9 Sound data
4D052713A
Octave band sound pressure level dB(0dB=0.0002μ bar)
Octave band center frequency (Hz)
ERQ100AV1
Overall (dB)
Scale A 50.0
Scale C 62.0
(B,G,N is already rectified)
Measure in anechoic room
Note: 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
reflection.
