Answer 1

Exposure to loud noise.Head trauma.Virus or disease.Autoimmune inner ear disease.Hearing loss that runs in the family.

Answer 2

Deafness and hearing loss have many causes and can occur at any age. Conductive hearing loss occurs when something blocks sound waves from reaching the inner ear. Sensorineural hearing loss is caused by damage to the inner ear or to the nerves that send sound to the brain.

Many different conditions lead to partial and total deafness. Ear infections, fluid buildup behind the eardrum, holes in the eardrum, and problems with the middle ear bones can cause deafness from conductive hearing loss.

Tumours can also cause conductive hearing loss – they block sound from getting into the inner ear. Birth defects and diseases passed on by genes can do this, too.

Other causes of the hearing loss include Aging, circulatory problems, diseases such as diabetes, and long-term exposure to noise, slow decay of sensitive hair cells lining the inner ear makes recognizing of sounds difficult or impossible.
