+ | ===== Introduction ===== | ||
+ | |||
+ | When analysing potential sound paths, the cause of the noise, i.e. the excitation source, should always be considered first. At this point, sound proofing measures can be put into practice most effectively and with the least effort and are therefore preferable to secondary sound protection measures. In the case of heat pumps, the excitation sources are the compressor, the ventilators, | ||

+ | ===== Summary ===== | ||
+ | |||
+ | The analysis of the sound sources and the sound paths in compact heat pump units shows that it is the primary task of manufacturers to select low-noise ventilators and compressors. Furthermore, | ||
+ | Decoupling structure-borne sound is also of importance for the associated ductwork. The first sound absorber should be placed as near the unit as possible. Dimensioning of the sound absorber should not only ensure that the limit values for the A-rated overall sound level are adhered to, but should also analyse exceeding of the auditory threshold, particularly in the low-frequency range. Which limit values should be adhered to here is explained in more detail in the article relating to standards and regulations. | ||
