What is an audiometry test?

Audiometry tests examine air conduction and bone conduction to determine a person's hearing ability. Air conduction means that the sound waves reach the inner ear through the ear canal, eardrum and the middle part of the ear. Bone conduction means the passage of sound through the bones around the back of the ear.

Why is an audiometry test done?

Audiometry test is done to check a person's hearing ability. This can also be done during regular health check ups. This test becomes mandatory when a person has persistent hearing loss. There can be many reasons for hearing loss, such as:

• - birth defect
• - ear infection
• - ear injury
• - inner ear diseases
• - constantly hearing loud noises
• - ear piercing

Deafness caused by any type of injury or disease inside the inner ear is called sensorineural hearing loss. It can also happen if the hair cells of the cochlea fail to function properly or the nerves that carry sound signals to the brain are damaged. Deafness in such situations is permanent, but in most cases it is only a moderate to severe condition.

Most health care organizations recommend regular audiometry tests for people who are usually exposed to loud noises. For example, teens who listen to loud music should get their hearing checked up regularly.

How to prepare for Audiometry Test?

Audiometry test does not require any special preparation. Instructions related to the test will be given before the test, these instructions must be followed carefully. There is no risk in this test because it is a simple test, which does not require injection or incision etc.

During Audiometry Test

How is an audiometry test done?

The audiometry test can be started as a simple hearing test in a clinic. The person has to answer some questions, in which they are asked about the problems they are experiencing while listening and the ability to hear etc. Then during a simple test procedure, the patient may be asked to listen for whispers or to identify the sound of the tuning fork or ear

However, to accurately test hearing, these tests are done:

Audiogram:

This is also known as pure tone testing, during which the doctor will ask you to wear earphones connected to the audio meter. In this test, only one ear is examined at a time. The doctor will ask you to indicate when you hear a sound. While doing this test, the doctor will make a note of the minimum intensity you need to hear each tone or how loud the sound should be. In addition, a bone oscillator is also placed in front of the mastoid bone to test bone conduction.

 Speech audiometry: The speech audiometry test examines a person's ability to understand and hear words spoken at different levels of voice (rapid or slow), which are pronounced by a head set.

 

Emittance Audiometry:

With the help of this test, the function of the eardrum and the sound emanating from the middle ear is checked. For the test, a type of instrument called a "probe" is inserted into the ear to prevent air from entering the ear. The probe pumps air into the ear at regular intervals so that no pressure builds up in the ear. After this, the response of the eardrum to different levels of pressure and sound intensity is recorded, to determine how much sound is flowing into the ear.

• What do audiometry test results indicate?

 The following are called normal results:

be able to hear low-pitched sounds without pain or effort

wind and bone hear the tuning fork

Hearing a tone of 250 to 8000 Hz or less at 25 decibels during an audiometry teste.

In abnormal results, the patient does not hear a loud or low sound. Hearing loss occurs when a person stops hearing sounds below 25 decibels.
