Abstract

Temporary changes in hearing of the subjects were monitored with distortion product otoacoustic emissions (DPOAEs) after control sound exposures in a laboratory. The objectives of the experiment was to investigate whether the +5 dB penalty for impulsiveness used in international standards and legislation correlates to a higher risk of hearing damage. Subjects were exposed to two types of binaural recordings consisting of a continuous broad-band noise-exposure normalized to LEX,8h = 80 dBA and the interaction of the previous stimulus with a noise of impulsive character normalized to LEX,8h = 75 + 5dB penalty = 80 dBA. The results shown that the effects on DPOAE levels from the two stimuli could be compared in terms of their total acoustic energy.
