Issues with fan noise
Fan noise can often be due to resonance in the walls or poor acoustics in the room. Room layout and materials on the floor, ceiling, and walls have a significant impact on perceived noise. Poor acoustics can cause considerable noise problems.
Difference between dB ratings on the energy label and in the manual
- Sound pressure (dB data in the manual) refers to the perceived sound 3 meters from the unit. The sound level will change when closer or further away.
- Sound power (dB data on the energy label) is the sound energy emitted from the unit.
The measurements were taken according to European standards (UNI EN ISO3741:2010, UNI EN ISO10140-2:2010) at accredited test institutes.
A different noise level is measured in the room than stated in the manual
The measurements in manuals and product sheets are performed under specific European standards (EN standards) at accredited test institutes. Measurements in an ordinary room, such as a home, cannot be compared to these standardized tests.
