Detection and Evaluation of Annoying Sources Affecting Noise Quality in Car Passenger Compartment

In car marketability, noise quality inside the passenger compartment is assuming increasing importance.
This paper describes the main lines of general methodology aimed to the detection and quantitative evaluation of disturbing noise sources inside a car when no significant difference can be detected by means of traditional acoustic measurements.
An example of application of this methodology, for the particular case of noise known as "rumble", is also given, to illustrate how the complexity of the problem can be dealt with.
The methodology comprises both usual monaural measurements and binaural analyses, better suited to match with the human hearing mode, and with application of statistical modeling methods to correlate subjective aspects to objective physical "features" of sound events, selected by means of a "principal components analysis".
