Outline Activities
My research focuses on the mechanical vibrations in the auditory peripheral system induced by sound waves. Since these mechanical vibrations are correlated with sound perception, I aim to clarify how we hear sound from the perspective of the auditory peripheral system. My research methods include numerical simulations, non-invasive physiological experiments, and perceptual experiments. I am also interested in the engineering applications of the findings obtained through these studies.
Research Interests
  • A study of auditory information processing mechanism and its engineering application
    keyword : Auditory peripheral system, numerical simulation, nonlinear phenomena
