THE ROAR OF CICADAS.

THE ROAR OF CICADAS. An update from the Chicago Tribune on the seventeen-year cicadas in Chicago. There are three different species on the seventeen year cycle. The noise from their courtship songs can reach over 90 decibels (compared to the noise from a bulldozer). Exposure to 91 decibels for two hours “could begin to cause some permanent hearing damage.”
