SUBJECTIVE IMPRESSION TO OBJECTIVE PRODUCT NOISE TESTING

摘要

In addition to detecting product faults that could cause premature failure, noise and vibration production testing can also be used to detect more subtle subjective noise problems that can cause warrantee claims. This paper uses case studies from the automotive, electronic and other industries to illustrate the process involved in creating objective production line tests that accurately predict subjective, qualitative customer judgements. It also includes practical, automated implementation of the results in the production environment using a PC based test system at a fraction of the cost of conventional systems.
