Description of how the room or space affects the quality of sound produced through an audio system or live audio performance. While room interaction is primarily used in audio/video to describe how the room affects sound played over an audio system, it is also important in live audio venues. oom interaction describes the acoustics of the room or how the space interacts with sound waves. All spaces interact with sound in some way (with the exception of anechoic chambers, which are designed specifically to eliminate all room interactions in order to test audio equipment). Walls, floors and ceilings reflect sound and send sound waves back into the room. These sound waves may reinforce each other or cancel each other out depending on how they hit. When a wave trough meets a wave peak they will cancel out so no sound is given while two wave peaks meeting will increase the sound pressure or volume of that specific frequency). oom interaction colors the sound and distorts it making the recreation imperfect for the listener. Hard surfaces such as wood floors and tile walls increase reflections and make for a more “live” room or a room with lots of interaction and reverberation. Soft surfaces such as carpet, rugs and furniture absorb sound making the room less alive and decreasing room interactions. ecause of the way a room interacts with speakers, speaker placement is critical. By moving a speaker a few inches or angling it a few degrees, room interactions may be altered with the effect of improving or degrading sound quality. A particularly potent and noticeable problem is with how low bass frequencies interact with the room creating extremely loud boomy and muddy sounds at some frequencies (when sound waves reinforce one another by combining peaks). enerally, a space with less interaction is preferable to one with more interaction. There are many products on the market devised to capture sound waves and “tune” a room by decreasing room interactions. The most important means of taming room interactions is proper speaker placement. Secondly, room interactions can be aided by making changes to the space such as adding a rug to a wood floor or an overstuffed chair or a bookcase (the bookcase interferes with simple sound wave reflection by creating a multi-faceted surface which sends sounds waves in many directions and thus lessens the possibility of sound waves interacting). Other methods, such as using an equalizer to adjust the frequency response for the room, are also available and can be very effective when properly used. In any case, the room is as important to how your music sounds as the speakers or other electronics used to produce the sound waves and thus room interactions must be noted and taken into account to achieve the ultimate sound quality.
