Acoustic Noise Evaluation inside Vehicles under Different Traffic Conditions
Acoustic channel, vehicle noise, impulsive noise, regression analysis, MLE
This work aims to analyze the interior acoustic noise in a vehicle under several traffic conditions by comparing different statistical models used for evaluating noise impulsiveness. Initially, we present the importance of studying the sound quality for the development of multimedia and control applications and of smart vehicles. Next, we discuss previous works on the acoustic channel inside vehicles, as well as the approaches to statistically model this type of channel. The measurement setup we used and the analyses of the collected data are presented in order to highlight which measurements conditions contribute the most to the interior noise levels and to impulsivity.
