Implantable Hearing Aids

Hearing aids are devices that assist in providing a better quality of sound. These devices amplify the sound, which is then transmitted through the ear in the form of vibrations. Over the past few decades, a number of methods have been developed to overcome hearing loss. With the rapid advancement in technology, hearing aids have undergone a sea change. In recent years, implantable hearing aids have become a preferred option for the treatment of severe hearing loss. Even those with moderate hearing impairment are advised the use of such devices for better communication. Also known as 'internal hearing aids', these devices are totally invisible to the naked eye. They are a better alternative to conventional hearing aid amplifiers. A surgical procedure is used to implant the device through an incision behind the ear.

Implanted hearing aids can be placed surgically or through non-surgical methods. Surgically implanted devices are costlier. Cochlear implants are hearing aids that provide sound recognition using an electrode, that is implanted surgically into the cochlea. People suffering from profound hearing loss are advised such devices. Based on the degree of hearing loss, it is determined whether the person is eligible for cochlear implants. Cochlear implants use electricity to stimulate the nerves that are situated in the auditory system. People with certain levels of hearing may be rejected for this procedure. An important point to note, is that people who have received cochlear implants can switch off their devices, when not required.

Auditory brainstem implants are recommended for people whose auditory nerves are removed. As the name suggests, the device is directly implanted in the brainstem. Cochlear implants or other hearing aids, are not beneficial for such people, and hence using auditory brainstem implants is a better option.

Advantages of Using Implantable Hearing Aids

Implantable hearing aids provide sound which is much more natural and clearer than traditional hearing aids. One more benefit of using these devices is that they do not require frequent battery replacements. On the other hand, users of conventional hearing aids have to replace batteries from time to time. A special remote control is used for controlling various aspects of the device which is quite convenient for the user. That means, one can make changes such as volume control adjustments, without touching the device.

People who use implantable hearing aids experience better sound quality and improved speech intelligibility. These people are now able to distinguish between sounds and noise. These devices are lightweight and increase the quality of life. Conventional hearing aids are not practical for people leading an active lifestyle. Also, these devices are inadequate for severe hearing loss. Implantable hearing devices cannot be seen as they reside beneath the skin. They give the freedom to perform normal activities such as swimming and showering, which is not possible with traditional hearing devices.

Implantable hearing aids are a boon for people suffering from acute deafness. With the help of these devices, deaf people are now able to lead a full and productive life.
