That brillant TED

Some observations from Julian Treasure about sound:
1.) You are a chord.
2.) One definition of health may be that that chord is in complete harmony.
3.) We see one octave; we hear ten.
4.) We adopt listening positions.
5.) Noise harms and even kills.
6.) Schizophonia is unhealthy.
7. Compressed music makes you tired.
8. Headphone abuse is creating deaf kids.
9. Natural sound and silence are good for you.
10. Sound can heal.
