Seven methods of hearing loss prediction from acoustic reflex data were compared in 225 adult subjects. The prediction methods were two versions of Sensitivity Prediction by the Acoustic Reflex (SPAR), four regression equations and a bivariate plot technique. Accuracy of hearing prediction varied significantly among methods. Hearing loss was identified most(More)
The amount of temporary threshold shift (TTS) measured in a particular individual is dependent on several factors. One such factor is the pre-exposure hearing level of the subject. In this study, the contribution of this factor to the measured TTS was examined in 8 normal-hearing subjects. TTS measurements were made in unmasked and masked conditions(More)
