These
levels
were
measured
in
controlled
acoustical
environments
according
to
the
procedures
specified
by
the
American
National
Standards
Institute
(ANSI)
S12.10
and
ISO
7779
and
are
reported
in
accordance
with
ISO
9296.
Actual
sound-pressure
levels
in
a
given
location
might
exceed
the
average
values
stated
because
of
room
reflections
and
other
nearby
noise
sources.
The
declared
sound-power
levels
indicate
an
upper
limit,
below
which
a
large
number
of
computers
will
operate.
