"Hearing" - the conversion of sound into nerve impulses - occurs in the inner ear. The outer and middle are concerned with changing pressure waves in air into pressure waves in a liquid.
The outer ear, consisting of the earlobe and ear canal, has no direct role in hearing. Its main function is to collect sound waves from the environment and channel them towards the middle and inner ear where the process of hearing takes place.
Well, ear defenders will sit over your whole ear protecting all of it. But the part that's important to protect is the inner ear, that's where the actual hearing takes place.

Cochlea is the part of inner ear, which detects sound waves.
The part of the human ear that plays no role in hearing is the outer ear, specifically the pinna (or auricle). The pinna's primary function is to help direct sound waves into the ear canal, but it does not participate in the actual process of hearing. The actual hearing occurs in the middle and inner ear, where sound vibrations are converted into neural signals.

The most visible part of the ear is called the outer ear wich sticks out where other people can see it.
Open fit ear hearing aids are extremely small and nearly invisible to an observer. Essentially, open ear hearing aids are small units that sit up on top of and behind your ear. here is no earmold to occlude the ear canal when open fit hearing aids are worn - the clear tube is extremely thin and leaves the canal open. The biggest benefit to open fit digital hearing aids is that they minimize occlusion. Open ear hearing aids sit up high on your ear and are placed in the back of your ears. They do not block the ear canal, contrary to traditional hearing aids.
