relates to the field of hearing aid devices, in particular to a binaural hearing aid device based on a portable terminal. Background technique [0002] With the rapid development of China's aging population and the improvement of people's living standards, hearing aids, electronic devices that solve the common sensorineural and mixed hearing loss of the elderly, will be more accepted by hearing loss patients. . Hearing aids amplify the sound entering the ear while performing speech enhancement processing such as noise suppression, so that hearing-impaired patients can correctly recognize sounds at a volume acceptable to normal-hearing people. [0003] Three trends emerge in the development of contemporary and future hearing aids. One is because of aesthetic reasons, the volume of hearing aids is constantly miniaturized, especially in-ear or ear canal customized hearing aids, which can be inserted into the ear canal like earplugs...
