High levels of acoustic noise in neonatal MRI can lead to anxiety, motion artifacts, and incomplete examinations due to newborns waking up. Hearing protection is often complicated to apply properly on neonates and there is often an uncertainty if the hearing protection is having the intended effect. Acoustic noise levels during our neonatal MRI studies range from 80-112dB (A-weighted). We have developed a new simple, safe and reliable method for substantial reduction of the acoustic noise (6-24dB). An acoustic hood of dampening materials is placed inside the MR tunnel attenuating the noise and providing a safer environment for the infant.
