Is 9mm louder than 22?

22 caliber bullet is quieter than a 9mm, the most common firearm round. While a . 22 emits about 120 sound decibels, a 9mm produces up to 160 because a . 22 has smaller rounds than a 9mm.

Does 9mm hit harder than 45?

As we can see from the chart above, 9mm bullets have a higher muzzle velocity than 45 ACP bullets do. Combined with the 9mm's smaller size than . 45 ACP, that translates into deeper bullet penetration.

The 40 s&w round has higher pressures than the 9mm, and it generates around the same muzzle velocity than normal 9mm loads. You can find lighter 9mm rounds that have a 100 or 200 ft/per second advantage over most 40 caliber rounds, but that doesn't really mean that it offers superior ballistics.

Are bigger guns louder?

A small . 22-caliber rifle can produce noise around 140 dB, while big-bore rifles and pistols can produce sound over 175 dB. Firing guns in a place where sounds can reverberate, or bounce off walls and other structures, can make noises louder and increase the risk of hearing loss.

Even the most effective suppressors on the market, on the smallest and quietest calibers (. 22 LR) reduce the peak sound level of a gunshot to around 110 – 120 decibels.

What makes a gun louder?

A muzzle blast sound occurs because of the rapidly expanding propellant gasses that actually cause the bullet to accelerate; the gas expands extremely quickly, and the resulting pressure wave from that explosive expansion creates a whole lot of noise.

Can you silence a 9mm?

Yes, you can most definitely suppress a 9mm. While handgun and pistol suppression is less popular than say, suppressing a hunting rifle, it is still a great option. If you're using it for home defense, a pistol suppressor greatly reduces the deafening sound of a gun going off indoors.
