Application of acoustic horns for the amplification of a p-v probe velocimetric signal

The present paper shows the comparison between experimental data and simulated results for the amplification factor of acoustic horns. The experimental setup was based on a sound insulation enclosure and a Microflown p-v probe, while COMSOL 4.4 software package has been used for numerical simulation. Apart from systematic errors, due to the mismatch between the simulated and experimental sound fields, the behavior of the obtained results shows a good agreement with the COMSOL modeled ones, so confirming the effectiveness of the horn device as a natural amplifier of the velocity signal.
