In conduction deafness, sound vibrations cannot travel from the external ear to the internal ear. Knowing the pathway of sound through the ear, which of these could cause conduction deafness?

Question

Conduction deafness is caused by any condition that interferes with the transmission of sound vibrations through the external and middle ear. Damage to the tympanic membrane can prevent sound from reaching the ossicles of the middle ear, leading to conduction deafness. Loss of otoliths in the utricle and saccule would result in balance problems but not necessarily affect hearing. Loss of hair cells in the cochlea or damage to the spiral organ would result in sensorineural deafness, not conduction deafness.
