WebbStandard threshold shift (STS) is the criteria recommended by OSHA for early detection of NIHL. There are limited studies on STS and hearing conservation programs in Thailand. The objective of this study is to estimate the incidence of the industrial workers who acquire STS. Methods: A retrospective descriptive was performed.

WebbA Standard Threshold Shift, or STS, is defined in the occupational noise exposure standard at 29 CFR 1910.95 (g) (10) (i) as a change in hearing threshold, relative to the baseline audiogram for that employee, of an average of 10 decibels (dB) or more at 2000, 3000, and 4000 hertz (Hz) in one or both ears. 1904.10 (b) (2) WebbHere are some common examples of decibel level and recommended maximum exposure: 85 dB - 8-hour exposure limit (according to OSHA) 100 dB – 15-min exposure limit 110 dB – 1-min exposure limit 2.
