In recent years MRI suites are being installed in malls, office buildings, and other sites where they share space with neighbors. MRI units can generate sound levels as high as 107 dB. These sound levels need to be contained when the units are located next to, above or below other tenants. The additional constrictions of magnetic shielding and special venting and HVAC considerations make acoustic design somewhat challenging. AVL has provided isolation design for MRI suites for the University of Rochester, Presgar, Borg & Ide and others. In each case, we have been able to attain environments where neighbors, as well as waiting patients, do not hear the MRI units in operation.
