Acoustic non-linearity method for estimating the ratio of bound to free water of biological media.
The acoustic non-linear properties of bound and free water in biological media are treated based on their structural differences. A model describing the different effects of bound and free water in protein-water solutions and in biological media is proposed. The ratio of bound to free water can be estimated from this model from measurements of the acoustic non-linearity parameter B/A, the sound speed, and the density of the specimens.
