Typically, the idea of hearing aids conjures up the thought of conventional devices that raise the volume of sound through the canal of the ear. But for people with specific types of hearing loss, particularly those coping with chronic ear issues or single-sided deafness, a different type of technology could provide better quality and comfort: bone conduction hearing devices.

How Bone Conduction Hearing Devices Work

With bone conduction hearing devices, the outer and middle ear are bypassed. Rather than relying on airwaves to transmit sound, these devices utilize the skull’s bones to channel vibrations directly to the cochlea, the inner ear’s sound-processing center. This means that even when the ear canal is obstructed or damaged, sound can still reach the auditory nerve. Consider this example: When you cover your ears and still manage to hear the sound of your own voice when speaking, that’s an example of bone conduction working.

Bone Conduction vs. Traditional Hearing Aids

Conventional hearing aids increase sound and direct it into the ear canal. This works effectively for people who have sensorineural hearing loss, where the inner ear or auditory nerve is damaged. But if the issue is with the outer or middle ear, due to infection, fluid buildup, or structural problems, conventional hearing aids may not be reliable or comfortable. Bone conduction hearing devices are often a more effective option in such scenarios as they steer clear of the problematic areas and transfer sound directly to the cochlea.

Bone Conduction Candidates

Bone conduction devices are beneficial for:

• Sound waves are not able to pass through the outer or middle ear, leading to conductive hearing loss.
• Chronic ear infections or drainage problems, where traditional hearing aids could worsen the condition.
• People with deformed ear canals or the absence of outer ears, who might not qualify for conventional devices.
• A condition called unilateral deafness, where a person experiences substantial or complete hearing loss in one ear. These devices provide a non-intrusive option that is frequently more comfortable, particularly for people, both young and old, who experience frequent ear issues.

Options that include implantable and non-implantable techniques:

There are two main types of bone conduction hearing devices:

• External non-implantable devices are usually secured using a headband, softband, or adhesive pad. They’re ideal for children, individuals trying bone conduction for the first time, or individuals not ready for surgery.
• Implantable (surgically placed): These devices include a small implant under the skin that connects to an external sound processor. They usually provide stronger performance and stability for long-term users. A professional assessment by an audiologist or ENT specialist will identify the most suitable solution for you, taking into account your age, individual anatomy, and personal hearing objectives.

Advantages of Employing Bone Conduction Hearing Devices

• Suitable for sensitive ears – does not necessitate insertion into the ear canal
• Good audio quality remains consistent, despite recurring problems with the ears
• Ideal for people with distinct physical characteristics – this alternative is particularly beneficial for people with congenital conditions impacting the outer ear or other anatomical variations.
• Enhanced communication– especially in school, work, or noisy environments

If you or your child struggles with hearing in one or both ears, particularly as a result of persistent infections or conductive issues, bone conduction hearing devices might be worth exploring.
