hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea
A
frequency theory
B
conduction hearing loss
C
sensorieneural hearing loss
D
cochlear implant
Explanation: 

Detailed explanation-1: -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-2: -Conduction Hearing Loss: Hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea. Sensorineural Hearing Loss: Hearing loss caused by damage to the cochlea’s receptor cells or to the auditory nerve, also called nerve deafness.

Detailed explanation-3: -Conductive hearing loss (CHL) occurs because of a mechanical problem in the outer or middle ear. This may be because: Sound is not reaching the eardrum. The eardrum is not vibrating in response to sound.

Detailed explanation-4: -Sensorineural (sen-sory-nuhral) hearing loss occurs when there is a problem with the sensory receptors of the hearing system, specifically in the cochlea of the inner ear. The majority of sensorineural hearing loss occurs as a result of an abnormality or damage to the hair cells in the cochlea.

Detailed explanation-5: -The eardrum is a tight membrane, and when sound waves hit it, it vibrates. Right after hitting the eardrum, three bones in the middle ear (hammer, anvil, stirrup) pick up the vibrations and transmits them to the cochlea.
