Abstract
A method of objectively and subjectively monitoring noise and correspondingly level or loudness thereof in a product or assembly. The method includes placing a product on the vibration generator. Activating the vibration generator to move or shake the product to simulate usage conditions. A sound recording instrument measures and records the noise emitted by the product or assembly. Comparing an objective metric computed from the recorded noise with a threshold metric. Evaluating the vehicle to determine the noise source when the objective metric exceeds the threshold metric. Saving the objective metric along with the information relating to the source of the noise and necessary repairs for further evaluation and statistical analysis.
