# How is the wattage of a human larynx calculated?

This site says the typical human voice has a wattage of about 1W. Another site indicates it is 80db with about 0.001W of energy.

I'm confused. How does one compare 80db of 0.001W against 1W? Most importantly how is the wattage of the human larynx calculated?

There are many different decibel acoustic measures. It's hard to tell from those sites exactly which one they're using. If its the sound power level measure, then 80dB gives the power ratio relative to $10^{-12}W$, which would actually give 0.0001W, not 0.001W so maybe a typo?
