The paper describes an improved thermodynamic method for measurements of
characterizing acoustic nonlinearity parameter B/A of liquids and biological media. The method is based on measurement of small variation of sound speed with static pressure in an adia-batic process. Phase-comparative technique is applied in order to get high sensitivity. only about one Atm. static pressure is needed, the measurements are much easier to carry out than traditional techniques previously used. Results from measur...
