Crickets and Temperature

How to determine the temperature based on cricket chirping?

The sound that crickets make, “the chirp”, is due to the hard and rigid structure of on of the wings. When rubbed together they make the distinctive chirping sound we hear. Male crickets chirp for a number of reasons including to warn off predators as well as attracting their female counterparts.

Using a simple math equation we can determine the outside temperature while listening to the cricket chirp.

First, count the number of chirps your cricket makes in 15 seconds.

Now add 37 to the number of chirps above.

That’s it! You now have a good estimate of the temperature outside in Fahrenheit!

This formula is known as Dolbear’s Law. Which was also featured on The Big Bang Theory on season 3 episode 2 titled “The Jiminy Conjecture”.
