This video demonstrates the distinct sounds of supersonic rifle fire from 400 yards, differentiating between the sonic crack of projectiles passing and their impact. It uses an AR-15 and AK-47 to illustrate how sound travels and the audible effects at varying distances off target, providing a practical understanding of long-range ballistics. The content is presented by CajunBoyJake, a firearms enthusiast.

This episode of the Gunwerks podcast delves into the multifaceted benefits of shooting suppressed. Beyond the obvious hearing protection, suppressors reduce muzzle blast, prevent flinching in new shooters, and can even influence game animal behavior by altering sound propagation. The discussion emphasizes that 'hearing safe' is a complex metric and encourages a holistic approach to suppressor selection beyond just decibel ratings.

This video from Edwin Sarkissian explores the auditory experience of being shot at by various automatic weapons, including the M60, AK-47, and AR-15. Featuring insights from engineer Mark Serbu and designer Richie, the experiment focuses on recording the sound of incoming fire and impacts from behind reinforced concrete cover. The content highlights the importance of range safety and the distinct acoustic signatures of different calibers and firearms.

This video demonstrates the audible differences in bullet sounds at various distances, from 230 to 1000 yards. Garand Thumb, a recognized subject matter expert, explains ballistic acoustics using a variety of firearms and calibers. The experiment highlights the importance of range safety, including the use of defilade, and showcases how factors like distance, caliber, and suppressors affect the sound signature of a projectile.

This video demonstrates the acoustic phenomenon of supersonic bullets at long range. The shooter, CajunBoyJake, positions himself 450 yards from a steel target in a desert shooting range. The demonstration highlights the distinct sonic crack of the bullet passing the observer before the muzzle blast is heard, showcasing principles of supersonic ballistics and long-range shooting techniques.

This video from Administrative Results debunks the myth that the M1 Garand's distinctive 'ping' sound of an ejected en-bloc clip can betray a shooter's position. Through controlled testing at various distances, the channel demonstrates that the report of the firearm and its echo effectively mask the clip ejection sound, especially in a combat scenario. The expert assessment highlights the channel's historical context knowledge and structured field testing approach.
