Application of the frequency analysis of acoustic emission in the study of the metal alloy solidification

open access: yesArchives of Acoustics, 2000
A frequency analysis of the acoustic emission signals was applied for the investigation of the solidification of a Pb-Sb alloy. Spectra of continuous emission and short-time acoustic emission impulses were investigated.

Adaptive Narrowband Compensation Algorithm for Active Control of the Pressure Pulsation Line Spectrum in A Liquid Pipeline System

open access: yesShock and Vibration
Active noise control technology provides a means for actively controlling pipeline pulsations. The control signal emitted by the secondary source feeds back into the reference input signal, thereby generating a pulsation coupling phenomenon.

Acoustic resonance spectra of a finite cylindrical shell [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1988
Previous studies have explained acoustic scattering from an infinite cylinder or a sphere. The scattering depends strongly on resonances that are related to the propagation of circumferential waves when the acoustic axis is perpendicular to the cylinder axis or the propagation of guided waves when the insonification is oblique.

Modeling late reverberation in acoustic echo suppression

open access: yes, 2022
The traditional approach to cope with acoustic echoes is the use of an acoustic echo canceler (AEC). Usually, subband acoustic echo suppression (AES) is used after the AEC to suppress residual echoes which have not been subtracted.

Direct numerical simulation of turbulent flow past a trailing edge and the associated noise generation

open access: yes, 2008
Direct numerical simulations (DNS) are conducted of turbulent flow passing an infinitely thin trailing edge (TE). The objective is to investigate the turbulent flow field in the vicinity of the TE and the associated broadband noise generation.
