Final answer:
Conductive hearing loss leads to partial loss of sensitivity due to problems with the transmission of sound through the outer and middle ear to the cochlea.
Step-by-step explanation:
The primary consequence of conductive hearing loss is partial loss of sensitivity. Conductive hearing loss occurs due to a problem in delivering sound energy to the cochlea, which can be caused by various issues such as blockage of the ear canal, a hole in the tympanic membrane, problems with the ossicles, or fluid in the space between the eardrum and cochlea.
The issue results in a reduced ability to hear sounds as they are not efficiently transmitted through the outer and middle ear structures to the inner ear. Devices like hearing aids can amplify incoming sound waves, aiding the vibration of the eardrum and movement of the ossicles, partly overcoming the hearing loss.
