Soundcheck for heatpumps: Psychoacoustics for minimum noise generation

Air/water heatpumps with heat outputs from 3 to 30 kW enjoy a high level of acceptance in heating technology. However, they do not work completely silently and the more dense the buildings are, the more the neighbors can get disturbed by noise pollution. It is by no means just the measurable sound pressure level that is crucial, but human noise perception, which is where psychoacoustics and its examination methods come into play.»
