Conductive Hearing Loss:- This hearing loss affects the passage of sound between the ear drum and the inner ear. Sound passes down the ear canal to the ear drum and through the middle ear, where the sound is transmitted across the middle ear by the three bones called the ossicles to the inner ear.

Causes of Conductive Hearing Loss:

1        Wax (cerumen):- A build-up of wax in the outer ear may stop sound from reaching the ear drum.
            2       Infection:- Infection and inflammation in the outer ear (otitis externa) or middle ear      (otitis media).
3      Glue ear (otitis media with effusion) :- Inflammation in the middle ear with associated fluid filling the middle ear     space around the ossicles. The fluid stops the ossicles and ear drum from moving effectively and stops sound from passing easily through to the inner ear.
4        Ear surgery :- May damage the ear drum or small bones in the middle ear stopping sound from passing easily through to the inner ear.


sensorineural hearing Loss:-The Sensorineural hearing loss is also known as SNHL, and occurs when inner ear nerves are damaged and cannot properly transmit signals to the brain.Dieases and Infection is the cause of sensorineural hearing loss.
