Supersonic vs Subsonic

Published on August 10, 2023
Duration: 0:45

Hickok45 demonstrates the significant difference in sound signature between supersonic and subsonic ammunition when using a suppressor. Supersonic rounds produce a noticeable sonic crack, while subsonic rounds are much quieter, with the bullet impact being the primary audible event. For maximum suppression effectiveness, ammunition velocity should remain below the speed of sound.

Quick Summary

Subsonic ammunition is ideal for maximum quietness with a suppressor because it travels below the speed of sound, eliminating the sonic boom. This allows the suppressor to effectively reduce only the muzzle blast, resulting in a much quieter shooting experience where the bullet impact is the most prominent sound.

Frequently Asked Questions

What is the main difference between supersonic and subsonic ammunition when using a suppressor?

Supersonic ammunition travels faster than the speed of sound, creating a sonic boom ('crack') even with a suppressor. Subsonic ammunition travels below the speed of sound, eliminating the sonic boom and resulting in significantly quieter operation.

How does subsonic ammunition affect suppressor performance?

Subsonic ammunition allows a suppressor to perform at its maximum potential for noise reduction. Without the sonic boom from supersonic rounds, the primary sound heard is the bullet impacting the target, making the setup much quieter.

What suppressor is shown in the Hickok45 video comparing ammo types?

Hickok45 identifies the suppressor used in the demonstration as a Banish 30 Gold. This suppressor is designed for effective noise reduction, especially when paired with subsonic ammunition.

Why is subsonic ammo ideal for maximum quietness with a suppressor?

A suppressor is designed to reduce the sound of the gunshot's muzzle blast. However, supersonic ammo creates an additional, loud 'crack' from the sonic boom. Subsonic ammo avoids this boom, allowing the suppressor to effectively silence the muzzle blast alone.
