Why was it originally invented and for what purpose?

# data[].attributes.body
It was originally invented by Professor Graeme Clark who wanted to help people like his father with profound deafness. Current hearing aids didn't help so he developed a multi-channeled implant.

The first model was created in 1978, which was a prototype for the first multichannel implant. It was later commercially distributed after alterations in 1982 with the Cochlear Nucleus 22.

Clark made the implants to help teens and adults with significant hearing loss who hearing aids did not benefit and who lost their hearing after learning language.

The most recent cochlear implant is the Cochlear Nucleus Nexa System. It contains its own firmware, similar to a smartphone, to enhance recipient sounds and give those using it more access to new innovations.

Very similar to the Nucleus 22 but it added a precurved electric array which is designed to position the electrodes closer to the auditory nerve. Its purpose is to deliver more focused and precise electrical stimulation to the nerves, which can lead to better hearing outcomes.

Digital signal processing - algorithms like SPEAK (spectral peak processing) and CIS (Continuous Interleaved Sampling allow for more precise decoding of sounds and more complex sounds.

Behind the Ear Implants - BTE implants allow the implant to become more compact and hidden.

Bluetooth - Bluetooth and wireless direct streaming of sounds from electronic devices allowed for better communication and ability to watch entertainment without need for other external medical devices.

Cochlear Implant control apps - Mobile apps on electronic devices to allow better control of volume adjustments and sound profiles.

Frequency range - extended frequency range that can enhance speech and music clarity.

Smarter sound processing - An automatic processing that reduces background noise and adjusts to being in loud or quiet settings.

AI - recent models allow AI sound processing to adjust automatically to the environment and reduce a cognitive load.

They added a sound processor that could be accessed through a remote control, for easier programming and control.
