Typically, the idea of hearing aids invokes the idea of conventional devices that boost sound through the canal of the ear. But for individuals with specific kinds of hearing loss, particularly those dealing with persistent ear problems or single-sided deafness, a different kind of technology could provide better quality and comfort: bone conduction hearing devices.
The Functionality of Bone Conduction Hearing Devices
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 hub. This means that even when the ear canal is blocked or damaged, sound can still reach the auditory nerve. Think of it this way: If you’ve ever stopped up your ears and still been able to hear your voice when talking, that’s bone conduction.
Bone Conduction vs. Traditional Hearing Aids
Conventional hearing aids amplify sound and direct it through the ear canal. This strategy is particularly helpful for individuals who have had damage to the inner ear or the nerve in charge of transmitting sound, causing sensorineural hearing loss. On the other hand, if there are issues with the external or middle ear caused by infection, fluid accumulation, or structural problems, standard hearing aids may not work well or be comfortable. Bone conduction hearing devices are often a better option in these instances because they bypass the issue areas and send sound straight to your cochlea.
Bone Conduction Candidates
Situations where bone conduction devices are appropriate:
- Sound waves are unable to pass through the outer or middle ear, resulting in conductive hearing loss.
- Relentless ear infections or problems with fluid drainage could be aggravated by traditional hearing aids.
- People with malformed ear canals or missing outer ears, who may not be candidates for traditional devices.
- A condition called one-sided deafness, where a person experiences substantial or complete hearing loss in one ear. These devices offer a non-invasive option that is frequently more comfortable, especially for children and adults who have persisting ear issues.
Options that include implantable and non-implantable solutions:
There are two primary classifications of bone conduction choices: Implantable and non-implantable devices.
- Non-implantable (worn externally): These are usually kept in place with a headband, softband, or sticky pad. They are perfect for kids, those experimenting with bone conduction for the first time, or people who are not prepared for surgery.
- Surgically implanted devices involve a tiny device placed beneath the skin, which is connected to a separate sound processor mounted outside the body. They tend to offer more robust performance and reliability for long-term users. A professional evaluation by an audiologist or ENT specialist will identify the most appropriate option for you, considering your age, individual anatomy, and personal hearing objectives.
Perks of Employing Bone Conduction Hearing Devices
- Suitable for sensitive ears – does not necessitate insertion into the ear canal
- Clear sound quality, despite having persistent ear issues
- Perfect for individuals with distinct physical attributes – this option is particularly beneficial for individuals with congenital conditions affecting the outer ear or other anatomical variations.
- Improved communication is especially beneficial in instructional settings, professional environments, or noisy surroundings
If you or your child struggles with hearing in one or both ears, especially as a result of persistent infections or conductive issues, bone conduction hearing devices could be worth exploring.
