DPOAE hearing test: what to expect

DPOAE means distortion product otoacoustic emissions. During the test, a soft probe sits in the ear canal and plays tones. A healthy inner ear can produce a measurable response to these sounds; the equipment records whether that response is present at selected pitches. The test is usually quiet, quick, and does not require you to press buttons or describe what you hear.

Earwax buildup, movement, background noise, a poor probe seal, or fluid behind the eardrum can affect the recording. A result that is absent or unclear does not by itself identify the cause or measure every aspect of hearing.

Keep still and quiet while the probe is in place, and tell the tester about ear pain, discharge, recent infection, or a blocked feeling. Do not put cotton buds or other objects into the ear canal. The tester may inspect the ear first and may recommend a full hearing test if the DPOAE result needs more context.

A hearing test can assess hearing in more detail by recording responses to sounds at different pitches and loudness levels. Results should be interpreted alongside symptoms, examination findings, and medical history.

Arrange prompt medical assessment for sudden hearing loss, severe dizziness, new one-sided hearing change, ear pain with fever, or fluid or blood from the ear. Seek urgent care if hearing changes follow a head injury or occur with facial weakness. Do not wait for routine screening when symptoms are sudden or rapidly worsening.

Ask what the result means for each ear, whether earwax or middle-ear fluid could have affected it, whether you need a full hearing test, and when your hearing should be checked again.
