Simultaneous evaluation of acoustic nonlinearity parameter and attenuation coefficients using the finite amplitude method
A novel method to determine acoustic parameters involved in measuring the nonlinearity parameter of fluids or solids is proposed. The approach is based on the measurement of fundamental and second harmonic pressures with a calibrated receiver, and on a nonlinear least squares data-fitting to multi-G...
