Heat pumps are an efficient and environmentally friendly way to heat and cool your home. However, as with all technical devices, a heat pump can also generate noise. This noise can be annoying for you and your neighbors. 

In this article you will learn: 

• What are the noise limits for heat pumps?
• How to calculate the sound level of your heat pump
• What measures you can take to improve sound insulation
• How urbanshell soundproofing hoods can help you

Limit values ​​for the noise of heat pumps 

The permissible noise pollution from heat pumps is regulated in DIN 4109 “Sound insulation in building construction”. The standard distinguishes between three types of noise: 

• Noise level: This value describes the A-weighted continuous sound level of the heat pump. The permissible noise level is 50 dB(A) during the day and 35 dB(A) at night.
• Peak level: This value describes the highest A-weighted sound pressure level generated by the heat pump. The permissible peak level is 65 dB(A) during the day and 45 dB(A) at night.
• Impulse level: This value describes the A-weighted sound pressure level of short, sudden noises. The permissible impulse level is 70 dB(A) during the day and 50 dB(A) at night.

Calculating the sound level 

The noise level of a heat pump depends on various factors, such as the type of heat pump, the output, the distance to the building and the surrounding buildings. 

To calculate the sound level of your heat pump, you can use the following formula: 

Sound level = Lw + Kp – A + 10 log(D/D0) 

• Lw: Sound power level of the heat pump (in dB(A))
• Kp: Correction factor for surrounding buildings (in dB(A))
• A: Air absorption coefficient (in dB(A)/m)
• D: Distance between heat pump and emission point (in m)
• D0: Reference distance (1 m)

Soundproofing measures 

There are several measures you can take to improve the sound insulation of your heat pump: 

• Choosing a quiet heat pump: When purchasing a heat pump, pay attention to the sound power level. The lower the sound power level, the quieter the heat pump is.
• Installation of the heat pump: Install the heat pump so that the distance to the neighbors is as large as possible.
• Installation of a soundproof hood: A soundproof hood can reduce the noise level of the heat pump by up to 10 dB(A).
• Planting trees and shrubs: Trees and shrubs can also reduce noise levels.

Soundproof hoods from urbanshell

The soundproofing covers from urbanshell offer an effective way to reduce the noise from your heat pump. The covers are made of high-quality materials and are characterized by their durability and weather resistance. 

The advantages of urbanshell soundproof hoods: 

• Effective noise reduction: Reduce the noise level of your heat pump by up to 6.6 dB(A).
• High quality: The hoods are made of high-quality materials and are characterized by durability and weather resistance.
