Objective methods of hearing assessment: A system for recording the crossed acoustic response

Abstract

The development of auditory evoked responses as objective methods of testing hearing is discussed with attention focusing on the 'crossed acoustic response' (c.a.r.) in this role. The instrumentation used to facilitate the use of the c.a.r. in testing neonates and young children is described, and an outline is given on how some of the problems involved in this type of testing have been overcome. © 1976 International Federation for Medical & Biological Engineering.
