5. Tests you will participate in

6. 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

9. 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

10. 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
