Audiometry Test: Understanding Hearing Tests & Diagnosis

Audiometry measures hearing ability to diagnose loss type/severity and monitor treatment effectiveness. Conducted by audiologists using an audiometer to present sounds at varying frequencies/intensities.

Test Types

• Pure-tone audiometry: Most common. Patient responds to tones via headphones in soundproof room. Creates audiogram (hearing levels by frequency).
• Speech audiometry: Assesses speech understanding—patient repeats recorded words.
• Tympanometry: Measures eardrum movement; identifies middle ear issues (fluid, perforation).
• Otoacoustic Emissions (OAE): Measures inner ear sounds; screens newborns/young children.
• Auditory Brainstem Response (ABR): Measures brain response to sound; for infants, sedated/unconscious patients.

Practical Details

Generally painless, 30–60 minutes. Some discomfort from headphones or probe placement possible.
