  17. History 2008 – Audiobone releases bone conduction headphones 1932 – Bekesy performs experiments on cats mid-1500s, Hieronymus Capivacci diagnoses hearing disorders 1880 – invention of Rhodes Audiphone 2 4 1 1550 – GirolamoCardano, sound transmitted to ear via rod held between teeth 1855 – Rinne develops tests to see if bone conduction would work better 1926 – Herzog and Krainz describe compressional bone conduction 2013 – Google glass implements bone conduction 1979 – Bone Fone is invented 1962 – Tonndorf, experiments on skull vibrations and cochlea 5 6 3 4http://www.audioboneheadphones.com/ 5http://www.tech.de/news/google-glass-wird-sozial-facebook-twitter-tumblr-und-evernote-zeigen-apps-fuer-datenbrille 6http://www.retrothing.com/2006/01/the_bone_fone_r.html 1http://www.kmle.co.kr/search.php?Search=Bekesy+audiometer&Page=1 2http://home.a01.itscom.net/tcoh/audiphone.jpg 3http://hearinghealthmatters.org/waynesworld/2012/the-origins-of-bone-conduction-hearing/

  18. My Work • Created a mathematical model to simulate bone conduction on the cochlea • Looked at: • Wave propagation in cochlea • Vibration of basilar membrane • Fluid motion in the cochlea

  19. Research Process • Fundamental Laws of Physics • Conservation of Momentum • Conservation of Mass • Apply physical properties • Viscosity, compressibility, amplitude, pressure difference in cochlea, stiffness of basilar membrane

  20. Some Results • Velocity of basilar membrane at different frequencies
