Article-I.D.: cbosgd.3193 Posted: Mon Feb 28 17:03:24 1983 Received: Tue Mar 1 05:55:12 1983 References: <526@cwruecmp.UUCP> Speaking of loud music, does anyone have documented information on noise levels that it takes to cause hearing loss, either for a one-time thing (as in going to a rock concert) or continuous (the guy who tears up streets with a jack hammer for a living) or whatever? Specifically, I'd like to find out if there is any chance of damaging my son's hearing (he's going on 4 months old) when he's sitting in the back seat of the car and I have the stereo (bass speakers in the rear doors, treble in the front) up loud enough to overcome road noise on the freeway. (By the way, I'm not real fluent in what the heck a dB is anyway, I would personally appreciate a brief explanation with some sample noise levels, and maybe a method of measuring the noise level.)
