5.1 Sound pressure level for outdoor unit
5.1.1 Considerations
1
Distance of the unit from the measuring point: At 1 meter from the unit’s front surface; 1,5 meter from floor level.
2
The data is measured in an anechoic chamber, so reflected sound should be taken into consideration when installing
the unit.
3
The sound measured with the curve A shown in dB(A) represents the attenuation in function of frequency as perceived
by the human ear.
