The study is the flexibility coefficients and attenuation coefficient of ultrasound as a relationship in the composition of the samples prepared, a two groups The results showed that the density and velocity supersonic and the flexibility coefficients, as well as attenuation coefficient depends on the installation of samples, leading to split each group into two Turkeptin.
