Assessment of automobile radio system performance in noisy EM environments

A procedure is presented to simulate the complete automobile radio system, from antenna to speaker. The method involves generating reduced order models of all relevant components and interactions, which are then linked together in a time-domain system solver. To illustrate the usefulness of this simulation capability in vehicle-level system design a novel algorithm for automated computer rating of automobile audio tracks is developed. The algorithm uses wavelet and Fourier decompositions for automated computer rating of audio quality. The algorithm developed is validated by comparing its output to a study using human subjects to score recorded audio tracks
