It is known in the engineering that materials with small multiple co-axial wires, or multi-perforated materials helps to reduce the sound propagating inside the media containing. The difficulty lies in a high density of small holes which makes a direct numerical simulation impossible because the equations to be solved would be too large. However the small holes have a significant influence on the outgoing noise. In this project we study a thin periodic multi-perforated layer ending with two corners singularities with techniques of asymptotic expansion.
