Sound data

7 - 1 Sound pressure spectrum

ERHQ011-016
2
7
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 pressure 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.
