Hmmm... Clean 124 dB? How on earth could one tell inside a hotel room? Depending on what standard you want to adhere to, hearing damage at that level is predicted to occur with exposure duration of between two minutes and three seconds. (If I did the arithmetic right.). I'm guessing that a human ear will distort the perceived sound even before any injury takes place.
Yeah, I'm being a wet blanket. But, it's probably not so fun to be a deaf audiophile.
