MRI scanners produce significant sound pressure levels (SPLs), sometimes in excess of 120 dBA. While the effect of these SPLs has been explored for adult patients, it is currently unknown how they affect neonatal patients. One approach to understanding the effect of this noise exposure on infants is to use existing experimental data that associates a given sound level to a hearing outcome in adults and re-interpret it with respect to infants. This approach requires modeling the differences between the adult and infant hearing apparatus—outer (pinna + concha + ear canal), middle and inner ear. In this presentation, we will present simulations of the infant ear canal SPL gain and compare it to the expected acoustic exposure of the neonate during MRI brain procedures to better understand the effects of MRI noise on the neonatal ear.
