Amplitude modulation (AM) is an important temporal cue for precise speech and complex
sound recognition. However, functional decline of the auditory periphery as well as
degradation of central auditory processing due to aging can reduce the salience and
resolution of temporal cues. Age-related deficits in central temporal processing have
previously been observed at more rapid AM frequencies and various AM depths. These
centrally observed changes result from cochlear changes compounded with changes along …
