4. Optimum performance in reducing heat pump noise would be using a high STC (sound transmission classification, the higher the number, the better) “barrier” which has the highest possible NRC to reduce all reflections of the boxed-in area. Keep in mind that an adequate amount of airflow ...
The article reports on the decision that an air source heat pump at a house in Devon, England caused noise disturbance to neighbours. The noise of the pump was assessed and identified distinct and elevated low-frequency noise levels ...
When the heat pump unit is running, its steel structure will have a slight vibration, and this vibration will produce noise; the other is generated by the compressor and the exhaust fan of the heat pump unit. The latter may be the main part of the noise of the heat pump unit. ...
