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.
D E S I G N A T I O N S
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.
