Dear Alicia,

The clinical deafness may be caused due to impaired sound transmission in the external or middle ear is called conduction deafness.One of prior reasons for this deafness is the destruction of ear ossicles.Another common cause of conductive deafness is the failure of the eardrum to vibrate in response to sound waves.

Loud noises (such as gun shots, firecrackers, explosions and rock concerts) can also damage the delicate mechanisms inside the ear.

People also get conductive hearing loss when key parts of the ear - the eardrum, ear canal, or ossicles - are damaged. For example, a tear or hole in the eardrum can interfere with its ability to vibrate properly. Causes of this damage may include inserting an object such as a cotton swab too far into the ear, a sudden explosion or other loud noise, a sudden change in air pressure, a head injury, or repeated ear infections.

Thus there is no stereotyped reason for the damage to ear ossicles but it can be any of the above mentioned causes.

For the deatiled mechanism of hearing refer to the image attched with the reply.
