9 Sound data

9 - 3 Sound Pressure Spectrum Quiet Mode

NOTES

1 Data is valid at free field condition (measured in a semi-anachoic room).

2 dBA = A-weighted sound pressure level. (A-scale according to IEC)

3 Reference acoustic pressure 0dB = 20Pa.

4 If the sound is measured under actual installation conditions, the measured value will be

higher due to environmental noise and sound reflections.

5 Data is valid at night quiet mode level 2

Measuring location (discharge side):

Sound pressure level (dB)
