5. Acoustic characteristic curves

TCGB0075 rev.0 - 11/2012

5.1 Sound pressure level for outdoor unit

5.1.1 Considerations

Distance of the unit from the measuring point: At 1 meter from the unit’s front surface; 1,5 meter from floor level.

The data is measured in an anechoic chamber, so reflected sound should be taken into consideration when installing

the unit.

The sound measured with the curve A shown in dB(A) represents the attenuation in function of frequency as perceived
by the human ear.

Reference acoustic pressure 0dB=20μPa
