A pure tone audiometry is used to determine the faintest tones you can hear at a variety of pitches. You will be asked to wear headphones and sit in a sound booth for the duration of the test. Tones will be played through the headphones and every time you hear one you will either raise your hand or press a button.
The results from this test will be recorded on an audiogram, which is a visual representation of how well you can hear.
This test can also be used with children. Instead of using a headphone, sounds are broadcast through speakers in the booth. However, this test is no longer able to distinguish between unilateral hearing loss without the use of headphones.
Visual reinforcement audiometry is used for children between six months and two years old. Instead of raising their hand when a tone is played, the child is trained to look toward the source of the sound. Every time they give a correct response they are rewarded with a visual reinforcement. This usually comes in the form of watching a toy move or a flashing light.
Conditioned play audiometry is used to test children from two to five years old. Sound is broadcast through a speaker and the child is trained to perform a task every time they hear a tone. This task can be putting a block in a box or placing a ring on a cone.
