Where to start with room acoustics


I just moved into a new house that has a listening room (13 ft x 27ft with 8 1/2 ft ceiling). It is obvious the room needs some help. I have read some of the chapters in Master Handbook of Acoustics by Everest (although some of it is over my head). The question is how to assess the needs for this room. Where should I start?

The obvious first steps are:

- speaker placement & listening position: you should learn about bass reinforcement and how the position of the speakers and listening chair can null or reinforce certain frequencies. There are several web sites with Java programs to visualize this for you. Just search. Also, be very "true" with the distance from each speaker to your chair, also make sure any toe in is the same for both sides. Use a ruler and be precise.

- 1st reflection points: use the old mirror trick to dampen 1st reflection points on the side walls. The room may also benefit from looking at secondary points as well, like windows, floors, ceiling. Just don't overdo it. An overly dead room is just as bad as an overly lively one.

These 2 simple things should fill your time nicely. If things don't sound right to you after this, then I would suggest investigating other options. These 2 are (mostly) free and just take time.

Enjoy,
