MMM shows how everything actually sounds. A sweep is a very short, single point measurement. A lot of peaks and valleys won't fully fill in until sound actually fills the room. We also rarely keep our head in the same position. So adjusting for that is crucial.You mean you want me to leave the microphone in place, use the same filters, and perform the same sweep a few times with the only variable being sofa present or not? Yeah, I can do that.
I have read links about MMM, but it has never been clear to me what they are trying to accomplish. It would seem to me that it would average out some frequency bands more than others, namely short wavelengths, and I suspect that how much averaging depends on how far you move the microphone. I guess I could resolve all these questions by performing the experiment myself and seeing what the results are.
I've used it a lot if a particular song seems to have some weird behavior and is triggering a resonance or something that sounds odd.
This is why we use pink periodic noise.
