An Experimental Approach to Vibro-Acoustic Study of Beam-Type Structures
- Jeniffer Torres-Romero, William Cardenas, J. Carbajo, E. G. S. Eulogio, Jaime Ramis-Soriano
- Physics
- 11 May 2018
In this paper an alternative procedure to vibro-acoustics study of beam-type structures is presented. With this procedure, it is possible to determine the resonant modes, the bending wave propagation…

Optimal Material Parameter Estimation by Fitting Finite Element Simulations to Loudspeaker Measurements
- William Cardenas, W. Klippel
- Physics
- 14 May 2018
Important characteristics for the sound quality of loudspeakers like frequency response and directivity are determined by the size, geometry and material parameters of the components interfacing the…

Viscoelastic Response of Graphene Oxide‐Based Membranes and Efficient Broadband Sound Transduction
- Kaiwen Hu, William Cardenas, T. Szkopek
- Engineering, PhysicsAdvanced Functional Materials
- 11 November 2021
Freestanding micrometer thick graphene oxide (GO) membranes combine high stiffness, low mass density, and high loss coefficient. This unique combination of properties is ideal for efficient and…
Active Vibration Control of Breakup Modes in Loudspeaker Diaphragms
- William Cardenas
- Physics
- 11 May 2017
One of the factors which contribute to the degradation of the sound quality of the loudspeakers are the breakup modes of the membrane since they cause complex directivity patterns, peaks and deeps in…
