I know I am a few chapters ahead but I thought this post was very educational. This video explains about the ear and how sound is transmitted. As you see in the video the sound passes through different parts of the ear but it is amazing how fast we may hear the sound. I pick this video because it break's down each part of the ear, also explains and shows sound waves as it passes through the ear. I enjoyed this video and learned from it. From watching this video I am ready to answer any question thrown my way.
