Big Picture Science - Sounds Abound
The world is a noisy place. But now we have a better idea what the fuss is about. Not only can we record sound, but our computers allow us to analyze it.

Plus, native Ohio speakers help decipher what Neil Armstrong really said on that famous day. And, think your collection of 45 rpm records is impressive? Try feasting your ears on sound recorded before the Civil War.
