Sound Pressure Spectrum - Daikin VRV III Technical Data Manual

10 Sound data

10 - 2 Sound Pressure Spectrum

REYAQ10P
Approximate
threshold hearing
for continuous
noise
NOTES
1 Over All (dB):
(B,G,N is already rectifi ed)
2 Operating conditions:
Power source: 380-415V 50Hz
3 Measuring place: Anechoic chamber (conversion value)
4 The operating sound is measured in anechoic chamber,
if it is measured under the actual installation conditions,
it is normally over the set value due to enviromental noise and sound refl ection.
5 Location of microphone.
