Instructional Procedures for F2F
1. AuthenticityAsk the participants what type of sounds they think are too loud. Write examples on the board.
2. AuthenticitySee if anyone knows how loud is too loud.

OSHA’s permissible exposure limit (PEL) for noise exposure is 90 dBA for an 8-hour TWA and the standard uses a 5 dBA exchange rate. This means that when the noise level is increased by 5 dBA, the amount of time a person can be exposed is cut in half. For example, a person who is exposed to noise levels of 95 dBA (5 dBA above the OSHA PEL of 90 dBA) can be exposed for only 4 hours in order to be within the daily OSHA PEL. See Table D-2 for permissible Noise Exposure.
3. EfficiencyEngagementPlay the sounds on the protect your hearing website. Get participant’s reactions. Is the sound too loud? How do they know?
4. AuthenticityEfficiencyHave participants list (you can write on the board or project on a computer screen) what sounds they encounter during the day and which are ok with and without hearing protection.
