Abstract
The nonlinearity parameter B/A is a basic parameter in acoustics. One effective method for determination of B/A is finite amplitude method, considering the influence of both the sound attenuation of samples and the diffraction of the transducer on the experimental measurement. This paper is about the study on the determination of B/A with low-frequency sound. The experimental results agree well with the theory.
