Several factors can degrade the sound from even
the best loudspeakers in a listening room. One
of the most important is the interaction of sound
from the loudspeakers with large surfaces such as
walls, the fl oor and the ceiling in the room. Even
with careful loudspeaker placement and acoustical
treatments, there are signifi cant problems that are
caused by room acoustics. These include refl ections
from nearby surfaces and standing waves created
between large parallel surfaces in the room. In a
home theater, the situation is further complicated
because there are several listening locations. The
effects of room acoustics on the sound arriving at
each person’s ears are very different and the result is
a listening experience that is degraded in a different
way for each person in the room.
It is not uncommon to have variations in two adjacent
seats as large as 10 dB, particularly in the frequency
range below 250 Hz. The solution to this problem is to
apply room correction after measuring precisely how
each loudspeaker interacts with the room. Because
the room causes variations in the frequency response
of the loudspeakers that are so large from seat to
seat, it is important to sample the sound from several
locations in the listening room. This should be done
even if there is only one listener. Measurement at a
single location is not representative of the acoustical
problems in the room and will, in most cases,
degrade overall performance. Audyssey MultEQ is
the only technology able to achieve room correction
for multiple listeners in a large listening area. It does
so by combining the data collected at several points
in the room from each loudspeaker and then applying
correction to minimize the acoustical effects of the
room and match the frequency resolution of human
perception (known as psychoacoustics).
Further, MultEQ correction is applied in frequency
and time domains and removes artifacts, such as
smearing or modal ringing, sometimes associated
with traditional methods of room equalization.
In addition to correcting frequency response problems
over a wide listening area, Audyssey MultEQ provides
a completely automated sound system set-up
process. It identifi es the number of loudspeakers
connected to the amplifi ers and whether they are
satellites or subwoofers. If there is a least one
subwoofer connected, Audyssey MultEQ determines
the optimum crossover frequency between each
satellite and the subwoofer(s). It automatically
checks the polarity of each loudspeaker and alerts
the user to the ones wired out-of- phase relative to
the others.
It measures the distance to each loudspeaker from
the main listening position and adjusts the delays
so the sound from each loudspeaker arrives at the
same time. Finally, Audyssey MultEQ determines the
playback level of each loudspeaker and adjusts the
volume trims so all levels are equal.
