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.

Keywords

Objective tests of hearing Averaging Crossed acoustic response (postauricular response) 

Sommaire

L'article étudie le développement des réponses auditives évoquées en tant que méthodes objectives servant à tester l'ouïe et en s'attardant en particulier sur la ‘réponse acoustique croisée’ (r.a.c.) dans ce rôle. On décrit les instruments servant à faciliter l'usage de la r.a.c. dans les tests sur nouveauxnés et les enfants en bas âge et on ébauche la méthode permettant de surmonter quelques uns des problèmes rencontrés dans ce genre de test.

Zusammenfassung

Es wird die Entwicklung von durch das Ohr hervorgerufenen Reaktionen als objektive Verfahren zur Prüfung des Gehörs besprochen, wobei sich die Aufmerksamkeit auf die gekreuzte akustiche Reaktion (c.a.r.) in dieser Rolle konzentriert. Die zur Vereinfachung des Einsatzes von c.a.r. beim Prüfen von Neugeborenen und Kleinkindern verwendeten Instrumente werden beschrieben, und es wird umrissen, wie gewisse Probleme, die man bei dieser Prüfung antrifft, gelöst wurden.
