Document Summary
Chapter 10: how do we hear, speak, and make music. Music plays a role in our social and emotional lives as does language. Modern human brain: can analyze music in right temporal lobe (complemented by specialization for analyzing aspects of speech in the left temporal lobe) Neanderthals + homo sapiens probably coexisted together (resemble each other: neanderthals probably have large brains compared to homo. Neanderthals however probably had poor language ability because of skeletal analyses of the larynx. Music and language allow us to interact socially. Sound wave: undulating (move with smooth wave like motion) displacement of molecules caused by changing pressure: can move through air, water, even the ground. Experience of sound is a creation by human brain. Does a tree that falls in the forest make a sound if no one is there to hear it? : no! A falling tree hitting the ground makes sound waves not sound. Sound is mechanical energy that we hear.
