The sound data have been compiled by means of sound
measurements methods as follows:
Pressure and drop: SS-ISO 5801.
Determination of acoustic sound level in duct:
SS-EN ISO 5136.
Determination of acoustic sound level in reverberation
room: SS-EN ISO 3741.

LwATot : Total A-weighted sound power level dB(A)
(ref 10 -12 W) = the sum of the sound power level in the
octave ranges.
LwA : A-weighted sound power level in octave range
dB(A)(ref 10 -12 W).
LpA : A-weighted sound pressure level in dB(A) accor-
ding to normed A-weightening correction and relating
to an effective absorption area of 20 m
2 with half sphe-
rical translation at a distance of 3 metres.
