Experimental evaluation of vehicle cabin noise using subjective and objective psychoacoustic analysis techniques
Abstract
Given the automotive industry's awareness of the importance of the perception of noise, vibration and harshness (NVH) emissions, there is an increased focus on the sound quality of automotive vehicle cabin noise. Psychoacoustic analysis using acoustic pressure measurements taken inside the vehicle cabin was performed. Suspension vibration measurements from several structural positions were also taken to evaluate vibration excitations. The goal was to be able to predict the psychoacoustic impact at the driver's ear position using the suspension vibration data measured outside the vehicle. Using the vibration data, it was possible to evaluate the transfer path of the excitation energy into the vehicle cabin. Using this, a correlation between the predicted in-cabin psychoacoustic results using the outside vibration measurement data and the direct psychoacoustic calculations from the in-cabin noise measurements was proven possible with some inherent limitations.
