What the Ear Throws Away (Chapter 5)
from Between the Signs: The Speech Communication Podcast
Hearing is not measurement. This episode follows sound through an ear that filters by direction, solves the problem of getting sound from air into liquid, and performs a frequency analysis mechanically, by letting a travelling wave peak at a different place for every frequency. Then the part that matters most for engineers: two tones of the same physical level are not equally loud, a quiet sound next to a loud one is simply not there at all, and the ear pools what it hears into a couple of dozen bands. Which leads to the sentence the next chapter depends on: what cannot be heard does not have to be transmitted. This episode was generated with artificial intelligence (NotebookLM) on the basis of the lecture script, and the voices are synthetic. In case of doubt, the lecture and the script are authoritative.
