Summary of Present Damage Risk Criteria,
Abstract
This summary maintains that in spite of uncertainties and open scientific questions, the available data base is consistent enough to predict for preventive/protective purposes the amount of noise-induced permanent threshold shift to be expected in a population as a result of habitual noise exposure. For noise exposure levels to have no effect on a population's hearing after 40 years of daily exposure, a 'safe' level of approximately 75 dB(A) is derived following the arguments advanced in the EPA 'Levels Document.'
