This paper is concentrated for evaluating the sound quality of exhaust noise in the exhaust system design and development process. The present study shows the feasibility of using non-conventional noise cancellation technique. The effectiveness of such a technique is investigated using Ricardo WAVE, a computational engine simulation technique that uses a one-dimensional finite-difference formulation. The graphical interpretation using octave frequency spectra and 3-D colour maps of both an unmodified and a bridged engine are presented for both steady state and transient engine cases. A sound quality analysis is also presented using the psychoacoustic metrics of Loudness, Fluctuation, Strength and Boom. The main aim of this paper is to use of 1-D tool to simulate sound quality performance. Both cases like steady state and transient state conditions are simulated to evaluate vehicle sound quality with changing the exhaust configuration.
