Document Summary

Physical agents: sources of energy that may cause injury or disease. Human hearing range is between 20hz-20,000 hz (cid:271)ut othe(cid:396) f(cid:396)e(cid:395)ue(cid:374)(cid:272)y that hu(cid:373)a(cid:374)s (cid:272)a(cid:374)"t hea(cid:396) (cid:272)a(cid:374) (cid:272)ause hea(cid:396)i(cid:374)g da(cid:373)age. Decibels (db): 3 db difference is 2x the loudness; 10db is 10x; 20db is 100x. Construction workers, cafeteria workers more at risk of early warning change (loss of hearing in the upper frequency) Sound considered to be noise by one individual may not be noise to someone else. Human hearing response conditional on 3 characteristics: frequency, duration, loudness.

Cause startled response to loud, unexpected noise, cardiovascular, biochemical changes, nausea, headaches.
