Effect of Loudness Recruitment on Delayed Speech Feedback

Abstract

Ten subjects in each group of a normal hearing, a labyrinthine-hydrops, a masked-normal-hearing, an otosclerotic, and a plugged-normal-hearing group, were studied for the effects of delayed speech feedback at sensation levels of 0, 10, 20, 30, 40, and 50 db, relative to spondee threshold. High median error scores in the hydrops and masked-normal groups were presumably due to the presence of recruitment. High error scores in the otosclerotic group remained unexplained.
