Comparative Recruitment Testing: An Evaluation of some new and older Methods

Abstract
In the University Ear Clinic, Rigshospitalet, Copenhagen, and the State Hearing Rehabilitation Centre, Copenhagen, we have in recent years had the opportunity to employ various new methods for determination of recruitment of loudness. (Thomsen 1955 and Filling 1957). Lately we have further tried out another method based on the intra-aural muscle reflexes (Terkildsen 1957). In order to obtain an evaluation of the relative value of these methods, a minor series of patients was submitted to all methods available.
