These pulses are understood by the brain to be what a person hears as sound. Hearing loss can occur throughout any part of the ear, and in varying degrees of severity. As hearing loss can affect a child’s ability to develop speech, language, and social skills, it is important to identify any signs and symptoms early in the child’s…
