Check out the environmental recordings (I may have mentioned these but then again, I may not) section and listen to the 2nd 17 year cycada recording especially. In the first recording I was in Cherokee park (an Olmsted park) and it wasn't nearly as intense as I expected. In that one I was parked on a hill and a bicycle zooms past. In the 2nd recording I was in an open area with isolated big trees and it was incredibly loud. My truck was on the side of the road with the microphone set on the toolbox. At some point a car drives past. It gives you a good idea of how loud it was. In a wave editor the pattern looks just like a pop song: http://www.psychicreform.com/Music/index.htm
Once, a 1/4mile from the Wilcox playa (one cannot walk out onto/into the Wilcox playa), I was unable to hear any sound what-so-ever: the toad roar was so loud that my eardrums vibrated so rapidly that I could only hear the vibrations of my eardrums, and could hear nothing outside of my head! Wild! My estimate: 1/2 million individual toads. And I'm low-balling it. 4 species, including this one: http://www.bufoalvarius.org/images/Balvarius4.jpg seek
