title: Evaluation of Speech-Perception Training for Hearing Aid Users: A Multisite Study in Progress.
abstract: Following an overview of theoretical issues in speech-perception training and of previous efforts to enhance hearing aid use through training, a multisite study, designed to evaluate the efficacy of two types of computerized speech-perception training for adults who use hearing aids, is described. One training method focuses on the identification of 109 syllable constituents (45 onsets, 28 nuclei, and 36 codas) in quiet and in noise, and on the perception of words in sentences presented in various levels of noise. In a second type of training, participants listen to 6- to 7-minute narratives in noise and are asked several questions about each narrative. Two groups of listeners are trained, each using one of these types of training, performed in a laboratory setting. The training for both groups is preceded and followed by a series of speech-perception tests. Subjects listen in a sound field while wearing their hearing aids at their usual settings. The training continues over 15 to 20 visits, with subjects completing at least 30 hours of focused training with one of the two methods. The two types of training are described in detail, together with a summary of other perceptual and cognitive measures obtained from all participants.
