Reference sound intensity Io = 10^−12 W/m² (Threshold of human hearing).
Reference sound intensity level LIo = 0 dB-SIL (Threshold of human hearing intensity level).
Sound intensity is a sound energy quantity.
Our eardrums are moved by sound pressure variations. That is a sound field quantity.
Reference sound pressure po = 20 µPa = 2×10^−5 Pa (Threshold of human hearing).
Reference sound pressure level Lpo = 0 dB-SPL (Threshold of human sound pressure hearing level).

How is sound measured?
Hertz for pitch (high or low) and decibels (dB) for volume (loudness).
