– There are several facets of room acoustics measurements, but the most commonly used method is to measure the uniformity of the sound.

– This approach uses a random noise signal (played out through your system) that is then measured using instrumentation-grade microphones placed in designated areas of your listening room.

– The result is that the frequency response of your listening room can be displayed and based on that, changes in the room’s equalization can be made.

– This allows you to see the effects of things like furnishings (drapes open / closed, doors open / closed etc)
