In the lecture, the speaker talks about flappy and spiky sound receptors in ears. At the beginning of the lecture, the speaker says that the sound receptor can translate vibrational energy of the sound in the eardrum. Also, the speaker mentions that the sound receptor can help to transfer vibrational energy into a physical motion, electrical motion and then convert it into an electrical signal. According to the speaker, these things are pretty impressive, however more details will not be discussed. Lastly, the speaker indicates that MIT students have more opportunities to have a closer look.
