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. …
