A Comparative Analysis of Transmission Loss in Helmholtz Resonators and Quarter Wave Resonators
This study involves a comparative analysis focusing on the transmission loss (TL) exhibited by both the Helmholtz resonator (HR) and the quarter-wavelength resonator (QWR). These resonators are designed to attenuate sound energy specifically at their respective resonance frequencies. ... Per saperne di più
Acoustic superscatterers for passive noise control
This poster presents a passive noise control of sound emananted from a vibrating cylinder using acoustic superscatterers. Acoustic superscatterer is a type of metamaterial whose scattering cross-section is larger than its real size. Numerical studies are conducted using pressure ... Per saperne di più

Beams-driven structures for piezoelectric energy harvesting/sensor and piezoelectric actuator
Beams-driven structures are structures that use beams to support their weight. The beams are typically arranged in a way that distributes the weight of the structure evenly. Beams-driven structures are often used in buildings, bridges, and other complicated structures. Beams-driven ... Per saperne di più
Studies on the effects of interfering structural vibrations on underwater Acoustic Vector Sensor
In this paper, we report FEM studies of the effect of unwanted interfering structural vibrations on the performance of an underwater Acoustic Vector Sensor (AVS) performed in the COMSOL Multiphysics simulation tool. An AVS is a compact sensor that measures a four-dimensional vector ... Per saperne di più
