Sound absorption mechanism of underwater anechoic coating with spherical cavities

Journal of Mechanics
Abstract An axisymmetric theoretical model is simplified to investigate sound absorption in the underwater anechoic coating with spherical cavities. An empirical equation is put forward to predict the frequency at the first absorption peak.

Thermal, Structural, and Molecular Characterization of a Model Cereal–Milk Infant Formula: Impact of Ultrasound Pre‐Treatment Prior to Spray Drying

Food Science &Nutrition, Volume 14, Issue 7, July 2026.
This study evaluated the efficacy of an ultrasound pre‐treatment applied to a complex cereal–milk infant formula prior to conventional spray drying to mitigate inherent stickiness and yield challenges. Acoustic cavitation (30–90 s) significantly reduced suspension viscosity and improved atomization efficiency, elevating powder recovery yield from 12 ...

The effects of sound propagation and avoidance behaviour on naval sonar levels received by cetaceans

, 2012
The use of active sonar is deemed to be essential for naval operations, but its potential impact on marine life has raised concerns worldwide. In a risk-assessment framework, characterisation of risk of harm is accomplished by combining exposure ...

Deep Segregation: Informality, Trust and the Making of Discrimination in Markets

Antipode, Volume 58, Issue 4, July 2026.
ABSTRACT This article advances the concept of deep segregation to theorise how social exclusion is produced through the everyday organisation of market access rather than through spatial separation alone. Deep segregation refers to a relational and processual form of segregation constituted through segmented routes of access, intermediary networks and ...

Locally resonant phononic woodpile: A wide band anomalous underwater acoustic absorbing material [PDF]

, 2009
To meet the demand of modern acoustic absorbing material for which acoustic absorbing frequency region can be readily tailored, we introduced woodpile structure into locally resonant phononic crystal (LRPC) and fabricated an underwater acoustic absorbing

A Sandwich Coating Containing Micro-perforated Panel for Underwater Sound Absorption

IOP Conference Series: Materials Science and Engineering, 2019
Abstract This paper focuses on the underwater application of Micro-perforated panel (MPP) for broadband sound absorption. In this paper, MPP-rubber coating (MPPRC), a novel sandwich anechoic coating embedded with MPP in high-viscosity condition, is proposed.
