Abstract

The heating, ventilation and air-conditioning (HVAC) system is one of the most critical noise sources of the in-vehicle environment, especially when cars move at low speed or low engine rotation. With the transition to electric vehicles (EV) from internal combustion engine vehicles (ICEV), the contribution of powertrain becomes lower on the background noise inside car cabins. The authors have been conducting a collaborative research on HVAC sound quality inside car cabins. In this paper, the results of a subjective evaluation of HVAC sound quality were presented that attempted to compare the perceptual differences among the two groups, i.e., EVs and ICEVs. The result revealed the difference in the noise perception among the two types of vehicles, especially at softer airflow rate conditions.
