Acoustical noise-emission values
Ÿ
Average sound-pressure levels:
– At operator position:
- Idle: PC 300PL - 34 dBA
PC 300GL - 35 dBA
- Operating: PC 300PL - 41 dBA
PC 300GL - 42 dBA
– At bystander position–1 meter (3.3 ft):
- Idle: PC 300PL - 29 dBA
PC 300GL 31 dBA
- Operating: PC 300PL - 34 dBA
PC 300GL - 36 dBA
Ÿ
Declared (upper limit) sound power levels:
– Idle: PC 300PL - 4.5 bels
PC 300GL - 4.7 bels
– Operating: PC 300PL - 5.0 bels
PC 300GL - 5.1 bels
Note: These levels were measured in
controlled acoustical environments according
to 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 your 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.
