Development work for the reduction of vehicle noise Is mostly performed in laboratories. The paper describes testing equipment of the latest state of the art that is used in a laboratory for vehicle acoustics. The test specimen and testing equipment are installed in an acoustic chamber. All design measures for noise reduction will be described. The equipment for noise measurement and analysis is included in the chassis dynamometer control and automation system. Noises and vibrations are picked up by special measuring devices and analysed in a separate computer, which is linked to the test stand computer. The results of measurement will be presented and explained.
