title: Competing Speech Perception in Middle Age.
abstract: OBJECTIVE
  This research forum article summarizes research from our laboratory that assessed middle-aged adults' ability to understand speech in the presence of competing talkers.
  
  
  METHODS
  The performance of middle-aged adults on laboratory-based speech understanding tasks was compared to that of younger and older adults.
  
  
  RESULTS
  Decline in the ability to understand speech in complex listening environments can be demonstrated in midlife. The specific auditory and cognitive contributors to these problems have yet to be established.
  
  
  CONCLUSIONS
  There is evidence that the ability to understand a target speech message in the presence of competing speech messages changes relatively early in the aging process. The nature and impact of these changes warrant further investigation.
