Sound source localization based quality monitoring

The importance of product quality control cannot be overestimated, and effective quality control starts from the definition of appropriate key performance indicators for a product. In many cases, acoustic noise creates a critical quality problem, for example, annoying squeak and rattle sound from a car door can cause a significant warranty failure. In this research, we are developing a noise detection and localization method in a clamorous manufacturing environment. Sound source localization and noise cancelling methods are employed to identify the precise location of noise source.
