A conductive hearing loss occurs when the outer or middle ear does not efficiently transfer sound to the inner ear. In the outer ear common causes include ear wax and foreign objects in the ear canal.
conductive hearing loss is caused by damage to the bones of the ear,or to the tymanic membrane(eardrum),or to the outer ear. Nerve damage is the only other kind of hearing loss you can have and that is caused by damage to the nerves in the cochlea..I was born without eardrums and have a conductive loss
those that occur in the external and middle ear, are causes of conductive hearing loss.
Nerve conduction deafness is one of the two types of deafness that can happen. It occurs when there is a break in communication between the nerve cells and the inner ear.

One test used to determine conduction deafness is Weber's Test. A fork is vibrated against the forehead and should be heard equally in both ears. If it is heard best in the 'good' ear than it is sensorineural deafness but if it is heard best in the 'bad' ear then this is what determines the conduction deafness.

Conduction deafness can be a direct result of the fusion of any or all of the three ossicles of the middle ear. If the ossicles cannot transmit sound vibrations properly, then they will not be received by the oval window to be transmitted to the inner ear.
Saltatory conduction is made possible by myelinated nerve fibers. This is the means through which one node of Ranvier will communicate with the next.
When the bones of the ears are essentially stuck together, this is called auditory ossicle fusion or fixation. It is one of the many cause of Conduction Deafness or loss of hearing.
Fusion or fixation of the ossicles is where one or more of the three auditory ossicles cannot transmit sound vibrations for a variety of reasons. This does cause "conduction" deafness or hearing loss.
Demyelination is the process that erodes the sheath that normally protects nerve cells. This causes a reduction in the nerve impulse conduction. One of the diseases that causes this is multiple sclerosis.
That is one of dozens of possible causes.That is one of dozens of possible causes.
It is one of many possible causes.It is one of many possible causes.
Saltatory conduction is made possible by gaps in the myelin sheath (called nodes of Ranvier) along the axon, which allow for the action potential to "jump" from one node to the other, increasing conduction velocity.
