Abstract: Air conditioners installed on different buildings will show different noise problems. The operating frequency of the air conditioner, the vibration of the air conditioner, and the building resonance frequency have a greater impact on the low-frequency noise. In order to study its influence on low-frequency noise, install air conditioners in semi-anechoic rooms and design to simulate the phenomenon of low frequency sound generated by building structures, experimental research was carried out on it. Experimental study shows the influence of specific operating frequency of air conditioner on low-frequency noise of buildings. Aiming at the low frequency noise of buildings caused by the air conditioner, it is effectively solved by vibration isolation.

Key words: Air conditioning, Building, Low frequency noise
