Carry out hearing screening method of the present invention
In one embodiment, testing person's desire is carried out a kind of hearing screening method of the present invention to the testee, and with reference to the 1st figure, detailed process is following:
The testee carries out the hearing screening when wearing the hearing aid utility appliance, during owing to use microphone input mode, the optimum distance of osophone and artificial electronic ear surpasses this distance in about 2-3 meter, and hearing aid effect just begins to reduce.Therefore, the preset distance of this detection method is set at 2 meters, the distance of subsequent step is then successively decreased successively, be respectively 1 meter, 50 centimeters, 25 centimeters (alternative this distances of omitting), and 12 centimeters.
Under different measuring distances, understand testee's discovering and identification capability key sound from the low frequency to the high frequency fast.With double reaction correctly is principle, recording mode with initial (have only 1 time respond/3 times), unstable (the 1st time and the 3rd time respond or respond for the 2nd and the 3rd time/3 times), stable (the 1st and the 2nd time double all respond/3 times), four kinds of degree reaching and fix (continuous 3 times all respond/3 times) distinguish.
The carrying out of hearing screening can be subdivided into branch ear (left ear monaural, auris dextra monaural) or ears, for example, if testee's ears all wear osophone, can be earlier with about two ear osophone switches all open, carry out the binaural listening screening; Again left ear osophone is turned off, carried out the screening of auris dextra hearing; Afterwards, again the auris dextra osophone is turned off, left ear osophone is opened, carry out the screening of left ear hearing.So, accomplish the hearing screening of left ear monaural, auris dextra monaural and ears.
Step 102: send any key sound in the octave Chinese sound inspection table by testing person's spoken language, for example/and u/, 2 meters of position of articulation and testee's distances.
Step 104: the testee then makes a response key sound/u/ as if hearing, for example raises one's hand or covers to read aloud, and write down reaction result by testing person.Testing person then sends another key sound under same distance, for example/A/, the testee makes a response.Repeat this step 102～104, all key sound test of octave Chinese sound inspection table is finished.
Step 106: if the testee is under 2 meters distance; For wherein not reaction of certain or some key sound; For example
reached/not reaction of s/; Then testing person with position of articulation and testee's distance be decremented to 1 meter and send
and/s/; Order is not limit, and tests.If the testee is under 1 meter distance;
responded; But for/still not reaction of s/; Then behind testing person's record
reaction result; Continue and to send/s/ apart from successively decreasing half the (promptly 50 centimeters, 25 centimeters, 12 centimeters), test.This distance is successively decreased, and can if still fail to produce reaction in minor increment, finish test successively to 12 centimeters of minor increments, and record testee reaction.
Step 108:, can obtain key sound and detect tables of data, shown in the 2nd and 3 figure with the corresponding result's of distance hearing by above-mentioned screening step.Repeat above-mentioned hearing screening method at interval down at certain hour, can obtain a plurality of hearing and detect tables of data, repeat the restriction especially of the time interval of this screening, for example once a day, weekly or other desired interval.Implement for the first time the hearing that the hearing screening obtained and detect the initial baseline that tables of data can be used as the testee, detect tables of data with the hearing of follow-up screening and compare, whether the audibility that then can be used for assessing the testee improves or regresses.
Furthermore, hearing teacher can be with reference to octave Chinese sound inspection table key sound testing result, as octave discover or identification (picture is pointed out) result in correlated frequency zone corresponding relation, confirm whether the frequency modulation of setting and artificial electronic ear of osophone suitable.The hearing aid utility appliance is if having adjustable control circuit and sound effect circuit; Hearing teacher can propose to set and change or the frequency modulation suggestion to the technician; Or adjust the setting of hearing aid utility appliance voluntarily; Like the sound effect circuit (like the volume of osophone) of hearing aid utility appliance, or the Programmable Logic Controller of hearing aid utility appliance (like the frequency modulation of artificial electronic ear), more to meet user's demand.
