Explain the difference between a conductive hearing loss and a sensorineural hearing loss in terms of the type of damage and the functional outcome
Fill in the blank(s) with the appropriate word(s).
ANSWER: A conductive hearing loss refers to any condition that impedes the sequence of vibrations or prevents them from reaching the auditory nerve, resulting in a loss in conduction. Sensorineural hearing losses are caused by defects of the inner ear or auditory nerve. Conductive hearing losses are seldom more than 60 to 70 dB. These losses can be effectively reduced through amplification, medical treatment, or surgery. Sensorineural losses can affect only certain frequencies, especially the high frequencies.
