Acoustic Propagation in lined ducts with varying cross-section using a Mild-Slope approximation
Maaz Farooqui, Yves Aurégan, Vincent Pagneux
A modelling of low-frequency sound propagation in slowly varying ducts with smoothly varying lining is proposed leading to an acoustic mild-slope equation analogue to the with mild…
Explicit approximation of the wavenumber for lined ducts
Maaz Farooqui, Yves Aurégan, Vincent Pagneux
For acoustic waves in lined ducts, at given frequencies, the dispersion relation leads to a transcendental equation for the wavenumber that has to be solved by numerical methods. B…
Using liner surface modes in ducts to make obstacles reflectionless
Maaz Farooqui, Yves Aurégan, Vincent Pagneux
Acoustic cloaking for the suppression of backscattering inside ducts is proposed in the audible range where plane waves are curved around the object using the surface modes of the…
Low frequency sound attenuation in a flow duct using a thin slow sound material
Yves Auregan, Maaz Farooqui, Jean-Philippe Groby
We present a thin subwavelength material that can be flush mounted to a duct and which gives a large wide band attenuation at remarkably low frequencies in air flow channels. To de…
