What are Implants of Listens?

hearing aid implants are medical devices that intensify sounds for people who are deaf who are implanted in the body instead of wore externally. Implanted devices are generally more expensive than externally worn hearing aids, but can be useful for people for whom conventional auditory aids are uncomfortable or unpleasant to wear or who suffer from forms of hearing loss that common auditory aids cannot effectively correct. Among the commonly used examples of the listeners are the implants of the middle ear and the hearing aids. The term is also used to indicate cochlear implants, although cochlear implants work on a very different principle from conventional hearing aids.

All hearing is based on the detection of vibrations in Kochle, structure in the inner ear. These vibrations stimulate sensory receptors in cochlea called hair cells that respond by producing electrical pulses that are sent to nerve cells and to the brain whereOnijsou interpreted and perceived as a sound. There are two types of hearing loss, sensorineural and conductive. Sensorineural hearing loss is the result of brain damage, vestibulocochlear or auditory, nerve or hair cells in cochle, the second is the most common cause. The conductive loss of hearing is caused by deformity, injury or obstacle that disrupts the lead of sound waves.

Heard aids anchored bones are the hearing aids that control the bones. The inner part of the device, a small titanium implant, is surgically implanted behind the ear. Then osseointegration begins, which is the process in which the titanium bonds with the bones of the skull. After several months, usually around three for adults and six for children, the gluing process is completed and an external sound processor is connected to the implant.

When the UDIO APROCESOR raises the sound, the sound is transmitted to the titanium implant. The implant vibrates and this vibrationis carried out with a skull to the inner ear. In people with normal hearing, these vibrations are directed to Kochlea through the outer and middle ear, but the vibrations can simulate it in the same way.

Hearing aids anchored bones are often useful for people with conductive loss of hearing because they completely circumvent the outer and middle ear. They are also useful for people who cannot wear conventional auditory aids due to infection or inflammation in the ear canal. In some cases, hearing aids are also used by people whose hearing is disrupted by only one ear, a condition called unilateral hearing loss, although they often have better results with a specialized external device called CR (contralateral signal routing) listening.

Middle ear implants are another type of hearing aid. The sounds are a picked up with an external microphone and the sound processor is behind the ear. Sounds are interpreted and converted to an electrical signal that is transmitted by the skin to the internalřně implantovaný přijímač. The receiver transmits this signal wire to a small converter implanted into the middle ear. This vibrates in response to the signal and these vibrations are performed in the inner ear and perceived as a sound.

cochlear implants are also often included in the category of hearing aids, although they work very differently and are in fact a substitute for hearing than to help. Like the middle ear implants, the cochlear implant has an external microphone that captures the sound. These sounds are analyzed by a speech processor that can distinguish speech from other sounds and filter out these other sounds. The processed sound is sent by a cable to an external transmitter that transmits the signal to the implanted receiver that sends electrodes to the kochlea electrodes.

Electricity is transmitted to the nerves in the cochle and then to the brain, where it is perceived as sounds. This does not renew normal hearing because many sounds are deliberately filtered and perception of the user's sound is PRSummed by a small number of electrodes rather than thousands of hair cells in cochle, but the user usually regains the ability to understand human language. Kochlear implants can be used by people who have a serious loss of hearing or are completely deaf if they still have a still functioning auditory nerve because they completely circumvent most of the normal auditory system and send information directly to the nervous system. These implants are usually ineffective for adults who have been deaf since childhood, because the ability of the brain to interpret sound during childhood usually does not develop unless they get any sounds to interpret.
