Phased microphone array beamforming has become a standard technique to localize sound
sources. For localization of rotating sound sources at free-space conditions in the frequency …

A method is presented for the location of rotating sound sources by a microphone array. In
contrast to other methods which are formulated in the time domain, this method works …

The exact frequency domain solutions of the noise for rotating point sources are extended to
acoustic modal domain. Moreover, the modal analysis method from the aerodynamic …

This paper focuses on the radiation modes and efficiency of propeller tonal noise. The
thickness noise and loading noise model of propellers has been formulated in spherical …

Abstract The Modal Composition Beamforming (MCB) method can quickly achieve the
localization of fast-rotating sound sources; however, its low resolution and unclear applied …

This paper deals with the use of the Ffowcs Williams–Hawkings equation for hydroacoustic
analysis of rotating blades, and the deep difference between the acoustic fields generated …

PHASED microphone array beamforming has become a standard technique to localize
acoustic sources of both stationary and moving objects in the past decades [1]. Rotating …

Identifications of rotating sound sources are of interest in many industrial applications.
Nowadays, almost all frequency-domain rotating beamformings are based on the concept of …

An inverse acoustic method is presented in this work, which allows to determine the spatial
and temporal distribution of unsteady rotating forces from microphone array measurements …

Identifications of rotating sound sources are of interest in many industrial applications. The
most famous beamforming to identify rotating sound source is the time-domain ROSI …
