title: Quantifying auditory handicap. A new approach.
abstract: This report describes a new audiovisual test procedure for the quantification of auditory handicap (QUAH). The QUAH test attempts to recreate in the laboratory a series of everyday listening situations. Individual test items represent psychomotor tasks. Data on 53 normal-hearing listeners described performance as a function of the message-to-competition ratio (MCR). Results indicated that, for further studies, an MCR of 0 dB represents the condition above which the task seemed too easy and below which the task appeared too difficult for normal-hearing subjects. The QUAH approach to the measurement of auditory handicap seems promising as an experimental tool. Further studies are needed to describe the relation of QUAH results (1) to clinical audiologic measures and (2) to more traditional indices of auditory handicap.
