METHOD FOR MEASURING COMPLEX ACOUSTIC INTENSITY WITH THREE-DIMENSIONAL RADIATIVE AND OSCILLATORY SPECTRAL RESOLUTION

摘要

Method for measuring the spectra of the radiating and oscillating acoustic intensity in any operating condition, minimizing the experimental error. Such method is based on the analysis of the acoustic impedance and on the spectrum of the mean square velocity and on the spectrum of the mean square pressure of an acoustic particle, i.e. on the vibrations of the medium.
