Minimize Vibrations, Reduce Noise, Design Quiet Heat Pumps
The heat pump market is evolving, with modern systems increasingly using two-stage vibration decoupling based on polyurethane (PUR). This approach improves performance by isolating vibrations, reducing noise, and enhancing overall comfort.

Session description
The increasing use of heat pumps is accompanied by rising expectations regarding acoustic performance. Low-frequency noise from compressors remains a key challenge, as it impacts both user comfort and regulatory compliance. A large share of this noise originates from structural vibrations transmitted and radiated as airborne sound.
This presentation explains the fundamental relationship between vibration and noise and outlines a structured approach to vibration isolation. Key factors such as static stiffness, dynamic stiffness, damping behaviour, frequency ratios, and the avoidance of resonance effects are addressed.
Different isolation concepts are compared to highlight their impact on acoustic performan ...
