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.
