Hearing threshold and/or hearing state detection system and method

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 ...

Problems solved by technology

However, there is no input-output (I / O) function detection related to stimulation frequency otoacoustic emissions, nor does it involve the detection technology and method of using SFOAEs I / O function to estimate the hearing threshold and hearing condition screening of the auditory system; The name of the invention is a stimulus frequency otoacoustic emission tuning curve detection and calibration system. It only discloses the detection method of the stimulation frequency otoacoustic emission suppression tuning curve and the detection technology of the calibration system, but does not involve the use of stimulation frequency otoacoustic emission. The detection technology and method of hearing threshold estimation based on input and output functions; the prior art discloses an auditory sensitivity detection system based on stimulation frequency otoacoustic emissions, and discloses the detection of intensity sensitivity by using the waveform shape of each point of SFOAEs, and the use of stimulation frequency The waveform shape of each point of the otoacoustic emission suppression tuning curve is used to detect the frequency sensitivity, but there is no method such as using the input-output function curve of the otoacoustic emission at the stimulation frequency

[0005] In summary, some of the existing technologies do not detect the hearing threshold, and some do not use the complete information of the input and output functions of the stimulation frequency otoacoustic emission to detect the hearing threshold, and the accuracy of the hearing threshold detection result is not high.
