The temperature is dropping at night and the crickets have been slowing down the speed of their chirps. Over the summer I came across a formula by A.E. Dolbear, published in 1897 which allows you to determine the approximate temperature based on the number of chirps a cricket makes in 15 seconds. To determine the temperature, (in Fahrenheit) count the number of chirps in a 15 second period and add 40.   Listen to the audio below.
