therefore, the high-definition microphone pickup can be obtained by matching the double-microphone acquisition with the action of the differential amplification circuit, so that high-definition conversation is realized.

With regard to the implementation of the hearing aid function, the hearing status is determined via a data processing & switching module (APP) before starting and entering the function, and then the system configures an individualized compensation scheme according to the hearing status. In the specific working process, a group of noise reduction microphones arranged at the lower parts of two glasses legs pick up human voice and environmental sound, and signals are output to an audio unit (SPK) and synchronously played back to a user through noise reduction processing and an amplifying circuit (a volume compensation scheme combines the hearing test condition of the user and the internal setting of a DSP to carry out volume + or holding), so that the weak listening person is assisted to acquire complete sound source information.

The specific working principle is as follows: when a person is in face-to-face conversation, the called party acquires two sound signals, namely a voice signal Vvoice1 of the other party and an environmental noise Vnoise 1; meanwhile, the noise reduction microphone generates two electric signals, one is a voice signal Vvoice2 of the other party and the other is an environmental noise Vnoise2, the inside of the system (chip noise reduction module) recognizes and generates a signal Vnoise3 with a waveform opposite to that of Vnoise2 to cancel the noise Vnoise2, and the voice signal Vvoice1 is enhanced or maintained through an amplifying circuit and synchronously output to the SPK for playback to the receiver party (i.e. the useless noise signal Vnoise2 is eliminated, and the voice signal Vvoice2 is maintained or amplified), at this time:

vvoice1+ Vnosie1+ Vvoice2+ Vnosie2-Vnosie3> V acoustic signals;

through the microphone collection of making an uproar, the system falls the effect of making an uproar and handles the partial noise of elimination cooperation amplifier circuit, promotes effective speech signal, just can acquire the high definition and remain the sound signal that has the weakening ambient noise to realize assisting and listen the function.

The means for enhancing the voice signal and weakening the environmental noise signal is the prior art, and other modes in the prior art can be adopted for operation and processing according to actual needs.
