Occupants of buildings located in areas of high-level impulse noise usually report that the main annoyance factor is the rattle produced by house components upon vibration. This type of noise is associated with helicopter flybys and blast overpressure from artillery and other military training operations. Methods are needed for mitigating rattles in both existing structures and future construction. This report analyzes several different elements to identify individual components contributing to rattle. Elements studied include windows, doors wall mounted objects, bric-a-brac, ductwork, gutters, and light fixtures, among others. In general, the primary source of rattle is any small gap between two hard surfaces that are subject to vibration from an exterior noise source. Upon excitation, these surfaces can impact each other, producing the sound. Other rattle sources are identified and methods are recommended for eliminating or reducing noise from the individual elements. Keywords Impulse noise, Buildings, Vibration.
