A look at absorption

“

When the sound from a loud speaker encounters the boundaries of a room, a very complex series of reflections occur. In an untreated room, it's very difficult to isolate the direct sound alone because these reflections interact with it and among themselves to produce a sort of acoustic distortion. The more acoustic distortion is generated, the harder it is for the listener to hear all of the detailed information the loudspeakers are capable of delivering. There are a number of methods to tame reflections, harness the room modes, and, therefore, lower the decay time, all of which will be needed in an ideal acoustic environment. Let's look at them. The key to taming reflections is to use different absorptive materials inside the room. It would be great if there was a single building material that could achieve absorption across the entire audio bandwidth, but unfortunately, that material doesn't exist. Every material has its own absorption response, with most materials being very good at…
