Healthwise Inc., 1992. Blindness and Visual Impairment in Canada . Conductive hearing loss results from the blockage or interference of sound to the inner ear. People with conductive hearing loss often complain that their own voice sounds loud while other voices sound muffled. There may be a low level of tinnitus or ringing in the ear.
Most hearing loss is sensorineural.
This means that it is caused by problems of the nervous system in the inner ear. People with sensorineural hearing loss generally do not suffer from total deafness. They may have trouble understanding the speech of others while being very sensitive to loud sounds. The person may hear clicking, ringing or hissing noises. The loss occurs bilaterally and symmetrically.
