Computational modelling of acoustic scattering of a sound source in the vicinity of the ground [PDF]
, 2009 The paper presents a computational model for acoustic scattering of a near-the- ground sound source around a body moving in a uniform flow. Using the method of images and the concept of reflection coefficient, the half space Green's function in a ...

A Novel Algorithm for Directional Scattering in Acoustic Ray Tracers
Acoustics, 2023 It is vital to consider acoustic scattering when using geometrical acoustic simulation techniques, such as ray tracing. However, there are few methods for modelling scattering, and most rely on strong assumptions of uniformity on the distribution of ...

A numerical approach for acoustic radiation and scattering of moving bubbles at low frequencies
Frontiers in Physics, 2023 The acoustic radiation and scattering of underwater bubbles play an important role in ocean exploration, target localization, acoustic measurements, etc. The two-phase fluid flow and moving boundary result in the lack of means to predict the sound field,

Tunable acoustic scattering from a spatiotemporally modulated flat metasurface [PDF]
JASA Express LettersSpatiotemporal modulation (STM) has recently been used to improve diffusion from finite apertures of conventional acoustic diffuser profiles by introducing STM of the termination impedance of the diffuser wells and to scatter acoustic energy at ...

Volume oscillation and acoustical scattering of a gas bubble [PDF]
MATEC Web of Conferences, 2019 The exact solution of a gas bubble’ volume was obtained based on volume oscillation of a gas bubble. The volume pulsation, acoustic impedance, scattering pressure of a gas bubble, acoustical power of scattering and acoustical scattering cross section of ...
