How big is the room? ‒ For most large rooms we would recommend additional shielding layers to attain the desired attenuation Where is the room to be located? ‒ We have specialist measuring equipment and will fully assess the magnetic field within the relevant area so that we can identify regions of high field and classify their frequencies
