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. For individuals struggling with specific hearing impairments, including relentless ear problems or unilateral deafness, an alternative option may supply improved sound quality and user comfort: bone conduction hearing aids.
How Bone Conduction Hearing Devices Work
Bone conduction hearing devices function by bypassing the outer and middle ear. Rather than sending sound through the air, they transfer vibrations through the bones of the head to the inner ear (cochlea), where the sound is processed. This allows sound to reach the auditory nerve even if there is an obstruction or injury in the ear canal. Consider 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 illustration of bone conduction working.
Comparison between Bone Conduction and Traditional Hearing Aids
Traditional hearing aids amplify sound and funnel it through the ear canal. This works effectively for people with sensorineural hearing loss, where the inner ear or auditory nerve is compromised. On the other hand, if there are problems with the outer or middle ear caused by infection, fluid accumulation, or structural concerns, standard hearing aids might not work well or be comfortable. Bone conduction hearing devices are typically a better option in these cases because they skip over the problem areas and send sound directly to your cochlea.
Best Candidates For Bone Conduction
Bone conduction devices are helpful for:
- Conductive hearing loss, when sound has difficulty traveling through the outer or middle ear at all.
- Chronic ear infections or drainage issues, where traditional hearing aids could worsen the condition.
- Individuals with deformed ear canals or the absence of outer ears, who might not qualify for traditional devices.
- Single-sided deafness (SSD), where one ear has severe hearing loss or no hearing. These devices provide a non-invasive alternative that is often more comfortable, particularly for kids and adults with recurring ear issues.
Implantable vs. Non-Implantable Options:
There are two primary categories of bone conduction choices: Implantable and non-implantable devices.
- Non-implantable (worn externally): These are usually held in place with a headband, softband, or adhesive pad. They are excellent for kids, people trying out bone conduction for the first time, or people who are not prepared for surgery.
- Implantable (surgically installed): These devices consist of a small implant under the skin that connects to an external sound processor. They usually provide more robust performance and stability for long-term users. A professional evaluation by an audiologist or ENT specialist will determine the most appropriate solution for you, considering your age, particular anatomy, and personal hearing objectives.
Perks of Employing Bone Conduction Hearing Devices
- Ideal for sensitive ears – does not necessitate insertion into the ear canal
- Great audio quality remains consistent, despite recurring issues with the ears
- Ideal for those with distinct physical characteristics – this alternative is especially beneficial for individuals with congenital conditions impacting the outer ear or other anatomical variations.
- Enhanced communication is particularly beneficial in educational settings, professional environments, or loud surroundings
If you or your child copes with hearing in one or both ears, especially due to chronic infections or conductive issues, bone conduction hearing devices could be worth exploring.
