wondering..db versus room

[CoolCat]

so as I understand it, please correct me if I'm wrong, but the 90db is where the freqs reach the equal volume point or "flat".

but in a crap room, HR, this loud volume creates the nulls, nodes, dips and mountains of adding and subtracting freqs... ass sound, in short.

So which would be better to lower the volume, to reduce the "room effect" or keep the 90db ??

Why would that be bad, from a mathematical standpoint, the ratio of "sound bouncing" would be reduced if the volume was lowered, in turn actually making the "sound" closer to flat than at the 90db level?

I expect for a given speaker and listener placement the room does what it does pretty much without regard to volume. Near-field or tight dispersion gets you a little better direct to room ratio.
Could be wrong.

so the room is still doing the same thing to the sound, no matter what volume? For example, are the reflections off the back wall the same no matter what the volume is?

Pretty much. I have never measured a change in room response with a change in volume, and I measure my room very frequently. Well, technically I am measuring microphones, but the room is always there too.

That's not to say there isn't some effect, but at a range of normal volumes, say 70dB to 100dB, I've never seen it, and I don't know a physical mechanism to explain a difference if there was one.

IMO, it will lessen the affect, although not a great deal. But then you have other problems. The quieter you play bass or treble, the more mid they sound.

so 80-85 db takes precedence, as I read the responses.

in short, set the volume and fix the room to accommodate...

thanks for the answer.

Yup. Obviously mix at different levels for reference, but 85dB is where our hearing is flattest, i think.
