11. SOUND DATA
The noise level of units is basically due to the fan rotation speed.
Obviously, with the same air flow rate, the fan speed will be lower if the required static pressure is low, while it will be higher (and
therefore noisier) if the required static pressure is higher.
11.1 Noise levels
The table below shows the sound levels of the units at the nominal working conditions:

Lw: sound power level calculated in accordance with EN 3744
Lp: sound pressure level measured in free field at 1 m from the unit, directionality factor Q=2, according to EN 3744 with ducted unit.
11.2 Sound attenuators reduction
The sound attenuators are of sound-absorbing baffles type. They are suitable for reducing the noise that propagates through the
ventilation systems in the aeraulic ducts.
To check the sound absorpion data to the various octave band frequencies, please refer to the our selection
software.
The sound attenuators are supplied in a dedicated section external to the base unit, thus increasing the total length of the unit
(depth and height of the section remain the same as the base unit).
Below are the additional section lengths according to size and profile, to be taken into account when calculating the final
length of the unit.
