Evaluation of Noise Level Inside Cab of a Bi-Fuel Passenger Vehicle
Authors: , , ,
Abstract: It is well known that the vehicle interior noise comfort is one of the main target which may attract customers for purchasing a vehicle. Eventually, the amount of discomfort depends on magnitude, frequency, direction and, as well as, on the duration in vibration exposition inside the cabin. The comfort of the driving strongly influences the driving performances. Generally, the acoustic noise exposition depends on two main sources: engine and powertrain systems and interaction between tyre and road surface. In this paper, the sound quality assessment of a bi-fuel passenger car tested over a chassis-dynamometer bench at different vehicle operating conditions, will be analyzed. The main target of the study is to measure the perceived noise inside cabin for different vehicle speed conditions assessing the influence of the investigated operating conditions on the driver’s acoustic comfort.
