ACOUSTICS STUDIES

The report documents the noise and vibration studies for the Bay Area Rapid Transit District System. Several of the studies involved the investigation of new concepts of noise and vibration control, such as the use of sound barrier walls (often called sound barriers or parapets) along the right-of-way, wheel damping, rail damping, and the use of rail fasteners incorporating vibration-reduction and noise-reduction features. Considerable effort was expended in determining the rank order of the various important sources of noise produced by steel-wheel vehicles passing over steel rails. (Author)
