Viscoelastic and acoustic characterization of polyurethane‐based acoustic absorber panels for underwater applications

“…1,5 The sound waves in air or water are longitudinal waves, where the particle motion is parallel to the direction of sound propagation. [11][12][13] SOAB material developed by BF Goodrich consists of butyl rubber filled with aluminum. The role of inclusions in damping material can be explained by mode conversion mechanism, that is, mode conversion of longitudinal deformation to shear deformation is readily achieved at the boundaries of soft (air filled) cavity inclusions.…”

“…9,10 There are several absorber materials available commercially. [11][12][13] SOAB material developed by BF Goodrich consists of butyl rubber filled with aluminum. The filler carries microscopic air pockets with it, thus introducing some sound attenuation.…”

Ultrasonically Enhanced Voltammetric Analysis and Applications: An Overview

“…For example in bulk solution, sonolysis in water leads to the hydroxyl radical bought about by dissociation of water inside the cavitation bubble. Simple tests for such radicals include the Weissler test [43,44] solution and the Fricke [45], terphthalate [46,47] and nitrophenol dosimeters [48,49]. Evidence of the degradation products induced by ultrasound was investigated in pioneering work by Riesz et al [50 ± 53] who utilized EPR spin trapping of the non-volatile nitrone.…”
