Heat Pumps are a key technology for achieving energy efficiency and climate protection targets. However, their growing use in densely populated residential areas introduces new challenges, particularly regarding low-frequency noise emissions. Recent findings from the German Environment Agency (UBA) reveal that continuous low-frequency noise, such as that produced by Heat Pumps, can cause sleep disturbances, cardiovascular strain, and long-term health issues, even at relatively low sound pressure levels. These insights emphasize the need to address noise and vibration emissions early in the design phase of modern Heat Pump systems.

At the heart of these emissions lies a mechanical root cause: vibrations generated primarily by the compressor are transmitted to the unit’s h ...
