Tests you will participate in
               Middle Ear Tests
   A tympanogram will determine the health
    and mobility your middle ear system
       Acoustic reflexes will examine the function of
        middle ear muscles
   If these results are not normal, you may be
    referred to the Student Health Center
      Test of Inner Ear Health
 For this test you will hear some tones at
  different pitches
 Results will tell us about the health of the
  organ of hearing in the inner ear
 This test may show damage from
  exposure to loud sound before a regular
  hearing test will
 Poor results mean you should be very
  sure to protect your hearing
              Hearing Test
 This will be the typical “raise your hand
  when you hear the beeps”
 This test will tell us if you have any hearing
  loss
 If you do, we may recommend that you get
  a full hearing test at an audiology clinic on
  campus or in your home town
            Genetic testing
 We will collect cheek cells by rubbing a
  swabbed stick inside each cheek
 These samples will be identified only by a
  numbered code
 We will analyze these samples for specific
  genes suspected of causing a
  susceptibility to noise-induced hearing loss
        DoseBadge exposure
          measurements
 Your last task will be to wear a doseBadge
  on your shoulder or on a hat for 2 school
  days
 This device will measure the loudness of
  your exposure all day long
 It will not record any sounds themselves,
  like your music or speech
