How Loud Stuff Is

dB – sound is measured in decibels

Interesting:

– buildings can crumble using sound.  There’s a theory, that that’s how the Egyptians cut stone so perfectly (a dollar bill can’t fit between the pyramid stones)

– the threshold of pain is 120 dB

– below is a box of $20 headphones.

Hearing doesn’t grow back, eh.
