The flashcards below were created by user brianbauer78 on FreezingBlue Flashcards. What would you like to do?


  1. deafness
    Total hearing loss.
  2. otolaryngology
    Medical speciality associated with diagnosis and management of diseases of the ear, nose, and throat and related structures of the head and neck.
  3. audiologist
    A primary health care professional who evaluates, treats, and manages hearing loss and balance disorders in adults and children.
  4. conductive hearing loss
    A shift of the threshold of audibility due to mechanical impairment of any part or combination of parts of the ear.
  5. mixed hearing loss
    Hearing loss that includes both conductive and sensorineural impairments.
  6. sensory hearing loss
    Hearing loss from pathology involving the sensory end organ in the cochlea.  Most common sites include outer and inner hair cells within the Organ of Corti.
  7. neural hearing loss
    Hearing loss from pathology to the auditory branch of the Cranial Nerve VIII (8th nerve).
  8. sensorineural hearing loss
    Non-correctable hearing loss due to the damage, malformation or degeneration of a portion of the neural system in the ear.
  9. audiometric examination
    A general name given to hearing tests which include the charting of minimum threshold intensity, rating of wide frequency range in both ears, word perception, bone conduction and a visual inspection of the external ear.  Audiometric tests are usually given in a sound-treated chamber and take from one-half hour to three hours, depending upon the number and types of tests given.
  10. external otitis
    Inflammation of the outer ear.
  11. otitis media
    Inflammation of the middle ear.
  12. otosclerosis
    A disease in which bony growths inhibit the mechanical operation of the parts of the middle ear.
  13. tinnitus
    The medical term for the perception of sound in one or both ears or in the head when no external sound is present.
  14. temporary threshold shift
    Temporary hearing loss that is due to exposure to loud noises.  Sometimes called "acoustic trauma".
  15. pseudohypoacusis
    Hearing loss that is feigned or exaggerated.
  16. evoked potential
    Also known as "evoked response" is an electrical potential recorded from the nervous system of a human or other animal following presentation of a stimulus.  In this case, the stimulus is auditory.
  17. equalization
    Tailoring the audible frequency spectrum to particular intensity levels.  In this case, amplifying differentially those frequencies that audiological testing shows needs boosting.
