What is an audiology test?
An audiology test is conducted with an audiometer, an instrument that measures an individual’s sensitivity to various frequencies.
The audiologist will also inspect the ear drum with an otoscope.
Other forms of audiological screening include:
- Otoacoustic emissions: A small probe is inserted into the ear to evaluate cochlear capability.
- Auditory brainstem response: Electrodes on head measure electrical activity to perceived sound.
- Acoustic immittance testing: Evaluates muscle reflex and vibrations of various parts of the ear to determine the location of hearing loss. This is done with a small probe.
Do you need an audiology test?
If you experience some of these symptoms, you may need to be tested:
- Difficulty understanding speech
- You are perpetually exposed to an environment with sound that exceeds 80 decibels

Signs and symptoms of hearing loss in children and infants:
- Delayed speech
- Prolonged ear infections
- Prenatal exposure to Rubella (German measles) or cytomegalovirus
