Abstract
Objective:This study was aimed to observe the effects of wireless audio microphone on hearing aids effect in noise at different listening distances. Method:Twenty-three subjects with bilateral sensorineural hearing loss, including 17 males and 6 females were fitted with binaural hearing aids. These patients did sentences recognition tests at two different listening distance（1.5 and 3 meters） in noise. The subjects were tested under three conditions, ①with hearing aids alone; ②with the wireless audio microphone alone; ③with hearing aid microphone and mini audio microphone simultaneously. Result:The sentence recognition threshold at 3 meters listening distance is significantly higher than it at 1.5 meters listening distance with hearing aids alone（P<0.05）. There is no significant difference in the sentence recognition threshold between two listening distances when the wireless audio microphone was switched on（P>0.05）. Conclusion:Mini audio microphone can significantly improve hearing aids effect in long distance listening in noise.
