Numerical and experimental study of Near-Field Acoustic Radiation Modes of a baffled spherical cap
Z.H. Liu,Cédric Maury +1 more
TL;DR: In this paper, the acoustic radiation modes (ARMs) of spherical structures are studied using the pressure-Velocity (PV) method, which yields the active and reactive modes, which refer to the radiated and non-radiated sound power components respectively, without restrictions on the observation distance.

Experimental Synthesis of Spatially-Correlated Pressure Fields for the Vibroacoustic Testing of Panels
TL;DR: In this paper, the problem of reproducing random pressure fiels on plane structures for the measurement of their vibroacoustic properties is investigated using different reproduction approaches and a synthetic array, the main application is the simulation of a Turbulent Boundary Layer excitation in a laboratory environment, as an alternative to in-flight or wind tunnel experiments.

A tutorial on the representation of two-dimensional wave fields by multidimensional signals
TL;DR: In this paper, the authors present a framework for describing wave-like signals based on transform domain signal descriptions from multidimensional systems theory, which is based on well-known transform-domain signal descriptions.
