Let me also add the following: While I forget the actual dB number that's supposed to be the line for hearing damage, whatever that number is I call BS. The reason is we have people with all sorts of hearing tolerances effected by things like: Age. Amount of sleep. Illness such as colds, chronic allergies, etc. Any current hearing damage and/or where an individual is along that path toward hearing loss or weakness. Other, mostly health-related, variables. For example, someone who's been playing in loud night clubs, standing within 5 feet of the drummer's cymbals on small stages for 30 years is pretty likely to have a much lower tolerance for further hearing damage over a shorter period of time. How many times have YOU been slammed with monitor feedback so far, and at what frequencies and for how long? Damage occurs in milliseconds. IIRC, that tolerance is rated somewhere around 88dB over an 8 hour period, correct? Regardless, someone as I described above may now be realizing continued hearing damage at lower dB ratings over shorter periods of time, so I wouldn't trust just going by that. Feels great when the volume hits you in the chesticals and compresses your eardrums, ain't it? Notice how your ears feel when you lay down to go to sleep after an evening at a rock concert? You should feel better by morning at the latest, but your hearing is slowly eroding away from that. Do it enough times over months or years and you will see some loss on the charts. Lastly, get your hearing checked at least once a year. .
