Room acoustics


How about a thread on room acoustics and ways to improve the in-room performance of your system and its speakers? Subjects covered could be the physics of room response, measurement of response in your own room, and how to deal with imperfections, above and below the Schroeder frequency, like damping, bass traps, speaker positioning, (multiple) subwoofers, and dsp equalization. Other subjects could be how to create a room with lower background noise for greater dynamic range, building construction, or what to do in small rooms.
I am a bit busy just now, but as soon as I have time I will try to kick off with some posts and links.

Thanks very much. This is interesting. You can clearly see that things get dirtier below the Schroeder frequency, even with your orange tree (wish I could have them in our climate). If and when you use a computer as a source, you could use it to equalize the low frequency response. If you like that, you could get a miniDSP to do the same with other sources.
I also like the clean decor, but yes hard surfaces like glass windows also make for a dirtier response. No equalization will help you there, only soft surfaces etc. There are some minimalist looking slotted panels etc that apparently dampen mid and high frequencies (often used in modern meeting rooms).
What I find particularly interesting are all the frequencies below 20 Hz.. I start my sweep at 20, so where is everything what coming from?
now you know why some guys bring big leafy plants to shows...and put them in the corners and the hotspots of their room...
