Pediatrics: Testing at Age Two or Older
Children 2 Years and Older
Otoacoustic Emissions (OAEs)
A test in which a series of clicks or tones are placed in the ear canal by a small probe. A microphone within the probe picks up the ear’s response to the sound and sends it to a computer. If the responses are within normal limits, hearing is predicted to be normal.
A test in which a device which changes the pressure within your ear canal and measures how well your eardrum moves in response to the pressure, is placed in your ear. The purpose of tympanometry is to determine how well the middle ear is functioning and the mobility of the eardrum.
Conditioned Play Audiometry (CPA)
CPA makes hearing testing a fun and interactive game for children. The child is instructed, for example, to toss a block in a bucket for each sound heard. They are rewarded with positive social reinforcement (hand-clapping, smiles “good job” etc.). The test can be conducted with sounds coming from a speaker or from earphones. This test is useful with children between 2 and 4 years of age.
At approximately 4 years of age, a child is able to participate in traditional audiologic testing procedures. During this test, a child wears a set of earphones and is instructed to raise a hand as soon as they hear a sound.
