Checking the sound quality of a car audio system at the end of the production line is required to satisfy rising customer expectations. Although transducers are pre-tested defects may be caused by improper handling during mounting. These defects, such as loose panels have a high impact on sound quality, are clearly audible but difficult to detect. In this paper a method is presented combining highly sensitive defect detection, root cause analysis for failed tests and assistance for meaningful limit definition.
