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

# Record card

Description

The invention is about the development of a device and its methodology for measuring the active and reactive sound intensity from the impedance computation. The active intensity is calculated directly in the frequency domain multiplying the complex impedance and power spectrum of the air particle velocity. A second line of post-processing is applied to obtain the overall complex sound intensity.
