8.6 A Listening Room Example
In order to make these points more clear, an example of a room layout is
given in Figure 8.9, illustrating the principles we have given.
Figure 8.9 - Example listening room. The area around the speakers is
free of objects that would produce early reflections. A tapestry is
hung opposite the draperies to absorb the reflection from the side-wall
and to help maintain left-right symmetry. The area behind the listening
position contains items which help break-up standing waves and
flutter echoes. Heavily upholstered sofas will help avoid low-frequency
standing waves, while a carpet absorbs early reflections from the floor.
