Hearing Things

In lesson 5 we look at sound, the ear and how the brain hears pitch, timbre and spatial locations of sound sources.

Preparation before the lecture:

  1. Watch "Basics Of Auditory System Crash Course"

    This video comes from the "CrashCourse" youtube channel. Note: He talks VERY FAST. You can slow down the play back speed if needed.

    Also note: the lecturer over-simplifies the notion of pitch. We will talk about more interesting aspects of pitch in class.
