By estimating the sound field characteristics of an automotive cabin at a period prior to the actual manufacture of a car using available information on interior size, shape and acoustic materials, it is possible to realize a car audio system of high quality through appropriate placement of loundspeakers and determination of best electrical compensation networks, among others.We have established a computer-aided method based on the sound ray-tracing method and digital signal processing techniques usually applied to the analysis of large concert hall acoustics, which simulates the transmission characteristics between a loundspeaker and a listening position.
