"Normal" sound is an AC signal - the air shakes back and forth. Wind is air that continuously moves in one direction, which could be considered "DC" sound. Just an analogy with electric currents. (Now, how would you rate dB values for "DC" sound?)
If you have ever tested speaker phasing with a battery, you have tested the step response of the speaker. The thump is the AC components of the edge (and there will probably be some noise from contact bounce). If there was a speaker with a frequency response that extends down to DC (impossible with regular speaker technology), it would put out a steady stream of air. (A rotary subwoofer can go down to DC and operate as a fan.)
I used to listen at realistic levels, but it upsets the dog. If I play the Digital Domain CD at a realistic level, he'll poop on the carpet.
Damn, I even placed a link to show you what I meant. AC/DC is a legendary rock band, the type you want to listen them LOUD. Did you understand me now?
@wg_ski - my speakers are having 92dBm, so they're quite sensitive. At 40W the pressure level is 108dB. It's more than enough for me.
Hello Ratza and all
One of those cultural context things I suppose. I used to listen to Stiff Little Fingers and the Undertones a lot when I was younger, and got complaints from neighbours. Just as well we don't have any Transformers fans 🙂 I've added your 'flat out' level to my list, thanks
You forgot that electrical engineers think differently than normal people. And yes, it is true even for the young, pretty ones.
Pushing the db over 85 becomes unpleasant for me. That's in a 12' x 14' room at about 8.5' from the speakers and testing with a ratshack meter. I would guess average listening is about 6 db lower than that. That's a good question.

How loud do I listen? That is dependent mostly on how many beer I consume before approaching the volume knob. My beer muffs interfere with clarity and require that I increase the power exponentially with every 6 pack.
And I was just thinking that I'm the only one who saw that. Even if the avatar of star882 would have been different, I'm still sure she's a woman. Why? Women never take affirmations as they are. They always interpret things, even those which do not need to be interpreted.
star882, I wanted to ask what do you mean by "EE think different than normal people", but in the meantime I found the answer. I had to ask a female colleague of mine if she understands what you said and everything cleared up for me when she started to try to explain... It is actually women EE (my summary after 30 minutes of explanation attempts, no offence).
hahahaha. Fun thread.
I never thought to quantify my optimum listening volume. I listen to live music more then reproducing it at home, so, I guess, if I had to quantify, concert level in a bar. At home it's relative to the time of day, material and my mood...but, usually, it's pretty f'n loud. It's why i got into this hobby, so I can hear every detail, drown out the world and not hurt myself while doing so.

Thanks KevinHeem, that is a useful data point. There seems to be a 'mode' SPL around 80 to 86dB from those who are able to reply with actual numbers.
To continue the electrical analogies, I think the main reason why I'm different is because I have a different "code base" and "hardware" than most of you. Just accept the differences and understand that they often make for a different point of view in engineering. And note that sudden changes in thought really just help at looking at the problem from a different angle. (However, contrary to what you might think, that is not all caused by "interference" from the "415nHz VM input gating clock", although the "falling edge" of that clock does often trigger such events.)
How loud??
ELEVEN"😀
actually, for most casual listening, with others around talking and such... maybe 75 - 80 dB C in a large 2 story great room... when alone, that's a different story... > 100dB @ 12 feet back not out of the realm ...
😱
... that's when the wife leaves the building...

80 to 85 is just fine for normal listening. If I'm playing AC/DC or Manowar, then 120 does quite nicely.(and when I say Manowar, I don't mean the jellyfish)
