Typically, the concept of hearing aids conjures up the idea of conventional devices that raise the volume of sound through the canal of the ear. But for people with specific kinds of hearing loss, particularly those dealing with chronic ear issues or single-sided deafness, a distinct kind of technology could offer better quality and comfort: bone conduction hearing devices.
How Bone Conduction Hearing Devices Work
Bone conduction hearing devices function by bypassing the outer and middle ear. Rather than relying on airwaves to transmit sound, these devices use the head’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 blocked or damaged, sound can still reach the auditory nerve. Think about this example: When you put your hands over your ears and are still able to hear the sound of your own voice while talking, that’s an example of bone conduction working.
Bone Conduction vs. Conventional Hearing Aids
Standard hearing aids increase sound and direct it into the ear canal. This strategy is particularly helpful for individuals who have experienced damage to the inner ear or the nerve in charge of transferring sound, resulting in sensorineural hearing loss. However, if there are issues with the outer or middle ear dued to infection, fluid collection, or structural problems, conventional hearing aids may not work well or be comfortable. Bone conduction hearing devices can be a more reliable option in such situations as they steer clear of the problematic regions and transfer sound directly to the cochlea.
Best Candidates For Bone Conduction
Bone conduction devices are beneficial for:
- Sound waves are not able to travel through the outer or middle ear, leading to conductive hearing loss.
- Persistent ear infections or drainage problems, where traditional hearing aids could worsen the condition.
- People with malformed ear canals or missing outer ears, who may not be candidates for traditional devices.
- Single-sided deafness (SSD), where one ear has profound hearing loss or no hearing. These devices provide a non-intrusive option that is typically more comfortable, particularly for individuals, both young and old, who experience recurring ear problems.
Implantable vs. Non-Implantable Options:
There are two main types of bone conduction hearing devices:
- Non-implantable (worn externally): These are usually kept in place with 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 installed): These devices include a small implant under the skin that connects to an external sound processor. Long-term users often find that they supply more effective and dependable results. A professional evaluation by an audiologist or ENT specialist will determine the most suitable option for you, taking into account your age, particular anatomy, and personal hearing objectives.
Perks of Using Bone Conduction Hearing Devices
- Suitable for sensitive ears – does not require insertion into the ear canal
- Good audio quality remains consistent, despite recurring problems with the ears
- Ideal for individuals with distinct physical characteristics – this alternative is especially beneficial for people with congenital conditions affecting the outer ear or other anatomical variations.
- Improved communication is especially advantageous in educational settings, professional environments, or noisy surroundings
If you or your child copes with hearing in one or both ears, particularly due to persistent infections or conductive problems, bone conduction hearing devices might be worth exploring.
