- Measuring the acoustic pressure in an acoustic standing wave field is essential as a means to study acoustic levitation and other related techniques. In this work it was shown that the pressure of an acoustic standing wave field could be measured on line, in a non-contact way, using a scanning Laser Doppler Vibrometer (LDV), where the LDV output is proportional to the integral of the acoustic pressure over the laser path. In the method used to measure acoustic pressure, first, the LDV outputs, υ sLDV and υ eLDV , are obtained by using both COMSOL-MATLAB-based (CM) co-simulation and through experimental measurements. Next, the acoustic pressure distribution is obtained using a MATLAB-based programme and this is reconstructed by using υ sLDV and υ eLDV , based on the Hankel-Fourier (HF) algorithm. Further, the acoustic pressure measurements obtained by using these two methods are cross compared, in that way to demonstrate the effectiveness of the method presented.
