That's about the same level as a jackhammer ... but over 3 miles away.

How many bowls of cereal is a jackhammer when heard at 100ft?

You can't ask that kind of question without understanding the physics behind standardized measurements. What is the viscosity of the milk? i.e. whole milk or 2%? What is the relative humidity? Are the bowls glass or plastic?

The Cereal Experimentation Regulation Normalization board (CERN) has spent literally billons of dollars to analyze and study the sounds cereal makes and to standardize noise comparisons. At their cereal study facility in Switzerland they collide Rice Krispies at neatly the speed of light to calculate the noise they make.

Don't forget to include how many football fields the width of the bowl is.

My favorite cereal bowl is about 1/8 of a washing machine wide and holds enough to cover a football field with a micrometer of milk.

You're looking at about a decismoot, not football fields.

you joke, but NIST probably has a standard 'rice cereal' somewhere in their catalogue for testing

Are we gatekeeping sound questions now... this is ... cereal... errr... i mean surreal.

There's a simple formula for that. All weird units but it works out.

C=(3E/L)^O/D

C=Number of bowls

E=Height of the Empire State Building in smoots.

L=Information content of the Library of Congress in HD floppy discs

O=Orbital radius of Luna in yards

D=Distance to cereal in attoparsecs

I'm going to have to use this new unit of measurement.

This unit (equivalent at range X) is already widely used.

Not the rice bubbles part. :)

This seems odd to me. I know it was supposed to be loud, but I live about 14 miles from the launch pad and it didn't seem, by the very scientific measurement of my ears, to be any louder than any other launch, maybe even quieter.
