Hemi-Anechoic Chamber for Aerospace Acoustic Testing

IAC Acoustics delivered a specialized acoustic test chamber for aerospace testing, designed to provide a highly controlled acoustic environment for demanding test applications.

Project Summary

High-Performance Acoustic Isolation for Aerospace Testing

Aerospace testing requires a controlled acoustic environment with high levels of sound isolation and low-frequency vibration control, with special access plug panels and opening. The chamber was designed with a 6.5 Hz floating floor and a double-wall construction to provide the required isolation while supporting demanding aerospace test conditions.

Engineered solution

How we solved it

IAC developed a hemi-anechoic acoustic chamber with a 160 Hz cut-off frequency.

The acoustic treatment incorporates Metadyne® 2000 technology, while the double-wall construction and floating floor provide additional acoustic and vibration isolation.
