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 both in existing structures and future construction. This report describes work on an experimental test facility being developed to study the impulse problem systematically and empirically. This facility simulates blast noise on a repeatable basis and allows alternative solutions to be evaluated. Initial data are evaluated to identify ways of improving the facility and test methods used. Keywords: Impulse noise, Buildings, Vibration, Test facilities.
