The "Safe" Workday Noise Dose.
Noise, Shock and Vibration Conference, Monash University, Melbourne 1974:19-27
Rationale are discussed for varying proposals for permissible 8-hour exposures to industrial noise. Levels of 80 decibels are determined to be safe, while 90 decibels can cause permanent threshold shifts in susceptible individuals. Analysis using the 5-decibels-per- halving-time relation is shown to be more accurate than the 3- decibel trading relation of the total-energy theory.
