Voice major Percussion major Brass major Woodwind major String major Keyboard major Percentage of students with MIHL 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 Then you get A $20 gift card!
