Speech Understanding And Listening Effort In Noise With A New Speech Processing Algorithm, Abigail E. Compton
Speech Understanding And Listening Effort In Noise With A New Speech Processing Algorithm, Abigail E. Compton
Dissertations, 2020-current
This study examined the effect of a new speech processing strategy (SpeechZone2) in a commercially available hearing aid on speech understanding in noise and self-reported listening effort. Seven adult, experienced hearing aid users (2 males, 5 females; mean age = 64.6 years) with mild to severe, sloping sensorineural hearing loss participated in this study. Binaural Unitron Flex receiver in the ear style hearing aids with closed domes were used to provide the manufacturer prescribed amplification for each participant. The hearing aids were programmed with two separate memories: 1) omnidirectional microphone without SpeecZone2 processing, and 2) adaptive directionality with SpeechZone2 processing. …
The Impact Of Hair Covering Hearing Aid Microphones On Directional Performance, Sara F. Wagner
The Impact Of Hair Covering Hearing Aid Microphones On Directional Performance, Sara F. Wagner
Dissertations, 2020-current
This study examined the effect of hair covering on hearing aid directional microphone performance. Nine adult, experienced hearing aid users (3 males, 6 females; mean age = 64.6 years) with mild to severe, sloping symmetrical sensorineural hearing loss were included in this study. Binaural Oticon Opn 1 receiver-in-the-ear hearing aids with closed domes were used to provide the recommended amplification for each participant. Speech Reception Threshold (dB SNR required for 50% speech understanding) was measured in all combinations of directional microphone (on/off) and hair covering (with/without) resulting in a total of four conditions. Results showed that directional microphones significantly improved …
