Posted By holmezy John, probably being a bit fussy, however, I would put +80% of the emphasis on the employees health and how important it is for them to protect it rather than keep going on at them about discipline. Might be that you typed it wrong or I got the wrong impression!! Give them plenty of info re noise, ie first action level, 2nd action level. Try to relate familiar sounds with various levels, ie normal talk is about 65dBa or so, jumbo jet is +140dBa etc. If you feel confident enough, explain the acute and chronic effects. I try and explain the inner ear and the sensory "hairs" in such a way that a short term exposure just makes them tired, they lay down and have a rest, hence the muffled hearing, but when they've rested, they stand up and way we go again. More exposure at high levels makes them give up totally, so they lay down but don't get back up. Its a bit simplistic and childish but they will remember. Sorry if not alot of help. Holmezy

Posted By Pete Longworth Start off your presentation by mumbling as quietly as you can while still being heard for a few seconds. When someone asks you to speak up (or even if they don't) go on to explain that, that is what normal speech sounds like to someone with noise related hearing loss.
