1.
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.
2.
In acoustics, the logarithm of the ratio of a quantity to a reference quantity of the same kind is called a level. The base of the
logarithm (always ten, unless otherwise specified), the reference quantity, and the kind of level shall be specified. bel is a unit
of level when the base of the logarithm is ten, and the quantities concerned are proportional to power.
3.
Power consumption and heat output vary depending on the number and type of optional features installed and the
power-management optional features in use.
