Diagnosis Of Hearing Loss

If you're experiencing trouble hearing, see your doctor. They'll inspect your ears and run some basic hearing tests on you. The diagnosis for hearing loss are discussed below.

Examination of the ears

An auriscope (or otoscope) is a tool with a light at the end that is used during an ear examination to look for anything abnormal, such as:

-an ear canal infection

-an obstruction caused by earwax, fluid, or an object

-a bulging eardrum – indicating an infection inside the middle ear

-fluid behind the eardrum – known as glue ear

-a perforated eardrum 

-a collapsed ear drum

-skin collected in the middle ear (cholesteatoma)

-The skin of a deflated eardrum accumulated in the middle ear (cholesteatoma)

Your doctor will inquire as to whether you have any ear pain and when you first noticed the hearing loss.

A specialist is referred to you

Your general practitioner (GP) may recommend you to an ENT specialist or an audiologist (a hearing specialist). Further hearing tests will be performed by the specialist in order to discover the cause of your hearing loss and to prescribe the best course of therapy.

A hearing test may contain one or more of the following:

-Tuning fork evaluation (sometimes performed by your GP)

-Bone conduction test with pure tone audiometry

The following are the results of these tests.

Tuning fork evaluation

A tuning fork is a metallic Y-shaped device. When lightly tapped, it produces sound waves of a predetermined pitch that can be used to test various parts of your hearing.

The tester makes the tuning fork vibrate by tapping it on their elbow or knee, then holding it at various locations around your head.

This test can establish whether you have conductive hearing loss (hearing loss caused by sounds not being able to travel freely into the inner ear) or sensorineural hearing loss (hearing loss caused by a malfunction of the inner ear or hearing nerve).

Audiometry with pure tones

Both ears are tested using pure tone audiometry. An audiometer is used to create noises of varied levels and frequencies throughout the test (pitches). You listen to the noises through headphones and answer by pressing a button when you hear them.

Test of bone conduction

In adults, a bone conduction test is frequently performed as part of a normal pure tone audiometry test. It is used to determine if you have sensorineural hearing loss by assessing how effectively your inner ear functions.

A vibrating probe is placed on the mastoid bone behind the ear for bone conduction. It assesses the audibility of noises conveyed through the bone.

Bone conduction is a more advanced variant of the tuning fork test that, when combined with pure tone audiometry, can assist determine whether hearing loss is caused by the outer and middle ear (conductive hearing loss), the inner ear (sensorineural hearing loss), or both (sensorineural hearing loss).
