Abstract
Several structural radiators have been well studied in the past century and are commonly used to illustrate principles of structural-borne acoustic radiation. These structural radiators include the membrane, thin beam and thin plate. The principles of vibration and acoustic radiation of these radiators will be overviewed in terms of their normal modes. The standard assumptions which allow these structures to be useful in illustrating general principles of structural acoustics will also be outlined. The relationship of common percussion instruments to these structural radiators will then be presented with emphasis on which of the previously discussed assumptions hold for each instrument and which assumptions do not. Modern methods for studying the vibration and acoustic radiation of these instruments will then be outlined.
