MEMPHIS, Tenn. (WMC) - Chirping crickets, usually fill the night along the countryside. While the chirping sound of male crickets are usually used to attract mates, scare off other males, or warn of danger, did you know it can also be used to help determine the temperature outside?
In this breakdown, we explain how you can determine the temperature just by listening to the simple chirp of a cricket.
Crickets do not use their legs to chirp. The iconic sound is by rubbing the edges of cricket’s wings together. The male cricket will rub a sharp ridge on the wind called a scraper against a series of wrinkles, also called flies, on the other wing.
The tone of the chirping mainly depends upon the disturbance between the wrinkles. So now we know how a cricket creates its chip, but how can it predict the temperature?
A cricket is a cold-blooded animal and the chemical reactions that allow it to chirp is determined by the temperature. In fact, you won’t hear a cricket chirp unless the outdoor temperature is at least 55 degrees fahrenheit and no warmer than 100 degrees.
To determine the temperature, just count the number of chirps that you hear in fourteen seconds and then add forty.
For example, you year 30 chirps in fourteen seconds, you then add 40 to that 30 and you get 70. So, the temperature should be around 70 degrees fahrenheit.
It is a good idea to repeat this process a couple of times to get a decent approximation or average. Usually the calculation is good within one degree and is mostly accurate 75 percent of the time.
That means the next time you are outside and hearing a cricket chirp, just know you can determine the temperature without even using a thermometer or your phone.
