Behavioral testing is used to determine how your child reacts to sound. At a very young age (2-3 months) behavioral observation testing is used to watch for a response from your child in response to sound. The audiologist will look for subtle reactions from your child when a sound is heard, such as when a child stops sucking on a pacifier or bottle.
Visual reinforcement audiometry is used when a child reaches the ages of 4-6 months and is able to sit with limited support from a parent or caregiver. A sound is presented through speakers or earphones. When a child looks to the speaker in the direction from which the sound came, the response is reinforced or rewarded with the illumination and/or animation of toys.
Conditioned play audiometry is conducted when a child is approximately 2.5 years old. A game is played where a child is instructed to react to a sound by dropping a block into a bucket or stacking blocks on a board. To determine how softly and accurately a child can hear speech, the audiologist might ask your child to point to pictures or repeat words.
Otoacoustic Emissions are an automatic response from the inner ear to sound. An earplug presents a series of tones. A small microphone will measure any sounds in response from the inner ear.
