Sound data

8 - 1 Sound pressure spectrum

EBHQ011-016AA6W1
E(D/B)(H/L)Q011*
HEATING
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.
