This is a guess, but the skull itself and surrounding tissue would presumably conduct sound/vibration even if the conductive mechanism in the ear was not working. I was quite young when I had tests but I seem to remember someone pressing something (might have been a tuning fork?) to the bony bit behind my ear to see if I could hear the tone...

Other causes include problems with the hair cells in the Cochlea (hair cells sense sound vibration and translate the vibration into a neural signal), and problems in the hearing centers in the brain itself. Conductive hearing loss is when there is an injury to the outer ear - the tympanic membrane (eardrum) or the three bones that connect the eardrum to the Cochlea, the inner ear is infected or filled with fluid, the ear is plugged up with earwax... all of these are mechanical problems that either prevent sound vibrations from causing the inner ear to vibrate or prevent the sound vibrations from getting to the inner ear in the first place. Many of these problems can be repaired surgically or with a thorough cleaning of the ear canal. Check out Wikipedia for the descriptions and an anatomical drawing.
