OSHA uses a 5 dBA exchange rate, meaning that the allowed exposure time is cut in half for every increase in exposure of 5 dBA. ACGIH and NIOSH recommend a 3 dBA exchange rate because noise energy exposure actually doubles every 3 dBA. OSHA explains the use of the 5 dBA exchange rate as a means to account for the time during a workday that the employee is not exposed to noise, like breaks. Imagine you are a safety officer who has to choose which exchange rate is preferable to use at your organization. Discuss in your journal entry whether the 5 dBA or the 3 dBA exchange rate should be used for controlling occupational noise exposure.
