10.6 A Listening Room Example
In order to make these points more clear, an example of a room layout is
given in Figure 9.6, illustrating the principles we have given.
Figure 9.6 - Example listening room. The area around the speakers is free of
any object 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. Tube traps are placed in the corners,
centered at the wall behind the speakers, and centered at the wall behind the
listener.
