This means the pellet will become unstable and unpredictable at certain speeds. An airgun pellet is considerably smaller so while it creates less disturbance in the air, the impacts are felt with more intensity. A larger object passing through the sound barrier experiences turbulence and vibrations causing it to become somewhat unstable. While you can break the sound barrier with an airgun capable of reaching these FPS standards, there is a bit more to it.

It is even easier to tell if the pellet is breaking the sound barrier when you use a silencer at the muzzle so the only crack you hear is the pellet breaking the barrier rather than any added noise from the gun itself. You will know if your pellet broke the sound barrier because there will be a sustained crack when you fire that isn’t attributed to the muzzle blast. The speed of sound is influenced by outside factors such as elevation, air pressure, and air temperature. The sound barrier is usually broken anywhere between 1,060 to 1,200 feet per second, depending on the conditions. When looking at the matter of sound barrier FPS, you are looking at an airgun capable of achieving anywhere from 1,000 to 1,600 feet per second at the maximum. Now that we understand how the sound barrier works and why it matters, let’s look at it from an airgun perspective. While it is possible to break the barrier of sound, it doesn’t mean it is always safe or advisable. If an object is transonic and merely approaches the barrier without surpassing it, the object will become increasingly unstable from the pressure waves and vibrations. If an object surpasses the speed of sound, these pressures are minimized and the object passes through without as much instability. An object approaching the speed of sound creates pressure in the air waves in front of the object and creates a significant level of instability. The second thing to keep in mind is that when an object travels past the sound barrier the object is often impacted by it. For starters, the speed of sound is measured in meters whereas an airgun measures the distance traveled in feet so there is the difference of conversion. When looking at the sound barrier FPS factor for airgun purposes, there are a few things to keep in mind. Transonic is below the 343 meters per second average. When an item comes close to reaching the speed of sound, it is called transonic.

This is rare and usually only attained in experiments or studies. When an item exceeds the sound barrier by at least 5 times the speed, it is called hypersonic. When an object breaks the sound barrier (travels faster than the speed of sound which is usually around 343 meters per second, depending on air and elevation factors), it is called supersonic. Breaking the sound barrier simply means an object travels faster than the speed of sound creating shock waves and usually a loud boom sound.

It was an accident, but it opened up a world of curiosity about how the sound barrier worked and how to break it with a manned aircraft.

In the 1940s, breaking the sound barrier was a big deal because a manned aircraft had never done so until a couple of World War II pilots were trying to test fighter planes and broke the sound barrier in the process.

While breaking the sound barrier was once a pretty big deal, today it isn’t a big topic of discussion. The sound barrier isn’t something most people think about all that much in modern times. What is the sound barrier and how is it broken? When it comes to the sound barrier and FPS, there is a common misconception among beginning airgunners that you should aim for an option capable of breaking the sound barrier, but there is more to it than that. A lot of airgun enthusiasts choose their gun based on the FPS as a marker of performance. There has been a lot of talk about the sound barrier FPS (feet per second) in the airgunning community lately. While it is something airgunners talk about, there are a few misconceptions about what it really means and why breaking the barrier may not actually be worth it. Reaching or surpassing the sound barrier with an airgun is fun and gives bragging rights.
