Acochlear implant would be most for those who suffer

sensorineural hearing loss

Explanation:

The sensorineural hearing loss was called "nerve deafness."

The treatment of sensorineural hearing loss varies depending on the severity of the hearing loss and whether you suffer from it in one or both ears.

Hearing aids can help most people with mild to moderate sensorineural hearing loss in one or both ears.

Another solution, if the patient hears well or has mild hearing loss in his good ear, a cohclear implant is a good solution.

fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges. the core principle of fluid balance is that the amount of water lost from the body must equal the amount of water taken in.
