We designed a new acoustic hood for neonatal MRI exams at 7 Tesla. The new design is lightweight and allows easy access to the neonate during the MRI examination. We were able to optimize the new acoustic hood to a noise reduction of 10.6dB, exceeding the damping of a prototype with damping of 3.1dB. The new hood was designed to fit a head coil and allows the use of a ventilation tube.
