NOTES
1 Data is valid at free field condition (measured in a
semi-anachoic room)
2 dB(A) = A-weighted sound power level (A-scale
according to IEC)
3 Reference acoustic pressure 0dB = 20μPa
4 If sound is measured under actual installation
conditions, the measured value will be higher due to
environmental noise and sound reflections.
