Octave band center frequency (Hz)

Notes:

1 Data is valid at free field condition (measured in a semi-anachoic room)

2 dBA = 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.
