9 Sound data
9 - 1 Sound pressure spectrum
3TW57537-1
Sound pressure level (dB)
Octave band center frequency (Hz)
EWAQ005AC
EWYQ005AC (Cooling)
NOTES
1 Data is valid at free field condition (measured in a
semi-anachoic room)
2 dB(A) = 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.
