Two-point radiation statistics from large-scale turbulent structures within supersonic jets:
TL;DR: The noise from large-scale coherent turbulent structures within jets remains the dominant source of noise in jets as discussed by the authors, and for the purpose of developing future control systems for the large scale noise source, the authors investigate the use of large scale coherent turbulent structure within jets.
Journal ArticleDOI
Blind separation of sound sources from the principle of least spatial entropy
TL;DR: In this paper, the authors propose a method for separating incoherent and compact sound sources which may overlap in both the space and frequency domains, by backpropagating the pressures measured by an array of microphones to the source domain.
Journal ArticleDOI
Theoretical study of acoustic circular arrays with tangential pressure gradient sensors
TL;DR: A theoretical analysis of circular microphone arrays that do not measure the sound pressure but the component of its gradient that is tangential to a given boundary is presented, compared to that of a conventional pressure sensor array as a benchmark.

Localisation et contribution de sources acoustiques de navire au passage par traitement d’antenne réduite
TL;DR: In this paper, the authors propose a method for the identification of sources and the contribution relative of chacune de ces sources dans the signature acoustique du navire.

Optimal spatial sampling for spherical loudspeaker arrays
TL;DR: An optimization method for choosing loudspeaker locations and driving functions in such a constrained environment is presented to allow for selective optimization of both low spatially-varying components and azimuthal components.
