STS-107 Space Shuttle launch from astronaut family viewing stands approximately 3 miles from launch pad. The low frequency sound waves were so powerful, you could feel your internal organs vibrate and the higher frequencies sounded like a loud crackle.  
The Krakatoa explosion was heard 3000 miles away. It ruptured eardrums 100 miles away.
