NOISE LEVELS
Base setting up AB
The noise levels refer to units operating in the nominal conditions (A35W7), due to a change of
external air temperature noise levels may change to ensure proper functioning of the unit within
operating range.
The acoustic pressure levels are calculated 1/ 5 / 10 meters away from the outer surface of the unit
operating in the free field and resting on a reflecting surface (directional factor of 2).
SWL = Sound power levels, with reference to 1x10
-12
W.
The Total sound power level in dB(A) measured in compliance with ISO 9614 standards, is certified
according to the Eurovent certification program.
Eurovent certification (E) exclusively refers to the Total Sound Power in db(A), which is therefore the
only binding acoustic specification (the values of the Octave bands in the table are indicative).
SPL = Sound pressure levels, with reference to 2x10
-5
Pa.
The sound pressure levels are values calculated by applying the ISO-3744 relation (Eurovent 8/1).
Low noise setting up AS
Extra low noise setting up AX
(E):
Data declared according to
EUROVENT LCP
certification programme. The values are for units without options and accessories.
