Hearing aid effect evaluation testing device

Abstract

The invention belongs to the field of hearing aids and discloses a hearing aid effect evaluation testing device. The device comprises a device body, and a sound generation module and a signal input and output module are arranged in the device body; the device body is provided with a working switch and a sound emitting device, and the working switch and the sound emitting device are both connectedwith the sound generating module; the signal input and output module comprises an input interface and an output interface, and the input interface is connected with the audiometer; and the output interface is connected with the processing module. According to the invention, a fitting tester can directly detect a threshold value of a specific frequency after a hearing impaired person wears the hearing aid, so that the hearing aid adjustment test is more accurate, and the hearing impaired person can more comfortably wear the hearing aid.

Description

technical field [0001] The invention relates to the technical field of hearing aids, in particular to a hearing aid effect evaluation testing device. Background technique [0002] Sound is produced by the vibration of objects. The object that is making sound is called the sound source. The sound source vibrates the small bones of the inner ear (auditory ossicles). These vibrations are converted into tiny electronic brain waves, which are the sounds we perceive. The inner ear works on the same principle that a microphone captures sound waves or a speaker pronounces, it's the relationship between moving mechanical parts and air pressure waves. [0003] A hearing aid is a small loudspeaker that amplifies the originally inaudible sound, and then uses the residual hearing of the hearing-impaired to send the sound to the auditory center of the brain so that the sound can be felt. Hearing aids are generally composed of five parts: microphone, amplifier, earphone, power supply and ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the problem in the prior art that the fitter adjusts the specific frequency through repeated communication with the hearing-impaired person according to experience, there is a problem that the fitting effect is poor; the present invention provides a method that allows the fitter to directly detect the hearing-impaired person The threshold of a specific frequency after wearing a hearing aid, so that the hearing aid can be adjusted and matched more accurately, so that the hearing-impaired can hear more clearly and comfortably when wearing a hearing aid.
