Enter here the position of your heat pump, the stated sound power of the pump and the distance you want to measure at.

Calculate in a few seconds how many decibels you can save in your specific situation with a Climeleon Wave unit cover. You then know fairly accurately how many decibels you can damp. The Climeleon Wave has been developed together with heat pump manufacturer Fujitsu General. The Decibel Calculator calculates the sound pressure according to the sound spectrum of these units.

Please note that this calculation is only valid with a minimum distance of 8m between the two buildings.

Select the height distance starting at the level of the unit.

You will find this on the unit in the manual or product folder.
Note: Do not enter the sound power but the sound pressure in decibels measured at 1m from the unit and at 1,5m from the ground. Entering sound power will provide an erroneous result.

The simplified calculation assumes standard damping and is purely indicative.
In many cases, the effective damping is higher.

To perform a detailed calculation, you must enter the sound power for all frequencies below.

A: The distance between the unit and the measurement point.

A: The distance between the roof edge and the measurement point.

H: The height at which you want to measure the sound, measured from the height level of the unit.

B: The distance between the unit and the outside wall is set at 5m by this tool. If the actual distance differs from this value, the result will be slightly off.

Result

At 1m from the unit, the sound pressure is 0. With the housing, this is reduced to 0.

Selection of Climeleon unit cover sitting on solid ground (gravel bed) without additional beams or vibration dampers.
Placement on a flat roof with additional beams or vibration dampers greatly increases the chance that you will need a larger type of Climeleon unit cover.

The damping result of the Climeleon Wave depends on the direction, i.e. the damping is not the same along all the sides.

The Decibel Calculator calculates the sound pressure from the side. The correction values for the other orientations are given here. For example, if you want to know the sound level along the front, you must add 2dB.
