Ambient noise floor due to insects

Last time I wanted to measure a speaker it was fireworks season. Had to hope noting went off during a test.

As far as cicadas go I used to live somewhere where it always seemed to be the right season. The fun part was having a cat that would bring them inside in her mouth with them still alive and making the noise.
 
The loudest sounds made by living beings over here are probably human children screaming like crazy. They don't do that continuously, fortunately.
Human children produce a calibrated audio output in supermarkets on Saturdays.
They produce precisely one DWF of audio.
Think of the press and there volume in swimming pools and area in football pitches.
See if you can work out what DWF means.
