Abstract:

The theoretical considerations of the localization function utilizing time delays have been extended to other areas of acoustics to provide a comprehensive theory useful in explaining speech recognition, attention, and the importance of reverberation on speech intelligibility, acoustic coloration, noise masking, and other phenomena. The knowledge of speech recognition was used in initial work to establish inter-species communication with the porpoise.
