简要总结
This study will compare far-field speech understanding in noise using a hearing aid alone, with using a hearing aid plus a Roger remote microphone. It will also compare the HA+Roger mic to two other manufacturers' hearing aids plus remote mic systems in the same condition.
详细描述
This study will recruit 15-20 hearing impaired experienced hearing aid adult users. Participants will be fit with three sets of hearing aids (Phonak devices, plus two competitor devices) and the associated remote microphone from each manufacturer. Speech perception will be measured using the validated AZ Bio test, and will be given in both the hearing aid alone condition, as well as the hearing aid plus remote microphone condition. The participant will be seated in the center of a room approximately 7m by 5.25m with a loudspeaker approximately 3 m away, at 0 degree azimuth. Four loudspeakers will also be placed in the corners of the room. For the quiet condition, target speech will be presented from the loudspeaker in front of the participant, for the noise condition speech will be presented from the front with speech babble presented from each of the corner loudspeakers. The speech understanding score in both quiet and in noise will be measured for hearing aids alone, and hearing aids plus the appropriate compatible remote microphone.
