2. The noise emission level stated is the declared (upper limit) sound
power level, in bels, for a random sample of machines. All
measurements are made in accordance with ISO 7779 and reported in
conformance 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 noise emission level
stated in the declared (upper limit) sound-power level, in bels, for a
random sample of system.
