Hearing aids are small hearing devices that increase the volumes of certain sounds. There are many different types of them, but these are the most common: behind the ear, in the ear, in the canal. Hearing aids are good because they can increase sounds of certain things rather then increasing the volume of everything.

Cochlear Implants are hearing devices that are mostly worn behind the ear. To use them, you must first undergo a surgical operation to provide electrical signals to your cochlear. To use these signals, the surgeon slides a wire that has around a dozen or a few dozen electrodes. These electrodes interpret the signals, then send them directly to your brain. Cochlear implants are usually for people who have severe to profound hearing loss. If you get cochlear implants earlier, you will probably have better hearing and language skills.

The most common bone conduction hearing aid is a BAHA, which you use for outer and or middle ear disfunction. The BAHA is for moderate hearing loss, and it is located in the bone behind the ear. The way it works, is it captures sound waves and vibrates the bone to transfer signals directly to the cochlear.
