Laboratory Introduction
We are working to elucidate the auditory mechanism from microwave engineering point of view. Though we all are amateurs in the field of medicine, students have a strong spirit of challenge for this research.
- Title
- * Study on Mechanics of Human Auditory System From Microwave Engineers' Point of View
- Highlight
-
Considering the auditory mechanism from microwave engineers' point of view, we notice that
(1) the auditory system operates based on the even-odd mode theory,
(2) the sounds are detected by differential mechanism, and
(3) simulations should be done in accordance with the distribution constant theory.
Let's argue with us.
