Abstract

The invention provides a hearing threshold and/or hearing state detection system and method. The detection system comprises a collection and transmission system for transmitting a stimulation signal and collecting an ear canal signal and a hearing threshold analysis and prediction system including a hearing threshold detection module, a conventional test module and/or a hearing state screening module. The hearing threshold detection module determines hearing thresholds corresponding to different stimulation frequencies through a pre-trained network model; the conventional test module adaptively selects a test intensity range through the collection and transmission system and predicts a hearing threshold corresponding to the stimulation frequency point through a pre-trained network model; and the screening module is used for screening the hearing state through the pre-trained network model by the collection and transmission system. The detection result is accurate and the hearing threshold and/or hearing state detection system and method can be suitable for different demand scenes.

Description

technical field [0001] The invention relates to a hearing threshold and / or hearing state detection system and method based on the I / O function of SFOAEs, and relates to the technical field of hearing system detection. Background technique [0002] Otoacoustic emissions (OAEs) are weak audio energy produced in the cochlea of ​​the inner ear, transmitted through the ossicular chain and tympanic membrane, and released to the external auditory canal. It is part of the normal function of the human ear. According to the presence or absence of external stimuli, otoacoustic emissions can be divided into two categories: spontaneous otoacoustic emissions (SOAEs) and evoked otoacoustic emissions (EOAEs). EOAEs are divided into Transient-Evoked Otoacoustic Emissions (TEOAEs), Distortion-Product Otoacoustic Emissions (DPOAEs) and Stimulus-frequency Otoacoustic Emissions (Stimulus- Frequency Otoacoustic Emissions, SFOAEs) three categories. [0003] Since the pure tone hearing threshold ...
