testing for acoustics

Posted: Wed Jun 27, 2007 1:30 am

Im new here, but I have looked through many past post to learn more about audio engineering, thank you. So far I have learned from this site and other sources that within a room you want flat frequency response, that is naturally created by a combination of absorbtion, diffusion, and reflection. Here is my question, how do you test a room to determine where to apply special needs, I have an idea but to get the best flat frequency; How do you test the room, are their special meters I need to buy or rent? With that, is it best to test different areas of the room then to check or? Help is very very appreciated.

Thanks in advance

One of the acoustic treatment sites (REAL Traps I believe) has a downlaodable file containing test tones in MP3. Burn a CD from it and you WILL BE AMAZED !

Agreed. The test tone CD on the RealTraps site is mainly for "audiophiles" and home theater people who don't have a computer connected to their audio system. If you do have a computer connected, the Room EQ Wizard Glenn linked to (or ETF or FuzzMeasure) is much better and gives much more information than simple test tones.
