Acoustic Mesh

Acoustic mesh is a precisely woven wire mesh designed to control sound attenuation and airflow resistance. It’s engineered to achieve a defined Rayl value, a measure of acoustic impedance that determines how sound waves pass through or are absorbed by the material. Gerard Daniel manufactures acoustic mesh for aerospace applications, such as nacelles and thrust reversers, as well as for consumer electronics where noise suppression is critical.

In aerospace, acoustic mesh is integrated into jet engine nacelles, thrust reversers, and exhaust liners to reduce engine noise while maintaining airflow. Gerard Daniel’s meshes are woven to strict Rayl and OEM specifications to meet the performance and regulatory standards of major aircraft manufacturers and aftermarket service providers.

The Rayl value measures the airflow resistance or acoustic impedance of a mesh. A higher Rayl value indicates greater resistance and more sound absorption, while a lower value allows more airflow. Gerard Daniel weaves mesh to Rayl values ranging from 3–100+ on the CGS scale and 30–1000+ on the MKS scale, or to any custom Rayl value specified by the customer.

Acoustic mesh can be woven in a variety of patterns depending on the desired porosity and sound attenuation characteristics. These include plain square weave, Dutch weave, reverse Dutch weave, and twilled weave designs. The finer Dutch and twilled weaves are typically used for high-performance acoustic control.

We typically use stainless steel, Inconel^®, Monel^®, and Nickel-based alloys that can withstand extreme temperatures, vibration, and corrosion common in aerospace environments. Material choice depends on acoustic requirements, durability, and compliance with specific OEM material standards.

Our weavers continuously monitor and measure Rayl values in real time during the weaving process. This allows for minute adjustments before the mesh is certified in our quality lab, ensuring every batch meets exact acoustic specifications and OEM standards.

Yes. Many customers send us samples with unknown Rayl values. Our team measures the acoustic impedance, identifies the weave and material, and either matches the performance or recommends an optimized mesh design for the target application.

Gerard Daniel routinely manufactures mesh to meet aerospace specifications, such as:

SMS 54 Issue 4, NRM 1-2 Revision F, PWA 1170 Revision P, AMS 5690 Revision M, and RPS 17.34 Revision H, among others. We maintain full documentation for traceability, cleanliness, and part marking per customer and regulatory requirements.

Because every acoustic mesh is woven to customer-specific Rayl values and specifications, we only stock items under our Customer Replenishment System. However, we can quickly prototype new meshes to match existing parts or evaluate performance in new designs.

Simply contact our engineering team with your target Rayl value, application details, or a physical sample. We’ll collaborate to confirm your acoustic performance requirements and deliver prototype meshes or production runs tailored to your specifications.
