Abstract: This study examines the sound emission and propagation of heat pumps, a key aspect for their acceptance in residential areas. Within the MENESA project, the focus is on validating a digital simulation model using SoundPLAN, incorporating ground factors and directivity effects. Acoustic parameters of a heat pump were measured in testing chambers at the Fraunhofer IBP, followed by noise propagation analysis in a real environment in Holzkirchen. The results indicate that the sound propagation in the digital model closely approximates reality. This validation allows for the digital placement of heat pumps in future steps to develop effective sound reduction measures. The analysis included assessments of noise emissions under various operational states to identify worst-case scenarios. Insights gained from this research can guide manufacturers and urban planners in implementing heat pumps more effectively, thereby facilitating the transition to climate-neutral heating solutions while addressing noise concerns for nearby residents.Keywords: Heat pumps, sound emission, noise simulation, urban planning.
