Conductive Hearing Loss
Conductive hearing loss is when sound can't reach your inner ear. This can be caused by ear infections, fluid build up in your middle ear, something growing inside your ear canal, or Earwax pressing on the eardrum

Sensorineural Hearing Loss
Sensorineural hearing loss is when the cochlea or the auditory nerve aren't working. This can be caused by side effects of medicine, infections, high fevers, or can be genetic.
