Low-Noise MRI Acoustic Shielded Door
Product Performance & Applications
The Low-Noise MRI Acoustic Shielded Door addresses the critical issue of noise transmission from MRI scanners, which can generate sound pressure levels of 80 to 100 decibels during typical scanning sequences. While maintaining RF attenuation of 100 dB across the 5–200 MHz range, this door incorporates advanced acoustic isolation features achieving STC 40 or STC 50 sound transmission class ratings. The multi-layer door core construction combines high-density materials with acoustic damping layers to effectively reduce transmission of both airborne and structure-borne noise.
By reducing noise transmission to adjacent waiting areas, staff workstations, and corridors, this door improves patient comfort and reduces anxiety associated with the loud, rhythmic sounds of MRI scanning sequences. The reduced noise exposure also benefits staff working in proximity to the MRI suite over the course of their careers. The acoustic properties complement the electromagnetic shielding function, addressing both patient experience and staff welfare concerns.
The door uses the same non-magnetic materials and pneumatic sealing system as the standard MRI door, ensuring full MRI compatibility while achieving superior acoustic performance. Construction includes multi-layer wood panels with melamine coating, stainless steel, and aluminum components—all selected for their non-magnetic properties and acoustic performance characteristics. The pneumatic sealing system ensures consistent RF tightness while also contributing to acoustic isolation by eliminating gaps that could transmit sound.
