Bluetooth Technology for Cochlear Implants

A cochlear implant is an electronic device that is surgically implanted near the ear of a severely hearing-impaired individual. If you have a cochlear implant, you can now find compatible wireless Bluetooth adapters that let you hear your cellphone and other mobile devices. Several companies make Bluetooth adapters for cochlear implant users in a range of styles and colors.

  1. Cochlear Implants

    • For profoundly deaf people, cochlear implants restore a sense of sound using a tiny, but complex, electronic device. A microphone worn on the side of the head, similar in appearance to a traditional hearing aid, picks up sounds. The signal is handled by a speech processor, which filters and processes the signal before sending it to a transmitter. Under the skin, a receiver picks up the signal sent by the transmitter. The signal is sent to an electrode array surgically implanted deep within the inner ear, which stimulates the auditory nerve. This sends sound signals to the brain. A cochlear implant can't duplicate normal hearing, but it does allow users to hear sounds and understand speech.

    Bluetooth Technology

    • Bluetooth-enabled devices communicate with each other using shortwave radio signals. For example, a Bluetooth-enabled computer can send signals to a Bluetooth printer or speakers, while Bluetooth headsets enable cellphone users to make cordless hands-free calls. Unlike Wi-Fi, Bluetooth signals can only travel over short distances.

    Cochlear Implants and Bluetooth Technology

    • A Bluetooth adapter takes signals from your cellphone, laptop or other mobile device and relays them directly to the cochlear implant. They can also be used with listening systems. Headset adapters are much like the earpieces used by hearing individuals to make hands-free cellphone calls, fitting next to or over your implant's receiver. Neck-loop adapters hang around your neck like a pendant.

    Considerations

    • Bluetooth adapters for cochlear implants make cellphones easier to use. The same adapter can be used with any Bluetooth-equipped device. Because Bluetooth is a wireless technology, there are no awkward wires with which to contend. One drawback of Bluetooth adapters is that they can be expensive, especially when compared with other technologies.
