Ultra-broadband sound absorption in a compact multi-chamber micro-perforated panel absorber with varying depths
(2024)
This study presents an enhanced multi-chamber micro-perforated panel absorber (MC-MPPA) with varying sub-chamber depths, offering ultra-broadband low-frequency sound absorption. Traditional micro-perforated panel absorbers ...

Shear Layer Dynamics of a Cylindrical Cavity for Different Acoustic Resonance Modes
(2010)
This paper investigates the interaction between the shear layer over a circular cavity and the flow-excited acoustic response of the volume to shear layer instability modes. Within the fluid-resonant category of cavity ...
Characterization of Low Noise Technologies Applied to a Full Scale Fuselage Mounted Nose Landing Gear
(The Institute of Noise Control Engineering of the USA, Inc., 2015)
Modelling multi-modal sound transmission from point sources in ducts with flow using a wave-based method
(2009)
An understanding of the multi-modal propagation of acoustic waves in ducts is of practical
interest for use in the control of noise in, for example, aero-engines, automotive exhaust and
ventilation systems. In this paper, ...
TEENI-Turboshaft Engine Exhaust Noise Identification
(2010)
The TEENI project is an FP7 level 1 (Theme 7 ? Transport) 1st Call EU-funded project. It focuses on Helicopter Engine Exhaust Broadband Noise, and tries to identify the origin of this noise from external measurements only. ...
