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.

Method and apparatus for objective measurement of noise

An environmental test facility for testing vehicle suspension and body components is disclosed. The test facility is transportable over conventional roads and is essentially self-contained for set-up at manufacturing facilities or other locations to facilitate testing of vehicles. A four-poster hydraulic suspension test simulator is provided. A temperature-controlled environment and simulated sunlight sources may also be provided.
