Audio room or acoustic room commonly built to home entertainment, home theater, karaoke, etc. This is a room specially designed to absorb reflection sound out from home theater system, home entertainment system, karaoke set, game console, or hifi stereo system. As audio sound characteristic, it will reflect when strike against hard surface and absorbed when beat to soft and sponge surface.

What?s happen when audio sound reflected?

The room?s walls, floor, and ceiling reflect sound so that you hear it emanating not only from your speakers, but also from other parts of the room. These reflections can enrich the sound and make it fuller and more natural, but they can also distort sound by amplifying some frequencies while canceling others out altogether. This can lead to boom-sounding bass and harsh mid-range and high frequencies.

A room with parallel reflective surfaces?and that?s just about any room?will create a phenomenon known as standing waves. Standing waves are created when sound waves are reflected back and forth between two walls or between the floor and the ceiling. The sound waves travel across the room, bounce off the opposite wall, and encounter the identical sound waves emanating from the speakers, cancelling each other out. Standing waves distort bass and lower midrange frequencies.

One way to reduce the prevalence of standing waves is to eliminate parallel surfaces. If we didn?t want to slope the floor or ceiling, and we didn?t want to create a crooked wall (remember, this is a house), so we can created a room within a room. The room?s exterior shell is framed with 2×6 studs, but I had the carpenters nail down a second top and bottom plate about an inch away from the first with 2×4 studs to form an independent wall. This second wall is canted by about two degrees from the first, so that the room?s front and back walls are no longer parallel.

With this way our home entertainment, home theater, karaoke set, game console or hifi stereo set will sound out without reflection in audio room or acoustic room. That?s mean the sound out from our system without distort caused standing wave.
