In this work the acoustic behavior of a 0.5T head-only scanner is demonstrated. Measurements of the A-weighted equivalent continuous sound level (LAeq) over a 10-second period were made for typical clinical protocols at three locations: magnet isocenter; within the magnet room but outside the magnet bore; and at the operator console – outside of the magnet room. The LAeq values varied between 84-94 dB, 74-81 dB, and 55-57 dB at the three measurement positions respectively. Notably, outside of the MR room, the LAeq levels were indistinguishable from ambient levels, suggesting minimal environmental acoustic impact near the magnet installation site.
