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.

Nous décrivons une épreuve qui a pour but de quantifier l'handicap auditif (QUAH). Le test QUAH est un test audio-visuel et psycho-moteur qui comporte 25 questions et qui essaie de recréer les situations auditives de la vie quotidienne. Nous avons effectué le test chez 53 sujets normaux, utilisant plusieurs rapports signal de message/signal concurrentiel; les résultats nous ont montré qu'un rapport égal à 0 dB était la condition standard à retenir (étant ni trop facile, ni trop difficile).

La méthode QUAH semble bien ětre un instrument d'expérience prometteur pour préciser l'handicap auditif. Des éludes supplémentaires sont cependant nécessaires afin d'établir la relation entre QUAH et 1) les mesures audiologiques cliniques et 2) les autres indices plus traditionnels de l'handicap auditif.
