AP PSYCHOLOGY

Detailed explanation-1: -Conductive hearing loss is due to problems with the ear canal, ear drum, or middle ear and its little bones (the malleus, incus, and stapes).

Detailed explanation-2: -Leading causes of conductive hearing loss include cerumen impaction, otitis media, and otosclerosis. Leading causes of sensorineural hearing loss include inherited disorders, noise exposure, and presbycusis.

Detailed explanation-3: -The middle ear consists of the tympanic membrane and the bony ossicles called the malleus, incus, and stapes. These three ossicles connect the tympanic membrane to the inner ear allowing for the transmission of sound waves.

Detailed explanation-4: -The contribution of the middle ear in bone conduction is usually associated with inertial response of the middle ear ossicles (Barany, 1938; Wever and Lawrence, 1954). The loose coupling between the ossicles and the head allows relative motion between the skull and the ossicles.
