Motivated by recent experimental results we test how well various extensions of the well-known coherent potential approximation (CPA) determine the characteristics of the acoustic-wave propagation through a random composite consisting of glass spheres in water. In spite of the approximate character of the methods, our results seem to be in reasonable agreement with recent experimental data.
PACS: 62.30.+d – Mechanical and elastic waves; vibrations / 43.20.Hq – Velocity and attenuation of acoustic waves / 43.35.Bf – Ultrasonic velocity, dispersion, scattering, diffraction, and attenuation in liquids, liquid crystals, suspensions, and emulsions
