Similarly, an ear infection can affect a child's hearing acuity, and the child may miss important information in school or at home. This is true even if the child's hearing has been tested previously and found to be completely normal. Therefore, it is important for parents and caregivers to keep an eye out for any signs that a child may be having difficulty hearing, such as saying “Huh?” or “What?” or requesting that the television be tuned louder.
