3
The sound pressure level was calculated with an assumed room insulation of 8 dB(A). This corresponds to a dis-
tance of 2 m, a room volume of 100 m³ and a reverberation time of 0.5 s (in accordance with VDI 2081).
4
Sound pressure level < 20 dB (A) and sound power level < 28 dB (A) outside the usual measuring and audible
range.
