Master thesis

Master thesis at Ando Lab. @Univ. of Tokyo : Theory of effective sound transfer to basilar membrane and its application to an acoustic sensor

objective: understanding of the cochlea system, the improving of the sensitivity of the acoustic sensor mimicking a basilar membrane

  1. Investigate how to make the input impedance of the fishbone sensor mimicking the basilar membrane
  2. Match the sensor impedance and the impedance of the air with an exponential horn
  3. Confirm the increase of the output signal with the circuit
