However, just a little bit louder(95 db.) is the level where listening time must be restricted in order to prevent hearing loss. I posted OSHA exposure standards previously but if I recieve a few requests, I would be glad to post it again. Keep in mind we are discussing AVERAGE sound pressure levels.
