The Effects Of Hearing Aid Circuitry And Speech Presentation Level On Acceptance Of Background Noise, Ashley Powers Boynton
The Effects Of Hearing Aid Circuitry And Speech Presentation Level On Acceptance Of Background Noise, Ashley Powers Boynton
Doctoral Dissertations
The present study investigated the effects of hearing aid circuitry and speech presentation level on ANL and hearing in noise in 19 adult, bilateral hearing aid users. The acceptable noise level (ANL) procedure was used to assess acceptance of background noise. Conventional ANLs (i.e., measured at the participant's most comfortable listening level (MCL)) and ANLs at eight fixed speech presentation levels were obtained. Then global ANLs (i.e., ANLs averaged over eight fixed speech presentation levels) and ANL growth (i.e., the slope of the ANL function) were calculated Each measure was obtained in three conditions: unaided, aided with wide dynamic range …
The Effects Of Asymmetric Directional Microphone Fittings On Acceptance Of Background Noise, Jong Sik Kim
The Effects Of Asymmetric Directional Microphone Fittings On Acceptance Of Background Noise, Jong Sik Kim
Doctoral Dissertations
The present study investigated the effects of asymmetric directional microphone fittings (i.e., an omnidirectional microphone on one ear and a directional microphone on the other) on speech understanding in noise and acceptance of background noise in 15 full-time hearing aid users. Subjects were fitted binaurally with four directional microphone conditions (i.e., binaural omnidirectional, asymmetric right directional, asymmetric left directional and binaural directional microphones) using Siemens Intuis directional behind-the-ear hearing aids and comply earmolds. The results revealed that speech understanding in noise improved when using asymmetric directional microphones compared to binaural omnidirectional microphone fittings and were not significantly hindered compared to …
