Description
Technical field
The present invention relates to audiology apparatus field, in particular to a kind of dress for objectively simulating and regulating and controlling real ear hearing state
It sets and method.
Background technique
For the patient of the dysaudias such as hearing impairment or tinnitus, it usually needs apolegamy hearing aid or tinnitus sound therapentic
Instrument, these devices are all voice signal to be input to the purpose of human ear realizes rehabilitation.During apolegamy, dispenser's ginseng
Patient's audiogram is examined, match system is tested in the importing of hearing diagram data, then adjusts the acoustic gain of input, patient itself then passes through master
Reaction is seen, informs whether the size of dispenser's sound is suitable, but this subjective description is often inaccurate, will affect actual listening
Effect.
It is currently to be measured by the output of the simulated sound in the coupler and ear simulator of standard, still, standard
Coupler and ear simulator differ widely after all with our true ears because the hearing of each Deaf and Hard of Hearing Talents is not
With (or even the hearing of the left and right ear of same patient is all different, i.e., the left ear of tinnitus patient and auris dextra are to the quick of different frequency sounds
Sensitivity and the sound pressure level for causing perception to respond are different), so, such test result is also less objective.
So, not only objective but also safely voice signal is accurately passed to left ear how under the premise of protecting patient's hearing
Or auris dextra and it is passed to ears simultaneously, it realizes hearing or managing irritating auditory phenomena, is the technical problem for needing to solve at present.
Summary of the invention
The object of the present invention is to provide a kind of device and method for objectively simulating and regulating and controlling real ear hearing state, by
A complete artificial ear is established between sound and individual auditory organ and tests match system, and the acquisition of collection data receives, measurement, feedback
Regulation, codes match are integrated, and hearing loss or tinnitus patient can be helped quickly and safely to match out suitable sound waveform,
More accurately Sound stimulat and Auditory Perception are obtained with smaller sound pressure level, while protecting auditory function, is realized more preferable more aobvious
The effect of the rehabilitation of work, is at least able to solve one of above problem.
According to an aspect of the invention, there is provided a kind of device for objectively simulating and regulating and controlling real ear hearing state, packet
Sound playing system, external auditory canal body support frame, DSP processing system and computer are included, sound playing system and DSP processing system connect
