Abstract

The invention discloses a hearing test device, comprising a headset and a stimulating sound source; the headset is used for receiving stimulating sound wave emitted by the stimulating sound source. The hearing test device also comprises a data processor and an evaluation module connected with the data processor; a speaker and an otoacoustic sensor embedded in the headset, the speaker is connected with the stimulating sound source, the otoacoustic sensor is used for picking an otoacoustic signal generated in the cochlea of a subject and transmitting the otoacoustic signal to the data processor for signal processing, and the evaluating module evaluates hearing condition of the subject and sends out hearing test results. The hearing test device can provide hearing test for the subject when the subject enjoys music or converses; the otoacoustic sensor in the headset may receive the otoacoustic emission signal from the cochlea; the data processor and the evaluation module evaluate hearing of the subject; evaluation is not limited by ambient and stimulating sound source frequency; hearing hest can be performed anytime and anywhere.

Description

technical field [0001] The invention relates to the technical field of hearing test, in particular to a hearing test device. Background technique [0002] The hearing test mainly checks the degree of hearing loss of a person, which is a subjective value, that is, the number of decibels at which you can hear the smallest sound at different frequencies; the value of air conduction and bone conduction can also be used to judge the nature of your deafness, whether it is neurological or Whether it is conductive or mixed, etc., the auditory function status and auditory system of the subject can be understood through the subject's response to the acoustic stimulus. At present, the hearing screening of infants and young children adopts the method of otoacoustic emission. Otoacoustic emission is a kind of audio energy that is produced in the cochlea and released into the external auditory canal through the ossicle chain and tympanic membrane. Otoacoustic emission refers to the audio ...
