7 - 2 VKM-GAV1
7 - 2 - 6 Sound data
7 - 2 - 6 - 1 Sound pressure spectrum
VKM50GAV1
Approximate
threshold hearing
for continuous
noise
Octave band center frequency (Hz)
NOTES
1 Over All (dB):
(B, G, N is already rectified)
2 Operating conditons:
• Power source: Single phase 50Hz 220V
• Model: VKM50GAV1
• Ventilation mode: total heat exhange
3 Measuring place:
Remark:
• Operation noise is measured in an anechoic chamber.
• The operation noise level becomes greater than this value depending on the operation
conditions, reflected sound, and peripheral noise.
• Operation noise differs with operation and ambient conditions.
• U-H: ultra-high, H: high, L: low
4 Location of microphone
1.5m
Measuring point
5 Operation noise differs with operation and ambient conditions.
