WebOSHA (1983) uses the term Standard Threshold Shift (STS) to describe significant changes from baseline hearing levels. The OSHA Standard (paragraph (g) (10)) defines STS as, "a change in hearing threshold relative to the baseline audiogram of an average of 10 dB or more at 2000, 3000, and 4000 Hz in either ear" (OSHA,1983,).
