Acoustic mesh is used to achieve precise sound attenuation objectives used in aerospace (typically nacelles and thrust reversers) and consumer electronic applications. It is woven to a precise Rayl value, which is a measure of acoustic impedance or airflow resistance.
Acoustic mesh can be woven from a wide range of mesh types, from plain square mesh with a greater open % area, to complex Dutch, Reverse Dutch, and Twilled weave patterns designed to produce a much finer open area and sound attenuation qualities. The latter is far more common in most acoustic applications.
Our experienced weavers bring many years of experience and knowledge in weaving acoustic mesh. What sets us apart is our efficiency and accuracy – for example, we continually measure the Rayl value of the mesh as it’s being woven and can make minute tweaks to ensure that it stays in specification even before it’s officially certified to the Rayl value in our quality lab.
We have the capability to weave acoustic mesh to meet Rayl values in the following ranges;
- 3 – 100+ on the CGS scale
- 30 – 1000+ on the MKS scale
We can also weave to a custom Rayl value. Often a customer will send us a sample with an unknown Raly value and ask us to match the performance. Our skilled weavers and engineers will work with them to match it or advise the most suitable mesh depending on the application.
