Abstract
Noise in car cabins is a key aspect of the drivers/passengers’ comfort experience. It is produced by the aerodynamic interactions of the vehicle and the rolling, by the engine and all the auxiliary systems installed in the engine compartment. Although cars manufacturers focused their efforts to reduce the noise transmission inside the cabin, for Internal Combustion Engine vehicles (ICEVs) the mainly noise source is still the engine noise. Nevertheless, with the advent of hybrid/full electric vehicles (HEVs) in the automotive industry, the engine noise has been reduced dramatically, especially at low rpm, leaving emerging the noise of auxiliary sources. One of them is the air conditioning noise.
Although doesn’t exist a consolidated model to describe HVAC noise perception inside the vehicles, the paper intends to explore the expected changes of the drivers/passengers’ auditory perception from ICEVs to HEVs. The acoustic and psychoacoustic metrics of different binaural recordings, carried out inside ICEVs and HEVs, are showed and compared.
