conduction deafness

…is heard longer by bone conduction than by air conduction, a conductive type of deafness is present. In the Schwabach test the presence of a sensorineural impairment is indicated when the individual being tested cannot hear the bone-conducted sound as long as the examiner with normal hearing can. The individual…

…to a problem with sound conduction, surgical restoration can correct the defect and restore hearing. When loss of hearing is the result of nerve damage, however, surgery is not of use. Medical treatment of auditory nerve damage is helpful only in rare cases—e.g., when the loss is due to syphilis…

…by the failure of sound conduction to reach the hearing nerve in the inner ear.

…simpler matter for listeners with hearing loss of the conductive type. Careful selection is necessary to ensure that maximum understanding of speech is obtainable in noisy environments. The hearing-impaired individual should consult with trained professionals such as audiologists, who are trained in evaluating the benefit derived from the use of…

A conductive hearing loss consists of damage to or obstruction of the outer or middle ear. A sensorineural hearing loss is caused by damage to the inner ear or the auditory nerve. A mixed hearing loss is diagnosed when an individual has both a conductive and…

…principal types of deafness are conduction deafness and nerve deafness. In conduction deafness, there is interruption of the sound vibrations in their passage from the outer world to the nerve cells in the inner ear. The obstacle may be earwax that blocks the external auditory channel, or stapes fixation, which…
