Sonura promotes newborn development in the neonatal intensive care unit (NICU) via auditory protection and parental connection. Newborn infants are exposed to harmful alarm sounds for over 12 hours each day in the NICU. They are separated from their parents, eliminating developmentally important human connection. Sonura solves these deficiencies using a beanie that blocks harmful noises while providing an audio messaging system so infants can hear their parents’ voices often.
