Vibro-acoustic behavior of a multilayered viscoelastic sandwich plate under a thermal environment:
TL;DR: In this paper, the authors present numerical simulation studies on the vibration and acoustic response characteristics of a multilayered viscoelastic sandwich plate in a thermal environment, where the critical buckling temperature and vibration response were obtained using finite element method while sound radiation characteristics are obtained using boundary element method.
Journal ArticleDOI
Optimal design of modal beamformers for circular arrays
TL;DR: It is found that the well-known phase-mode beamformer for circular arrays can be viewed as an ideal minimum variance distortionless response beamformer against the planarly isotropic noise in the circular harmonics domain.

Identification of source velocities on 3D structures in non-anechoic environments: Theoretical background and experimental validation of the inverse patch transfer functions method
TL;DR: In this article, an alternative method known as inverse patch transfer functions, designed to identify source velocities and developed in the framework of the European SILENCE project, is presented. And the results (numerical and experimental) for a source with simple geometry (two baffled pistons driven in antiphase) are presented and discussed.

Microphone Arrays and Sound Field Decomposition for Dynamic Binaural Recording
TL;DR: In this article, the Directional Acoustic Properties of Rooms (ASAR) of rooms were analyzed and synthesized using the ASAR model. But the results were limited to rooms.

Annular acoustic black holes to reduce sound radiation from cylindrical shells
TL;DR: In this article, a semi-analytical method is proposed to determine the acoustic power, radiation efficiency, source location and far-field acoustic pressure of annular acoustic black holes (ABHs) shells and compare them with those of uniform thickness shells.
