Description
Technical field
The invention belongs to a kind of hearing device, and integrated sound isolating earphone is led more particularly, to a kind of moral character.
Background technology
It is conductance earphone and osophone that hearing test, which needs to use two kinds of earphones, separately below to the feelings of both earphones
Condition is explained.
The hearing test project carried out using conductance earphone is much shown in, such as pure tone air conduction hearing threshold is tested, comfortably with not relaxing
Suitable threshold test and tinnitus detection etc..Conductance earphone most widely used at present has Earphone, cover aural headphone and plug-in type ear
Machine, but some defects all be present in these earphones.Such as：The problem of Earphone presses outside auricle, and it is present master
Have：Frequency response is narrow, leakage sound, duct can be caused to collapse, can not repeating signal, interaural attenuation be small exactly in very short time
And Occlusion effect etc. can be produced.
Although cover aural headphone comfortable wearing, will not cause duct to collapse, leakage sound, interaural attenuation be small and Occlusion effect
Problem could not solve, it is seen that it is leakage sound that a problem, which can all occur, in Earphone and cover aural headphone.
Insert earphone is the earphone for having at present larger interaural attenuation, relative can reduce leakage sound, but because its probe needs
Insert in external auditory meatus, subject has ear foreign body sensation, and every time using must all change earplug, add use cost and
Operating procedure, duct abnormal subject in part can not use, at present clinically using seldom.
It is well known that due to the leakage sound problem of earphone, when the threshold of audibility of the ear of subject two has notable difference, poor one
The stimulation sound for picking up the ears given can be held very big, if volume exceedes minimum interaural attenuation value, the preferable ear of offside hearing will be eavesdropped
To stimulate sound, now subject may take for having heard test signal and having reacted, this will when test structure go out
Existing error.In order to solve the problem of eavesdropping, a kind of method for being called masking procedure audiometry, that is, the ear in preferable side are clinically used
One noise of upper increase, disturbs its hearing to avoid eavesdropping, but this will make testing procedure cumbersome, influences efficiency, and this masking
Requirement of the method for testing to operating personnel it is high, masking deficiency or situation about excessively sheltering can occur in misoperation, to structure
Have a great influence.
Pure tone test does bone conduction test again after typically having carried out conductance test, and the earphone that bone conduction test uses is bone conduction ear
Machine, osophone is to detect the threshold of audibility by the vibration of skull, because of the interaural attenuation very little of bone conduction, so carrying out monaural survey
Need to be sheltered during examination, current operating method is that after conductance test is completed, subject will also put on osophone, so
Sheltered afterwards to wearing conductance earphone on picking up the ears, now subject can feel extremely to feel bad, tested one pick up the ears after again another
One, which picks up the ears, carries out same operation so that cumbersome reduction testing efficiency.
Mentioned in other GBT16403-1996 when the subject's head of bone vibrator and no external ear and Functional Impairment of Middle Ears connects
When touching, sound level that bone vibrator gives off any air answer to being enough to ensure that in real bone conduction threshold level and by bone vibrator induction
There are enough gaps between false gas bone conduction threshold, that is to say, that may be because the vibration of bone vibrator during test and drive surrounding air
Vibration, and tested ear is exposed, and this sound that sends of vibrating can be perceived through air conduction passage by subject, so as to survey
Obtain false bone conduction threshold.
The content of the invention
