Spatial Hearing, Attention and Informational Masking in Speech Identification
Abstract
The specific aims of this research grant included examining how and how well listeners could treat the two ears as independent channels, the role of a priori knowledge in multisource listening, and the evaluation of the Listener Max-Min observer models in multiple talker environments (Durlach et al., J. Acoust. Soc. Am., 2003). The general approach was empirical using humans subjects as observers in masked speech identification experiments when multiple sources of sound were present and, usually, were spatially distributed. As a general statement, we feel that considerable progress was made toward each of these aims. A list of publications and presentations at scientific meetings is appended. The work that was accomplished with AFOSR support has considerable scientific significance and possible relevance for practical applications. Furthermore, it has stimulated new lines of research in auditory attention and masked conditions where higher-level cognitive processes are key.
