1. Under U.S. OSHA regulations, the Permissible Exposure Level (PEL) of occupational noise is 90 dBA for eight hours and equates to 100% dose exposure.

(a) 90%
(b) 85%
(c) 50%
(d) 95%

2. Do some workers risk puncturing their eardrums with insert type ear plugs?

(a) Yes, you must be very careful not to push the earplug in too far.
