How loud is loud?


Seems like a rhetorical question, but I'm curious what other folks think is "ok, now that's loud"

For me, if something's hitting 100dB as measured from where I'm seated while listening, and not just for a brief moments, but with some regularity, that's loud.

I used to listen at higher average volume than I do these days. Typically, I'm finding that at the right volume, the recording is more nuanced then when it's running full throttle.

If I'm not mistaken, the late Peter Walker observed that every recording has it's one correct or optimum playback level. I think generally he was correct, though once we are willing to forge optimum there's a range of acceptable.

It depends on the recording. Constant high level will numb your ears and reduce dynamics. Rock bands often start at lower volume adding more later. Once I attended concert that was so loud that I could not open my mouth because my lungs were vibrating. I don't want that at home (not to mention my neighbors) and I don't want to be deaf.
Zavato, I agree with your assessment of loud. And I DO enjoy lots of music approaching those levels, or just below; that's where a good system can reproduce the energy of a live performance. I ensure that I'm not disturbing anyone, and carefully limit my exposure to such levels (I'm not a high-hours daily listener). And music rapidly becomes very unappealing as you push beyond this level.

My problem with systems that do low levels well is that they're usually the result of a modified response curve that complements our own hearing's non-flat response curve at those levels -- the Fletcher-Munson curves are oft-referenced here (though they may not be very accurate). That's not a route that I prefer; I like gear that yields fantastic realism at loud levels and is completely non-fatiguing -- so in most cases bright sounding gear doesn't gel with me.
Hey Mulveling,
If you our talking about high end equipment I don,t know of any that still have a Loudness control button. Some cheap equipment have that and it increases low and high end to compensate the drop off in our hearing of bass and treble as volumn goes down which is the Fletcher-Munson curve. remember if your listening to a live concert and volumn gets very low the same fall off of low and high frequencies occur. Regarding what is loud, if after listening to music your ears are ringing it was too loud. You will damage your hearing

Yes, if you experience any fatigue and/or loss of hearing sensitivity after a session, then it was definitely too loud, and care should be taken to not repeat those circumstances. If you ever experience ringing, then it was WAY too damn loud, and permanent hearing damage may have occurred.
When your neighbors slide on their knees and beg for mercy...then it is probably a bit loud.
