Abstract
Abstract An acoustic rack for mounting electronic components and the like includes vertical, parallel spaced-apart rack rails positioned near the open front of a box-like rack case. Each rack rail has a front face parallel to the open front of the rack case and is provided with throughholes for mounting electronic component chassis thereon. The front face of each rail is further provided with a layer of resilient, insulative material which dampens and prevents transmission of vibration and impact shock imparted to the rack case to the electronic components mounted and further prevents transmission of electrostatic discharge and radio frequency interference and other electrical disturbances to and from the electronic components and the rack rails.
