Influence of strain-gauge sensors on the vibrational behavior of single reeds

Experimental measurements are often used in conjunction with physical modeling to characterize sound generation in musical instruments. Focusing on single-reed woodwind instruments, such analyses have provided accurate descriptions of the coupling between the sound excitation mechanism and the resonator during steady-state regimes. For note transients however, more detailed measurements of the reed vibrations under real playing conditions are required. Therefore, strain gauge sensors haven been placed on a series of clarinet and saxophone reeds, in order to capture the vibrations without interfering with the player. Different ways of attaching the sensors to the reeds are considered and the resulting influence is quantified by means of Laser Doppler Vibrometry and Electronic Speckle Pattern Interferometry.
