Abstract:High levels of low frequency noise are created by aircraft during take-off and landing. A by-product of low frequency sound incident on a building façade is the excitation of structures within the building into vibrations. Such acoustically-induced structural vibrations may be imperceptible, but they may cause rattle. Rattle is caused by the intermittent loss of contact between two bodies due to vibration [1]. Rattle causes secondary noise emissions, which are often perceived as annoying [2]. Investigation of the mechanisms leading to rattle onset and the development of rattle mitigation strategies are needed to reduce rattle emissions, and the associated annoyance.
