What is the time weighted average (TWA) for sound according to OSHA?
According to the center for disease control, the NIOSH recommended exposure limits
(REL) for noise is 85 decibels over an eight-hour average or 90dBA over the same period. Any
exposure above these levels are regarded as hazardous.
What is audiometric testing and what TWA threshold requiring testing?
Audiometric tests are tests run to determine a person's hearing levels with the assistance
of an audiometer. Audiometric tests also measure the subject's ability to identify different
simultaneous sound intensities and tell speech from background noise. Such tests are used to
monitor a person's hearing ability over time (Cacace and Burkard, 2016).
The threshold limit value - time weighted average (TLV-TWA), which is the
concentration of harmful substances in the atmosphere in a 40-hour workweek, is the TWA
threshold that requires testing to ensure there are no adverse effects to humans exposed to such
environments (Margolis, Birck and Saly, 2011).
How often should an employee have an audiometric test?
