Live Stream of the 17-year Cicada Brood XIII from Glenview, IL (2024)
Peter Gena

N.B. Several factors influence the intensity of male chirping. The total population of cicadas should peak in mid-June. Activity increases with higher daily temperatures and rising sun, while precipitation and/or cooler air bring about a decrease or absence of chirping.

(In 2007, the din peaked at over 85db!  Documentation of the 2007 stream, including a WBEZ (NPR) radio program, a Chicago Tribune article, and sound samples can be found here: http://www.petergena.com/17yrcicada.html)
