Abstract

Any complex sound that enters the normal ear is decomposed by the auditory filters into a series of relatively narrowband signals, each of which can be considered as a slowly varying envelope (E) superimposed on a more rapid temporal fine structure (TFS). It has been argued by several researchers that E information is sufficient for good intelligibility of speech in quiet, but that understanding speech in complex backgrounds, especially competing talkers, may require the use of TFS information. Hearing - impaired people appear to have a reduced ability to use TFS information, and this may partly account for their relatively poor ability to understand speech in complex backgrounds. Several studies are reviewed that assess these ideas, using both normal -hearing and hearing -impaired listeners. It is argued that TFS information may contribute to the perceptual segregation of speech from complex backgrounds, but that TFS information is probably not selectively involved in “dip listening”. The ability to use TFS information appears to decline with increasing age from the twenties onwards, even when the audiogram remains normal, and this partly accounts for the reduced ability of older listeners to understand speech in complex backgrounds.
