Hearing is a vital sense that significantly influences our daily interactions and overall quality of life. As humans, we can hear through two different pathways: air conduction and bone conduction.

The traditional method, air conduction, involves the ear canal, middle ear, and inner ear. In contrast, bone conduction bypasses the ear canal and directly stimulates the cochlea by vibrating the bones of the skull. At Aanvii Hearing, we prioritize comprehensive hearing assessments that evaluate both pathways to ensure accurate diagnosis and effective treatment.

The Importance of Bone Conduction in Hearing Assessments:

During a hearing assessment, it's crucial to test both air conduction and bone conduction to understand an individual's hearing capabilities. This dual-pathway approach allows hearing care providers to pinpoint the exact nature of any hearing loss and tailor treatments accordingly.

How Does Bone Conduction Testing Work?

Bone conduction testing is a standard procedure performed during a hearing assessment. While air conduction testing involves using inserts or headphones to deliver sound to the eardrum, bone conduction testing utilizes a bone oscillator. Here is a closer look at the operation of this process:

The Bone Oscillator:

A bone oscillator is a specialized device consisting of a plastic casing over a diaphragm. During the test, this oscillator is placed on the mastoid bone, located just behind the ear lobe. The mastoid bone is an ideal spot because its proximity to the inner ear allows for effective transmission of vibrations.

The Testing Procedure:

Preparation: The patient is seated comfortably in a sound booth an environment designed to minimize external noise and ensure accurate test results.

Placement: The bone oscillator is carefully positioned on the mastoid bone behind the patient's ear.

Sound Delivery: The hearing care provider plays a series of tones through the bone oscillator. These tones vary in frequency and intensity to assess the patient's hearing range thoroughly.

Patient Response: Each time the patient hears a tone, they press a button to indicate their perception of the sound. This response helps the provider determine the patient’s bone conduction hearing level.

What Does the Test Measure?

Bone conduction testing primarily measures the efficiency of the inner ear and auditory pathways. By bypassing the outer and middle ear, this test focuses on the cochlea and auditory nerve, providing critical information about sensorineural hearing loss. If bone conduction results are significantly better than air conduction results, it may indicate a conductive hearing loss, where sound waves are not effectively transmitted through the outer or middle ear.

The Painless, Essential Test:

One of the key advantages of bone conduction testing is that it is completely painless. The vibrations generated by the bone oscillator are gentle and do not cause any discomfort. Patients can relax and focus solely on responding to the tones they hear, ensuring accurate and reliable results.
