Bone Conduction – BERA: What It Is, How It Works, and Why It Matters

What is Bone Conduction – BERA?

Bone Conduction – BERA is a special hearing test. It helps doctors check how well your hearing nerves and brain respond to sound. BERA stands for Brainstem Evoked Response Audiometry. This test uses bone conduction to send sounds directly to the inner ear. Because of this, it can show if there is a problem with the hearing nerve or the ear itself. Many doctors use Bone Conduction – BERA for hearing loss assessment and ENT diagnosis.

How Does Bone Conduction – BERA Work?

During the test, soft sounds are sent through a small device placed behind your ear. This device vibrates gently, sending sound waves through the bone. As a result, these waves reach the inner ear without passing through the outer or middle ear. Special sensors on your head pick up how your brain responds to these sounds. The test records these responses, which are called auditory brainstem responses.

  • First, the doctor cleans small spots on your head.
  • Next, sensors are placed on these spots.
  • Then, a bone vibrator is placed behind your ear.
  • Soft clicking sounds are sent through the vibrator.
  • The sensors record your brain’s response to each sound.

    • Why is Bone Conduction – BERA Important?

    Bone Conduction – BERA is important for many reasons. For example, it helps doctors find out where hearing loss is happening. Sometimes, hearing loss is due to problems in the ear canal or middle ear. Other times, it is due to nerve issues. This test can tell the difference. Because of this, it guides doctors in choosing the right treatment. In addition, Bone Conduction – BERA is safe and painless.
