Note

In the study by Ng et al. (under review), noise reduction reduced the adverse effectof irrelevant competing speech on memory for target speech for people with hearingimpairment. In the present study, we investigated the effects for persons withhearing impairment on memory for target speech heard against a backgroundof competing speech of 1) noise reduction in hearing aids; 2) the semantic contentof the competing speech; and 3) the role of individual differences in workingmemory capacity. Binary time-frequency masking technique (Wang et al., 2009),which is a noise-reducing signal processing scheme, was used. A free recall memorytask was administered to 26 experienced hearing aid users with symmetricalsensorineural hearing loss. In this task, target sentence lists were presented ina competing speech background, either in a familiar language (Swedish) or inan unfamiliar language (Chinese).Working memory capacity was measured usinga reading span test. Results showed that recall performance was poorer whenthe language of the competing background was familiar compared to unfamiliar.When noise reduction was applied, the effect of familiarity of language was nolonger significant. Noise reduction improved memory for words heard in noise. Inparticular, such improvement occurred in the late-list position. People with betterworking memory had better memory performance in the early- and mid-list positionsthan people with poorer working memory. Better recall of earlier-list items inpeople with good working memory capacity reflects more efficient encoding intolong-term storage.
