A. Causes of conductive hearing loss
All kinds of infections of the outer and middle ear, e.g. otitis, glue ears, a perforated drum. When too much fluid is produced so that a stick slime settles on the respective parts of the middle ear: the ear drum swells and bursts; the hammer and stirrup stiffen. thus there is no conduction of the sound wanes to the neural portion of the inner ear.
B. Causes of perceptive deafness (sensori-neural hearing loss)

B. Causes of perceptive deafness (sensori-neural hearing loss)
- Can be congenital (from birth).
- Negative influences during pregnancy, e.g. a viral infection of the mother: scarlet fever, influenza, some medicine like streptomicin.
- An accident whereby the inner ear (e.g. the perceptive canals) is severely injured.
