Title Standard threshold shift criteria
Bibliographic information Jan. 1985, Vol.27, No.1, p.34-42. 18 ref.
Abstract Standard threshold shift (STS) criteria were evaluated using techniques borrowed from decision theory and signal detection theory to separate audiometric STS's in true-positive and false-positive shifts. The current OSHA (USA) definition of a "change in hearing threshold relative to the baseline audiogram of an average of 10dB or more at 2, 3 or 4kHz in either ear" and the American Academy of Otolaryngology-Head and Neck Surgey recommandation of a 10dB or greater change for the worse for either the 0.5, 1 and 2kHz pure tone average or the 3, 4 and 6kHz pure tone average in either ear, were supported. Revisions of baselines after an STS occurs are supported.
