The effects of Hearing Aid Digital Signal Processing Settings and Cognitive Processing Speed on Speech Recognition performance tasks in Adverse listening conditions in Elderly hearing impaired listeners
2015 (English)Conference paper, Poster (Other academic)
Previous studies have demonstrated that speech recognition in noise is associated with hearing aid compression release settings and cognitive processing speed. This study investigated the effects of Cognitive processing speed and Digital Signal Processing settings (linear amplification without noise reduction, linear amplification with noise reduction and non-linear amplification with (fast-acting compression without noise reduction) on the performance of speech recognition task in noise in elderly hearing aid users. Two hundred elderly (mean age = 61 years) experienced hearing aid users with sensorineural hearing loss participated in the study. Individual measurements of Cognitive processing speed (rapid automatic naming test), Speech recognition in noise (Hagerman test) were obtained and used to predict a successful outcome. The results will be presented and the potential clinical implications in the rehabilitations of elderly hearing aid users discussed.
