Room Acoustics

How can one create the optimal acoustic room? Is there even any such thing as a best acoustic room setup? Professionals who handle room acoustics would say that while it is possible to improve the room acoustics for an area, there is generally no one 'perfect' room design from an acoustic standpoint. By performing room acoustic calculations, sound engineers try to add acoustic room dividers that change the room acoustic measurements. Room acoustic problems are usually caused when the dimensions of the room make it into a resonator for sounds in a specific frequency range that are given off by something in the area.

With an acoustic room treatment kit, one can prevent the room acoustic problems by using as many distances between sound baffling surfaces as possible. After an acoustic room treatment it should not be possible for bothersome sounds (often these sounds are in the twenty to two hundred hertz range) from outside to resonate across the dimensions of the room. The most common place in which to use these room acoustics techniques (besides a sound studio where room acoustics are taken as a matter of course) is an acoustic conference room, as businesses that have conference rooms are likely to have the money to put into making an environment with strong room acoustics (not that it is generally that expensive as baffling devices are modular, and one can even choose to go with a relatively simple antinoise 'cancellation' device if one wishes). Another kind of room in which one commonly uses room acoustics techniques is an acoustic home room theater; to make a home theater room acoustic people will use foam padding in the walls, or some other kinds of heavy and soft materials that act as strong insulators and absorbers of sound. They will also make use of special acoustic tape; although if the dimensions of the room are bad acoustic tape may be unlikely to help.

In the most extreme situations where there are problems with room acoustics and no amount of baffling or added insulating materials will help, sometimes it is useful to change the dimensions of a room by expanding the walls or starting over and building from scratch. Before going to such lengths in pursuit of superior room acoustics, however, one must try to exhaust all of the other options with freestanding sound baffles, sound proofing tiles on the walls, sonic noise reduction tape and so on to get great room acoustics with the least amount of effort.
