What Makes a Cricket Chirp: The Science of Sound

Do you ever stop to listen to the sounds around you? The wind in the trees, the waves crashing on the shore, a baby laughing. All of these sounds are created by something called sound waves. Sound waves are created when an object makes some kind of noise, and they travel through the air until they hit something else and create another noise. 

Crickets are a type of insect that is known for their chirping noise. This noise is made by rubbing their wings together, and it can be quite loud! Depending on the species of cricket, they will chirp at different rates. Keep reading to learn everything you need to know about the world of crickets!

In this blog post, we will be talking about one specific type of sound wave- cricket chirps! We will explore what makes a cricket chirp and how long they typically chirp. We will also discuss what different cricket chirps mean, and how you can use this information to your advantage!

Cricket Chirp: How Do Crickets Make Sound?

What makes a cricket chirp? The sound of chirp is created by crickets rubbing their wings together, and it can really get your attention! The speed of the sound wave determines how high or low the pitch of the noise will be. Cricket chirps have a very high pitch because their wings move very quickly when they rub them together.

The frequency of chirping varies according to temperature. For example, the common house cricket will chirp more times than the snowy tree cricket per minute.

Back in 1897, the scientist Amos Dolbear publicized an article “The Cricket as a Thermometer” that emphasized the correlation between the ambient temperature and the speed at which crickets chirp.

Now that we know how cricket chirps are made, you might be wondering how long they typically chirp, and what chirping crickets mean. Crickets usually only chirp for a few seconds at a time, and then they take a break for a few seconds before starting up again.

What Do Chirping Crickets Mean

Before exploring the reasons behind cricket chirping, I want to share why crickets chirp in short bursts. The reason why crickets chirp in quick briefs is that it takes a lot of energy to rub their wings together quickly enough to create the sound wave. If they chirped for too long, they would get tired and wouldn’t be able to make the noise anymore. 

Now, let’s get to the root of this magical chirping sound. There are two main types of cricket chirps: calling and courtship. Calling chirps are made by male crickets in order to attract females. These calls can be heard from up to 100 feet away! Courtship chirps are made by both males and females during mating season. These chirps are much shorter than calling chirps and are usually only heard from a few feet away. 

Different types of cricket calls include:

– Calling Chirp: A long, continuous sound made by male crickets in order to attract females. Can be heard from up to 100 feet away. 

– Courtship Chirp: A short sound made by both males and females during mating season. Usually only heard from a few feet away.

– Stridulation: A continuous, high-pitched sound made by male crickets that are used to establish dominance over other males.

Now that you know all about what makes a cricket chirp, you can start using this information to your advantage!

How Long Do Crickets Chirp for

As we have explored the relationship between temperature and the pace of cricket chirping, now it’s time to get to the formula behind this connection! Dolbear’s law notes the association between the air temperature and the rate at which crickets chirp.

The chirping of the more familiar field crickets is not as reliably linked to temperature—their chirping rate alters depending on other elements such as age and mating success. In many cases, though, Dolbear’s formula is an accurate enough estimation for field crickets, too.

Most species chirp at higher speeds the warmer the temperature is (about 62 chirps a minute at 13 °C (55 °F) in one familiar species; each species has its unique rate)

Get To Know the World of Crickets

Now that you know all about cricket chirps, you can start to learn how to determine the type of cricket by paying attention to the sound and distance.

To determine the type of cricket based on audio:

– Listen for the length of the chirp. Calling chirps are long and continuous, while courtship chirps are shorter. 

– Listen for the pitch of the chirp. Calling chirps have a lower pitch than courtship chirps. 

– Determine how far away the cricket is. If you can hear the cricket from more than a few feet away, it is likely a calling cricket. 

If you want to attract crickets, make sure to mimic the sound of a calling cricket. You can also use cricket chirps to determine the temperature outside. The next time you hear a cricket, see if you can identify what type of call it is and why it is making that noise!
