Supersonic VS Subsonic Bullet Sound ASMR | Bullet Crack #asmr #cod #bullet

Published on May 2, 2024
Duration: 0:10

This demonstration, led by an experienced instructor, visually and audibly contrasts the acoustic signatures of supersonic and subsonic ammunition. The video highlights the distinct sonic crack produced by supersonic rounds fired from an AR-15, compared to the quieter report of subsonic rounds from a revolver. It serves as a practical illustration of ballistic acoustics for firearm enthusiasts.

Quick Summary

The 'sonic crack' from a bullet is an audible pressure wave created when a projectile travels faster than the speed of sound. Subsonic bullets, traveling below this speed, do not produce this crack, resulting in a quieter sound profile primarily from the muzzle blast.

Frequently Asked Questions

What causes the 'sonic crack' from a bullet?

The 'sonic crack' is an audible pressure wave created when a projectile travels faster than the speed of sound. This phenomenon is unique to supersonic ammunition and is a distinct acoustic signature.

How do subsonic bullets differ in sound from supersonic bullets?

Subsonic bullets travel below the speed of sound, so they do not produce a sonic crack. Their sound is primarily limited to the muzzle blast and the firearm's action, making them significantly quieter than supersonic rounds.

What firearms were used in the supersonic vs. subsonic sound demonstration?

The demonstration featured an AR-15 style semi-automatic rifle equipped with an EOTech holographic sight for the supersonic rounds, and a double-action revolver, likely a Smith & Wesson 686, for the subsonic rounds.
