Explain why, even next to a complete conductive audible range loss?
the hearing threshold shift is limited to about 55dB. hence suggest a method to distinguish between conductive and sensorineural audible range loss?
Answers:
I also have sensorineural hearing loss in my right ear! This is a guess, but the skull itself and surrounding tissue would presumably conduct sound/vibration even if the conductive appliance in the ear was not working. I be quite young when I had test but I seem to remember someone pressing something (might have been a tuning fork?) to the bony bit losing my ear to see if I could hear the tone...
I have sensorineural hearing loss in my right ear - the cranial gall that connects my brain to my ear was damaged in an coincidence years ago and I cannot hear anything out of that ear, it cannot be surgically repaired, and will never heal on its own, so it is permanently deaf. Other causes include problems near the hair cells in the Cochlea (hair cell sense sound vibration and translate the vibration into a neural signal), and problems surrounded by the hearing centers in the brain itself.
Conductive hearing loss is when within 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... adjectives of these are mechanical problems that either prevent sound vibrations from cause 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 next to a thorough cleaning of the ear canal. Check out Wikipedia for the descriptions and an anatomical drawing.
