ETS-Lindgren reverberation chambers provide a diffuse-field environment that enables sound absorption tests, sound power tests, and transmission loss studies to be performed.
Series 71 RF Modular Shielded Room
The Series 71 features a double layer of 550mm x 550mm x 3.8mm copper screen mesh weave to deliver excellent attenuation levels, while allowing for air passage through the screen mesh. Copper is highly recommended for use in shielded screen rooms due to its conductivity and oxidation properties. At the same time, a copper screen mesh affords “hear-through, see-through” advantages

An MRI scanner is essentially a large, permanently active electro-magnet. They are used to diagnose and monitor patients with diseases or injuries. The magnetic fields proceed by MRI scanners are significant and are generally required to be contained within the bounds of a shielded room.
MRI scanners are highly susceptible to interference from external radio frequency signals. Interference can cause image quality problems for MRI procedures, reducing or completely spoiling the quality of the scan.
