Project Challenge

Flexible Acoustic Testing and Fast DUT Access in Compact Anechoic Chamber

  • The telecom testing application required a small anechoic chamber with compact footprint that could support different test configurations while allowing fast and convenient DUT replacement, connection, and reconfiguration without compromising acoustic performance.

Engineered solution

How we solved it

Mini Microdyne® Small Anechoic Chamber with two separate test compartments, a gas-assisted upward-opening acoustic door with wedge absorbers, and a swing door for quick access to the second compartment. High-quality acoustic PU foam provides broadband sound absorption, while a standard I/O feedthrough panel supports measurement and signal connections.
