It is worth noting that such a much more sophisticated model, based on multiple scattering theory, provides the same results as those obtained with the Kuster-Toksz model based on single scattering theory.

"What is the Young's Modulus of Silicon? The dispersion effects are therefore negligible in this frequency range and then the use of the described cut-off procedure is justified here. This website uses cookies to provide you the best experience. The reason is simply that rubber has a very low modulus of elasticity compared with most solids which have Youngs modulus of order $10^{11}$ Pa, not $10^6$, speed of oscillation of particle doesn't affect the speed of wave propagation. Solid lines refer to the Kuster-Toksz model (Eqs 2(a) and 2(b)) with K0=1.2GPa, G0=0.3MPa, 0=1040kg/m3 for the soft silicone rubber matrix, and K1=0.14MPa, G1=0, 1=1kg/m3 for the air cavities. 2(b), the best fitting curves also provide exponents n of about 1.5, as observed for the non-porous sample, but the order of magnitude of 0 is a thousand times greater, that is probably due to scattering losses.

Conclusions: I have absolutely zero experimental experience :). Effects of fine metal oxide particle dopant on the acoustic properties of silicone rubber lens for medical array probe. What does "up to" mean in "is first up to launch"? The speed of sound in any chemical element in the fluid phase has one temperature-dependent value. However, in the case where the incident wavelength 0 of the propagating elastic wave is much longer than the pore size a, various more-or-less simple models have been reported to describe the effective properties of porous materials in the quasi-static limit16. McGraw-Hill. A. Cafarelli. J. Micromech. The Kuster-Toksz model only providing quasi-static expressions for the effective properties of the porous media, it is not expected to give full account of dynamical (frequency-dependent) quantities such as attenuation coefficients. The photograph of the 19%-sample is not shown here because it has the same appearance as the 12%-sample.

Andrea Cafarelli, Piero Miloro, Antonella Verbeni, Marina Carbone, Arianna Menciassi declare that they have no conflict of interest. $$v = \sqrt{ \frac{\text{Elastic properties}}{\text{Inertial properties}}} $$. Depending on the 'quality' of the material (presence of fillers, cross-link density, base polymer molecular mass etc) may therefore not even bounce back to $0.9\:\mathrm{cm}$. The sound-speed measurements reveal a sudden drop of the phase velocity cL with the porosity for longitudinal waves, while the transverse phase velocity cT remains constant as shown in Fig. Naval Coastal Systems Laboratory, Panama City, Florida 32401. 2022 May;6(5):541-558. doi: 10.1038/s41551-022-00890-6.
