WebbIn the United States, OSHA’s standard for significance is a 10 decibel (dB) increase in hearing threshold, averaged across 2000, 3000, 4000 Hz frequency thresholds (29 CFR 1910.95). This 10-decibel decrease is referred to as a “standard threshold shift” (STS); OSHA requires any STS to be reported as a workplace injury. WebbWhenever a worker has experienced a persistent standard threshold shift (STS), it is necessary to determine whether the loss is work related. An STS is a worsening of at least 10 dB in average hearing thresholds for the frequencies of 2, 3, and 4 kHz in either ear compared to the most recent baseline (age correction optional).
