We start with a short chat: when you noticed it, which ear, any ringing, dizziness or noise at work. That tells us what to look for. At the end we go through the audiogram with you and anyone you bring, and you take a printed copy home.
What is pure tone audiometry (PTA)?
Pure tone audiometry is the main hearing test. You sit in a sound-treated booth wearing headphones. The audiologist plays beeps from low pitch (250 Hz, like a drum) to high pitch (8000 Hz, like a bird). Each beep gets softer until you can only just hear it. That softest level, in decibels, is your threshold for that pitch.
We test each ear on its own. We then repeat the test with a small vibrating band behind the ear, called bone conduction. It skips the outer and middle ear and goes straight to the inner ear. If both results match, the loss is in the inner ear or the nerve (sensorineural). If bone conduction is much better, something in the outer or middle ear is blocking sound (conductive), such as wax or fluid. That difference decides whether a hearing aid or an ENT doctor is the right next step.
What is tympanometry or impedance audiometry?
Tympanometry checks the middle ear, the small air space behind the eardrum. A soft rubber tip sits at the entrance of your ear canal and gently changes the air pressure for a few seconds. The machine measures how the eardrum moves. A flat result can mean fluid behind the eardrum, a blocked Eustachian tube or a hole in the eardrum. The same probe can measure the acoustic reflex, a tiny muscle response to loud sound that helps confirm where a hearing problem sits. It is quick and painless, and it matters most for children and anyone with a recent cold or blocked feeling.
What does speech audiometry show?
Two people can have the same audiogram and understand speech very differently. Speech audiometry finds the softest level at which you can repeat simple words, then checks how many words you get right at a comfortable volume. A good word score means a hearing aid is likely to help a lot. A low score tells us to set honest expectations, and sometimes to look at other options such as a cochlear implant.
