Abstract

The study of percussion instruments is a wide section of musical instrument acoustics. Some percussion instruments exhibit harmonic frequency characteristics, while others not. The present work focuses on cymbals, which show nonlinear vibrational characteristics, providing an extra specificity. We apply a new methodology, combining experiments and finite element simulations, for the study of the acoustomechanical vibrational characteristics of a bell-shaped, alloy cymbal. The frequency response is obtained using the roving hammer technique and the modal analysis Electronic Speckle Pattern Interferometry is also employed, which enables the visualisation of the vibration modes. A finite element model is developed utilizing computational aided parametric design analysis and the simulation results are compared to the experimental modal results. This combination allows the detailed investigation of the instrument’s acoustodynamics, enabling the development of accurate simulation results, capable of providing inputs for machine learning models via further transient finite/boundary element simulations.
