When hearing the corresponding minimum sound of a certain Frequency point, voluntarily confirmation or operator assist confirmation, are switched to another ear
Or next Frequency point continues to test, and realizes that helix stream in left and right follows setting Frequency point to be tested, realizes universal newborn hearing screening, process is such as
Attached drawing 2；
Experimental calibration, the laboratory apparatus device of use include but is not limited to silencing case, noise generator, noisemeter, pure tone
Generator and audio recipient, into silencing case input include but is not limited to pure tone standard noise or it is mute under (such as 30dB)
Audio signal (Fm, Xi) export the audio (Fm, Yq) that is influenced by environmental noise at given environmental noise Zn, establish data
Function Yq=W(Fm, Xi, Zn) correspondence noise correction database, wherein Fm is sound frequency, and Xi and Yq are that sound is rung respectively
Degree, Zn is environmental noise loudness, and W is digital function relationship；
Noise correction or acoustic calibration deposit the audio data (Fm, Yq, Zn) measured under environmental noise Zn with disease screening instrument
The database of storage compares, under can finding with (Fm, Yq, Zn) corresponding unique standard mute (such as 30dB A)
Pure tone (Fm, Xi)；
The processing of test result, test result automatically generate including but not limited to audiogram after system is handled, will
The external printing of audiogram or the preservation of memory record or network are uploaded to given server, establish large database concept, cure for higher level
Institute or expert clinical reference, statistics use (as shown in Figure 5), constitute classification medical treatment system, and audiogram is literary using picture
Shelves format, to record preservation and output printing.
Experimental calibration process embodiments:
The given frequency M of Fm, m=1,2 ..., by the standard pure tone of (such as 30dB A) under squelch, loudness Xi, i=
1,2 ... I is placed in environmental noise Zn, n=1,2 ... N, records " tonal signal " interfered by environmental noise eavesdropped
Loudness Yq, q=1,2 ... Q；Obtain a series of experiments detected value, Yq=W(Fm, Xi, Zn), this nonlinear function
May be very complicated, but have one-to-one relationship；
Experiment obtain four parameters between mass data, Fm according to standard pure tone detect frequency modification are as follows: 125,250,
500,750,1000,1500,2000,3000,4000,6000,8000Hz are incremented by step in the range 120dBHL of loudness Xi and Yq
Length can set or be reduced to 5dBHL；
Experimental data base is stored in disease screening instrument memory, establishes database according to following layout: under setting Zn, giving Yq,
Xi at different Fm；
When practical screening hearing, the noisemeter of disease screening instrument configuration measures living environment noise Zn；
Under living environment noise Zn, the audiogram (Fm, Yq) that measures；
The database that data measured (Fm, Yq, Zn) is stored with disease screening instrument is compared, can find with (Fm, Yq,
Zn) the pure tone (Fm, Xi) under corresponding unique standard mute (such as 30dB A).
In conclusion a kind of mobile quick universal newborn hearing screening instrument that the utility model is pointed out, easy to operate, it can be with coupling collar
The size of border noise and the minimum loudness of subject's actual test, calculate or calibrate out one and meet hearing test standard requirements
Pure-tone audiometer threshold value, loudness can be adjusted by non-hearing test professional oneself, institute is defeated by audio tones signal generators
Signal out is converted to corresponding test tone, carries out hearing test to subject, solves traditional specialty hearing test occupancy
