Acoustic Considerations - Krix MX-10 Installation Manual

The acoustics of the room have a major
influence on the overall performance of any
audio system in a home cinema installation.
Reflections off walls and ceilings, slap echo
and uncontrollable bass can all be detrimental
to the overall clarity and intelligibility of
the audio system and therefore the overall
enjoyment for the listeners.
A room with mostly hard surfaces and glass
can sound too "lively" with a reverberation
time which is often excessively long. In such
environments, the dialogue and soundtrack
in general can lack definition and clarity.
Conversely, a room which has an excess of
heavy acoustic treatment around every wall
can sound flat and unnaturally dead.

ACOUSTIC CONSIDERATIONS

The ideal scenario is to create a balance
between absorption
adding sufficient soft material to reduce the
reverberation time of the space. Untreated,
hard surfaces adjacent to the loudspeakers
are not ideal. Placing bass traps in appropriate
positions within the home cinema can help
to moderate bass response variations and will
result in a more defined bass that is realistic,
particularly when listening to sound effects
like gun shots or explosions.
It is highly recommended when designing
a dedicated home cinema that you consult
with an acoustic engineer to assist with the
acoustic treatment of the space.
manufacturers of acoustic treatments offer a
design service when using their products. A
and diffusion by detailed plan of the room with all dimensions
is required, which should also include the
seating layout and speaker positions.
Below is a link to an article written by acoustic
engineer Andrew Steel, with some hints on
acoustically treating a home cinema room
and some general tips for room isolation.
Note:- Sound proofing or isolation is very
different to acoustically treating a room. It is
a common mistake to concentrate on room
isolation and not consider room acoustics.
