Metallic Anechoic Wedges
Advanced Acoustic Absorption for High-Precision Test Environments
Metallic anechoic wedges are engineered acoustic absorption structures designed to create reflection-free environments for accurate sound testing and measurement. Built using precision perforated metal casings and high-density acoustic cores, these wedges offer exceptional durability, fire safety, and long-term acoustic stability.
Unlike conventional foam absorbers, this metallic wedge system is developed for industrial, research, and high-performance testing chambers where structural integrity, hygiene, and environmental resistance are essential.
Product Overview
These wedge-shaped acoustic modules are installed on chamber walls and ceilings to absorb incident sound waves. Their geometric profile forces multiple internal reflections, allowing acoustic energy to dissipate effectively within the absorptive core.
They are widely used in anechoic chambers, NVH testing facilities, acoustic laboratories, and electroacoustic measurement spaces. The metallic construction ensures consistent acoustic performance even in demanding industrial environments where foam solutions may deteriorate over time.

Key Benefits
This solution provides superior sound absorption while maintaining mechanical robustness. The rigid metal structure prevents deformation and ensures consistent performance over time. It offers excellent resistance to heat, fire, and environmental wear, making it suitable for high-risk or heavy-use facilities.
The modular design allows easy installation and maintenance without compromising acoustic integrity. Its construction reduces long-term replacement costs compared to foam absorbers while delivering stable acoustic results for precision testing environments.
Compliance with industrial safety standards is another major advantage. The non-flammable design enhances facility safety, particularly in laboratories and testing chambers where fire risk must be minimized.
Applications
These acoustic wedges are used in environments requiring high measurement accuracy. Applications include automotive NVH testing chambers, aerospace acoustic testing facilities, electroacoustic product testing labs, and research institutions.
Industrial noise testing spaces rely on this system for reliable sound control under demanding operational conditions. It is also installed in defense, telecommunications, and advanced research facilities where precision acoustic control is essential.
Advantages Over Traditional Foam Absorbers
Foam absorbers can degrade due to humidity, temperature, and aging. In contrast, metallic wedge constructions provide long-term structural stability and resistance to environmental stress. The metal casing protects the internal core while maintaining acoustic transparency.
Fire resistance is a key differentiator. This design eliminates risks associated with combustible foam materials, making it suitable for industrial and regulated environments. It also offers better mechanical protection against accidental impact or wear.
