Side effects of lifesaving drugs given to the triplets as newborns eventually led to deterioration of the inner ear, home of the delicate structures where vibrations are converted to electrical and chemical signals that the brain understands as sound. Without this conversion, sound waves may enter the ear, but we do not “hear.” Hearing is a process in which stimuli (sound waves) are mechanically converted to vibrations that are transduced to neural messages. If one part of this complicated system is compromised, hearing loss results. In the triplets’ case, cochlear implants provide a sense of sound.
