Repeatable step S17 to S19, until having detected the maximum intensity of test strength range, the present embodiment 110
Decibel.In addition, if it is correct to respond, the test tone of this audible decibel of tester is represented, can be directly entered
Step S20.Hold, whether step S17 to S19 detection testers can hear the test tone after increase intensity,
Therefore other details content refers to step S11 to S13, it is not added with repeating in this.
Step S20：According to the result responded, calculating obtains a Hearing Threshold of first frequency.
Judge module 33 can obtain just listening for first frequency according to the result or accuracy of above-mentioned response, calculating
Force threshold, for example, can according to the minimum test intensity that can be heard, such as corresponding to 250 hertz,
The response of 10 decibels of testing stimulus is correct, and corresponding to 250 hertz, time of 0 decibel of testing stimulus
Mistake is should be, now, the Hearing Threshold that can assess tester in 250 hertz is 10 decibels.
Certainly, after identical frequency and intensity also repeat operation repeatedly, then the accuracy of all responses is integrated,
And calculating obtains the Hearing Threshold of the test frequency, and the number of repetition of testing stimulus, mode and Hearing Threshold
Calculating, be well known to those skilled in the art, do not repeated one by one in this.
As it was previously stated, first frequency can be test frequency (250,500,1000,2000,4000,8000
One of hertz), in other words, can be by repeating the detection side of pure-tone audiometer as shown in Figure 2
Method, to obtain tester for other each (500,1000,2000,4000,8000 hertz of test frequencies
Hearing Threshold hereby).After the Hearing Threshold of each test frequency is obtained, judge module 32 can be further
Audiogram is produced, as shown in figure 4, Fig. 4 is the pure tone acquired by according to the detection method shown in Fig. 2
Audiogram.Wherein, Fig. 4 abscissa be each test frequency (250,500,1000,2000,4000,
8000 hertz), and ordinate is then Hearing Threshold of the tester for the test frequency.Wherein, this reality
The sound broadcasting module 10 for applying example is earphone pattern, therefore can detect the left ear of tester, auris dextra respectively in not
With the Hearing Threshold of test frequency, for example, in 250 hertz of test tone, the auris dextra of tester is audible
More than 70 decibels of sound, the sound of left audible more than 40 decibels of ear.
In addition, it should be noted that, first intensity of the present embodiment is to test the median (50 of strength range
Decibel) exemplified by illustrate, if step S13 judge respond be it is correct, reduction intensity continue step S14 extremely
S16；If judging to respond for mistake, increase intensity and continue step S17 to S19.In other embodiments,
First intensity can also be the maximum (110 decibels) of test strength range, if step S13 judges to respond
It is same to provide more low intensive second testing stimulus with the step S14 to S16 that continues to be correct；If judging back
Mistake is should be, in addition to it directly can calculate the Hearing Threshold of first frequency, may further provide the 3rd test
Stimulate, and the 3rd test swashs has one the 3rd frequency, and the 3rd frequency is similarly above-mentioned test frequency wherein
One of, it is only necessary to differed with first frequency, such as 500,1000,2000,4000,8000 hertz.
Similarly, the first intensity can also be the minimum value (- 10 decibels) of test strength range.If step S13
Judge that it is correct to respond, and in addition to it can calculate the Hearing Threshold of first frequency, may further provide the second survey
Examination stimulates, and the second test swashs has a second frequency, and second frequency is similarly its of above-mentioned test frequency
One of, it is only necessary to differed with first frequency, such as 500,1000,2000,4000,8000 hertz；
And if judge to respond for mistake, the 3rd testing stimulus for providing larger intensity continues step S17 to S19.
In summary, according to the present invention pure-tone audiometer detection method and detection means, its by provide not
(first) testing stimulus of same type is to tester, such as different types of test tone, that is, varying number
