Abstract:
Objective To compare the effects of speech recognition scores in young normal hearing adults using single-channel adaptive microphone and multi-channel microphone paradigm.Methods 30 normal hearing young adults,15 females and 15 males with a total of 60 ears were fitted binaurally with Diva 9(single-channel adaptive directional microphone mode)and Inteo 9(multi-channel adaptive directional microphone mode).The speech recognition scores were compared as a function of different signal to noise ratios in a diffuse environment.Results The SNR of L50 of single-channel adaptive directional microphone mode was 0.63 dB and that of multi-channel adaptive directional microphone mode was-4.63 dB.There was significant difference between the two microphone setups.Conclusion Multi-channel adaptive directional microphone mode can improve the speech recognition score in noise.
