| Abstract: | The awareness of low-frequency noise generated by HVAC systems has been a serious and increasing problem. This paper will introduce the low-frequency noise sources in HVAC systems. The effect of low-frequency noise caused by HVAC systems is also included in this paper. C-weighted criteria should be adopted in the estimate of the low-frequency noise. Active noise control is a effective solution to low-frequency noise problems. |
