decreased bone conduction in an audiogram indicates which of the following ____
A
glue ear
B
tympanic membrane perforation
C
damage to cochlea
D
ossicular dislocation
Explanation: 

Detailed explanation-1: -Type of loss If the hearing thresholds obtained by bone conduction are the same as the air thresholds, this indicates no blockage in the outer or middle ear. The hearing loss would be caused by a loss of sensitivity in the cochlea or hearing nerve. This is called a sensorineural hearing loss.

Detailed explanation-2: -Sensorineural Hearing Loss This type of hearing loss occurs when the inner ear or the actual hearing nerve itself becomes damaged. This loss generally occurs when some of the hair cells within the cochlea are damaged. Sensorineural loss is the most common type of hearing loss.

Detailed explanation-3: -Conductive hearing loss results when there is any problem in delivering sound energy to your cochlea, the hearing part in the inner ear.

Detailed explanation-4: -Conductive hearing loss can be produced by any defect in the pinna, external auditory canal, tympanic membrane, and ossicles, up to the footplate of the stapes.
