Hearing assessments are straightforward and simple. But most importantly, they are painless, non-invasive and easier than most people realise. With that in mind, let’s take a closer look at what to expect.
Collecting Your Hearing History
Your audiologist will take a brief hearing history, looking at what may be behind potential hearing loss and the impact this may be having on your lifestyle and relationships.
A Physical Exam of the Ear
Your audiologist will inspect the ear canal with a light called an otoscope. This is to check for physical problems that block the passage of sounds, such as earwax buildup or polyps.
Hearing Assessments
Your audiologist will then assess your hearing in a variety of ways. These different tests all give valuable information about different aspects of your hearing. This helps identify the root cause of any issues. This localisation is important because hearing is a complex process that involves air vibrations (sound) being changed into mechanical energy inside the middle ear, then electrical energy in the inner ear, and finally nerve impulses sent to the brain.
The types of hearing tests include:
Pure-tone audiometry:
For this test, a variety of sounds of different pitches and volumes are played into headphones. You press a button each time you hear the sound. This allows your audiologist to chart what you can and can’t hear.
Speech recognition:
Speech recognition tests your ability to distinguish speech without the presence of visual clues like lip movements or facial expressions. During this test, speech is played through the headphones. Many patients are asked to listen to speech against background noise, which can be an important test when hearing loss has been untreated for some time.
Bone conduction assessment:
This painless test measures how well sound conducted through your bone is detected by the inner ear. It also tests the efficiency of the inner ear and the hearing nerves. The test simply involves a small vibrating probe being placed against your skull, just behind the ear.
Whilst the list of assessments may seem overwhelming, they each play an important role in diagnosing hearing loss and the impact it may be having on your life.
If weakness in your hearing ability is identified, your audiologist may conduct a hearing device demonstration and possibly a hearing device fitting. For this purpose, it can be exceptionally helpful if you are able to attend your appointment with someone who has a familiar voice. As there can be quite a bit to take in, many of our patients tell us they find it useful to have another “set of ears” at the appointment.
