Conductive hearing loss is a hearing impairment caused by some kind of obstruction on the way of sound from the outer ear to the inner ear. Such condition can in most cases be helped by medical or surgical methods.


Sensorineural hearing loss is connected with a disorder in the transformation of sound vibrations into electric impulses conducted to the patient’s brain. Such hearing impairments are more complicated and difficult to treat.
