The cochlear implant is an electronic device that can provide a sense of sound to a person who is deaf or profoundly hard-of-hearing. This type of device is very different from a hearing aid, which serves only to amplify sound. A cochlear implant transforms sounds into electrical signals and transmits these signals directly to the auditory nerve of the inner ear, bypassing any damaged structures in the ear that are impeding normal hearing.
If you hear an annoying buzzing or ringing sound in one or both ears, you have tinnitus. It can bother you a lot. Tinnitus is a problem with your auditory system. That's the system that lets you hear. The problem may be in the ear. It may be in the nerve that connects your ear to your brain. Or, it may be in the part of your brain that makes sense of sound signals. Usually, tinnitus is not a sign that you have a serious issue.
This minimally-invasive surgical procedure is performed to help treat recurrent ear infections or a build-up of fluid in the middle ear. Small metal or plastic tubes are inserted into the eardrum to drain fluid and to allow air into the middle ear, equalizing pressure between the middle and outer ear. This procedure is most commonly performed on young children.
A hearing aid is a small device, worn on or in the ear, which amplifies sound and broadcasts it to the eardrum. Hearing aids are used to help those with hearing loss to listen and communicate more clearly. There are several types of hearing aids, and choosing the appropriate device can depend on comfort, size, performance and level of hearing loss.
