Journal Release: An experimental investigation into active structural acoustic cloaking of a flexible cylinder

ISLNE researchers have published a new journal paper: ¡°An experimental investigation into active structural acoustic cloaking of a flexible cylinder¡± published by Elsevier's Applied Acoustics.

The paper , co-authored by PhD researcher Charlie House and his supervisors, Dr Jordan Cheer and Professor Steve Daley , presents an investigation into the use of structural actuation as a mechanism to actively control the acoustic scattering from an aluminium cylinder. This technique, known as Active Acoustic Cloaking , can make an object acoustically transparent, so that its presence in a sound-field has no noticeable effects in the far-field.

The journal article also discusses a number of potential implementation challenges, including the influence that the number of control actuators has on the acoustic cloaking performance, the causality of the control filters, and the effect of the active acoustic cloaking system on the structure itself.
