There are a number of different techniques used to test hearing in children. In this video, Catherine Moyer, AuD., a pediatric audiologist at Rady Children’s Hospital San Diego, administers a hearing screening to a four-year-old child using a technique called conditioned play audiometry (CPA). CPA is essentially a fun and interactive “Listen and Drop” game commonly used to test hearing in preschoolers (ages 3-5). A child is trained to perform an activity each time he or she hears a sound. The activity may involve putting a block in a box, placing pegs in a hole, or putting a ring on a cone. The game is taught before a child puts on headphones. Because CPA requires cooperation from the child, parents are often asked to practice this “listening game” at home.
