Why are Biathlon Rifles So Quiet? The Athletes Don't Even Wear Ear Protection
In biathlon, a winter sport that combines cross-country skiing and rifle shooting, athletes use specialized rifles that are remarkably quiet. This unique feature allows competitors to shoot without wearing ear protection, even in indoor venues.
The lack of noise generated by biathlon rifles is attributed to several factors:
Subsonic Ammunition: Biathlon rifles fire subsonic ammunition, meaning the bullet travels slower than the speed of sound. This reduces the shockwave created when the bullet exits the barrel, resulting in less noise.
Integral Suppressors: Most biathlon rifles are equipped with integral suppressors. These devices trap and dissipate the expanding gases released when the bullet is fired, further reducing noise levels.
Low-Muzzle Velocity: The muzzle velocity of a biathlon rifle is significantly lower than that of a typical firearm. This results in less noise generation at the point of firing.
Encapsulated Barrel and Action: Biathlon rifles feature an encapsulated barrel and action, which helps to contain the sound waves produced when the bullet is discharged.
Training and Technique: Biathlon athletes undergo extensive training to develop proper shooting techniques that minimize noise, such as holding the rifle firmly and using smooth trigger control.
