Product Description

AlphaSorb® Anechoic Foam (formerly AlphaSorb® Max Wedge Foam) provides maximum absorption and is ideal for testing rooms, research facilities, and anechoic chambers along with massive spaces like auditoriums, arenas, and industrial buildings for OHSA compliance. This acoustic foam can dramatically improve the accuracy of sound measurements by eliminating bounce-back sounds such as echo, feedback and resonance. The deep wedge pattern and 6 in. thickness offers maximum absorption and increased mid to low frequency response with an impressive Noise Reduction Coefficient (NRC) of 1.25.

The bold, geometric design of this 3-point anechoic wedge can be used in suspension systems or adhered directly to walls in a variety of patterns to create visual interest and maximize the acoustical performance. Lightweight and easy to install, the anechoic wedges are the perfect solution to your demanding sound absorption applications. AlphaSorb® Anechoic Foam may be manufactured in custom sizes to specification for testing chambers. Please contact us with your project requirements.

NOTE: This product has been transitioned to a new manufacturing process. Material may vary slightly to previously ordered material.
