“…A study in cymbals combining FEM modeling, measurements and holography was performed by Perrin et al [21]. In continuation of his work, Perrin discussed the nonconstant thickness of the cymbal considering varying thickness in the FEM simulations [22]. The variation in thickness and the curvature of the cymbals was the focus point of the detailed theoretical studies of Duccechi et al [11] and Nguyen et al [12]; however, the results were not validated by experimental measurements.…”

The present study encompasses a thorough analysis of the vibrations in a splash musical cymbal. The analysis is performed using a hybrid methodology that combines experimental measurements with parametric computer-aided design and finite element method simulations. Experimental measurements, including electronic speckle pattern interferometry, and impulse response measurements are conducted. The interferometric measurements are used as a reference for the evaluation of finite element method modal analysis results. The modal damping ratio is calculated via the impulse response measurements and is adopted by the corresponding simulations. Two different approximations are employed for the computer-aided design and finite element method models: one using three-point arcs and the other using lines to describe the non-smooth curvature introduced during manufacturing finishing procedures. The numerical models employing the latter approximation exhibit better agreement with experimental results. The numerical results demonstrate that the cymbal geometrical characteristics, such as the non-smooth curvature and thickness, greatly affect the vibrational behavior of the percussion instrument. These results are of valuable importance for the development of vibroacoustic numerical models that will accurately simulate the sound synthesis of cymbals.

“…The data validity from tone measurements of idiophones (particularly gongs) was questionable by Schneider (2001). Normal modes of a small gamelan gong using ESPI and finite element methods were done by Perrin et al (2014) and Herington et al (2010). Finite element analysis and gong acoustics were done by McLachlan (1997).…”

This study visualises the mode of the vibration of kulintangan using Electronic Speckle Pattern Interferometry (ESPI) to reveal the modes. It was found that the production of sound by the kulintangan was dominated by a particular mode which may be the (0,1), (1,1), (2,2), (3,2), and (4,2) of free edge circular gong. The spectrum distribution from the strike on the kulintangan showed it. The small gong A-H has an approximately harmonic spectrum with a fundamental frequency of 1240, 1055, 934, 792, 705, 624, 474, and 422 Hz. The gong does not display a similar occurrence of harmonics due to the ruggedness of the surface texture of the gong. This finding can be of great importance to facilitate a better understanding of the mechanisms involved in the sound production of musical instruments. Our research is visualising the sound sonically through PicoScope oscilloscopes and ESPI.

“…In an earlier study with the same gong 2 we produced an axially symmetric finite-element model (FEM) and compared its predictions with experimental results obtained using Electronic Speckle Pattern Interferometry (ESPI). We now report an extension of this study using Scanning Laser Doppler Vibrometry (SLDV) using a mounting method which better simulates that used in practice.…”
