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

# Record card
14
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.

Piezoelectric tuning-fork sensor for scanning probe microscopy with high sensitivity

# Record card
37
Description

Quartz tuning forks are employed in scanning atomic force microscopy (AFM), as well as in some derived techniques, as high sensitivity detectors of interactions, of both conservative and dissipative kind, between the AFM nanometric probe and the investigated surface. However, the contributions of the two kinds of interaction result as convoluted in the sensor response, preventing fully quantitative measurements of the quantities of interest.
