Abstract

A conformal scanning laser vibrometer was used to determine the vibrational modes of a 17-note portion of a C-lead tenor steelpan. The data represents the surface-normal motion of the instrument in response to an impulsive excitation intended to mimic the strike of a mallet. A description of this novel measurement system is presented, followed by the surface velocity data and a summary of response shapes and the frequencies at which those responses occur. The data indicate that individual note areas respond when adjacent or non-adjacent notes are struck, and clearly illustrate the complex vibration of the steelpan and the coupling between notes that produce the rich distinctive nature of the steelpan sound.
