Pure tone delayed auditory feedback. Effect of hearing loss on disruption of tapping performance.

Abstract

Pure tone delayed auditory feedback audiometry was administered to 20 veterans with normal hearing at 1 kHz and a sensorineural hearing loss associated with noise exposure at 4 kHz. Absolute and relative time errors as well as pattern errors were analyzed for the group and for each individual. Mean data showed no difference between error measures for the two frequencies. However, individual data revealed that errors in the subjects' performance occurred at a level slightly closer to threshold at the frequency with the hearing loss (4 kHz) than at the frequency at which hearing was normal (1 kHz).
