Testing Young Children
Young children sometimes do better if they play games. There are ways to test your child’s hearing through play. The most common ways are visual reinforcement audiometry (VRA) and conditioned play audiometry (CPA).
Conditioned Play Audiometry
Air conduction audiometry is the most common type. This type of testing is good for toddlers and preschoolers, ages 2-5. Your child will do something each time she hears a sound.
Visual Reinforcement Audiometry
This is the best way to screen children between 6 months and 2 years old. The audiologist will teach your child to look to where the sound came from When your child looks in the direction of the sound, he sees a moving toy or flashing light. This rewards your child for looking at the sound. Both ears are tested at the same time.
Bone Conduction Testing
Audiologists use this type of testing when something, such as wax or fluid. is blocking your outer or middle ear. For this test, the audiologist will put a small device behind your ear or on your forehead. The sounds sent through this device cause your skull to gently vibrate. This vibration goes to the inner ear, or cochlea, and skips the outer and middle ears.

The audiogram is a graphical representation of the results of a pure-tone hearing test. It shows how loud sounds need to be at different frequencies for you to hear them. These hearing tests show the type, degree, and composition of hearing loss.
The audiogram shows your hearing thresholds in decibels (dB) hearing level (HL) for each tested frequency. A normal hearing threshold is considered to be 0-25 dB HL. Hearing loss is categorized as mild (26-40 dB HL), moderate (41-55 dB HL), severe (56-70 dB HL), or profound (71+ dB HL).
Different types of pure tone audiometry tests exist, such as air conditioning, bone conditioning, and speech audiometry.
