Recognizing that tiny ears are particularly susceptible to hearing damage, it is important to check noise levels before purchasing them. “Many parents don’t realize the permanent damage a simple toy can inflict on a child’s hearing,” said Dr. Terry, a member of the American Academy of Audiology and with Broadwater Hearing Care. “When we fail to protect a child’s hearing, the result can be irreversible hearing loss.” The inner ear contains delicate hair cells which do not regrow. Once these are damaged by noise, the result is permanent hearing loss.
