An experimental apparatus was developed to measure, over a wide range of pressure, the acoustical nonlinear parameter B/A with an uncertainty of 2.2% in order to study the influence of pressure on the value of this parameter in liquids. The experimental technique rests on an improved thermodynamic method which uses a highly sensitive phase comparison technique to measure the change in speed of sound with pressure. The apparatus was then used to measure B/A in water within the pressure range from 0.1 to 50 MPa and at temperatures of between 303.15 and 373.15 K. The data obtained were compared with those in the literature which come from numerical derivation of speed of sound measurements.
