Abstract
Stud-type attenuators in a widely used model of self-recording audiometer are apt to be associated with transients and intermittencies in the intensity time envelopes of their acoustic output. These resulted in more acute threshold measurements in normal-hearing subjects, and the effect is greater at the higher frequencies in persons with noise-induced hearing loss. Correcting for the effect of these transients results in good agreement between earlier data on normal threshold of hearing and current proposals for application of ISO Recommendation 389 to audiometers using TDH-39 earphones calibrated on 9-A couplers.This publication has 1 reference indexed in Scilit:
