Unformatted sample text from the term paper:
our population suffer from some degree of hearing loss. Hearing loss can result from a number of factors ranging from congenital birth defects to some sort of trauma to
disease. In the healthy individual hearing occurs with the passage of sound through the ear canal to the ear drum. The resulting vibrations are transmitted to the cochlea
and, in turn, electrical signals are passed on to the acoustic (auditory) nerve where they travel to the brain (Bowdler and Faulconbridge, 2003). Individuals with hearing loss experience a
disruption in one or more of these processes. Individuals who have encountered problems in the transmission of sound waves in the ear canal
and middle ear suffer from conductive hearing loss (Bowdler and Faulconbridge, 2003). Individuals who have encountered problems in the transmission of sound from the inner ear or at any
point in the passage of the sound signals to the brain suffer from sensorineural hearing loss (Bowdler and Faulconbridge, 2003). Conductive hearing loss, in general is more easily correctable
than is sensorineural hearing loss. The specifics of that correction, however, can vary substantially given that conductive hearing loss can result from a diversity of factors including:
"blockage by wax, infection, a collection of fluid, trauma or fixation of the ossicles in the middle
ear (eg otosclerosis)" (Bowdler and Faulconbridge, 2003). Fortunately, certain interventions can be implemented
in sensorineural hearing loss to give patients at least some semblance of normal hearing (Bowdler and Faulconbridge, 2003). For patients who are not aided sufficiently with exterior hearing aids,
