Acoustical noise-emission values
Average sound-pressure levels:
At operator position: Idle: 38 dBA Operating: 43 dBA
At bystander position–1 meter (3.3 ft.): Idle: 33 dBA Operating: 37 dBA
Declared (upper limit) sound power levels: Idle: 4.8 bels Operating: 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
