Conference Paper
Audio System Variance in Production Vehicles
AES Conference: 48th International Conference: Automotive Audio · Paper 5-3 · September 2012
Abstract
Production vehicle audio systems are custom engineered to achieve acceptable performance levels for a given vehicle's market segment and the audio system's class based on brand, number of loudspeakers, amplifier, signal processing etc. But little attention has been paid to verifying the performance consistency across any specific production vehicle audio system type. On the other hand, mass produced loudspeakers are known to exhibit production deviations that affect sensitivity, bandwidth, frequency response and distortion characteristics. When utilized in production vehicle audio systems loudspeakers have production tolerances that compound the system level variance. In this paper audio systems in production vehicles are analyzed to quantify system performance variance.
