Increasingly, vehicle engineers of all backgrounds are being taxed with restrictions on time, equipment and facilities due to competitive demands for cost and lead-time reductions. This has precipitated an industry-wide interest in processes which address these restrictions and allow engineers to “do more with less.” Vehicle sound system development is just one example of a standard, necessary phase of premium vehicle design subject to continuous cutbacks. This complex, time-consuming effort spans a variety of disciplines such as transducer design, psychoacoustics and digital filters. However, the most significant contribution to the overall performance exists in the tuning of such system parameters as equalization, crossovers, gain staging, time-alignment, and other vehicle-specific audio parameters.
