Decibel scale is exponential. 9mm comes in at 159.8 dB and 45 acp at 157 dB for a difference of 2.9 dB. Well every 3 dB is a factor of 2 in sound energy, so there really is a difference and 9mm is significantly louder.
Is 9mm or 45 Quieter?
They are both just as easy to suppress. It seems that 9mm with subsonic loads is quieter than . 45 when both are running dry with similar suppressors. Prices are in the same range for both.
Which ammo is the loudest?
Highest gunshot decibels by caliber (rifles):
- 7 mm Magnum – 166.5 dB.
- 30-06 caliber – 163.6 dB.
- 270 caliber – 161.9 dB.
- 243 caliber – 160.6 dB.
- 45-70 caliber – 160.1 dB.
- 50 caliber (black powder) – 159.7 dB.
Is 45 more effective than 9mm?
All things being equal, there is no difference in accuracy between the 9mm and 45 ACP. However, there is one caveat and that would be muzzle velocity. As the 9mm round fires a lighter bullet at a higher velocity, it will have less bullet drop over distance making it the better choice for long range shots.
How loud is a 45 caliber handgun?
A . 45 ACP pistol shot generates about 162 decibels, depending on the specific ammo and gun, and is well over the threshold for permanent hearing loss. Adding a suppressor reduces that sound output to about 133 decibels, below that threshold.

Recoil Energy
45 ACP recoil is nearly double that of the 9mm when launched from a similar pistol. Size and weight of the gun matter when calculating recoil. For example, a . 45 launched from a carbine will have less felt recoil than a 9mm shot from a subcompact CCW pistol.
What is the quietest firearm?
The De Lisle carbine or De Lisle Commando carbine was a British firearm used during World War II that was designed with an integrated suppressor. That, combined with its use of subsonic ammunition, made it extremely quiet in action, possibly one of the quietest firearms ever made.
How far away can you hear a 9mm?
A handgun shot can be heard about a mile away. At that distance, though, it might sound “almost like somebody tapping on a table,” Beisner says. In cities that deploy ShotSpotter, the company installs 20 to 25 sensors per square mile, to more accurately pinpoint the location of a shooter.
How loud is a pistol?
Firearms Are Loud
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.
Can a 9mm be silenced?
If you want a short 9mm silencer, consider the Banish 45 and use the shorter configuration. This allows you the benefits of a shorter ( around 6”) silencer on your gun, while still preserving the option to use it in a full-size configuration or on other guns.
Is 9mm suppressed?
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.
Do suppressors work?
So the short answer to the question: "How do gun silencers work?" is "Usually not very well!" Pistol silencers of a few centimetres diameter and a few tens of centimeters in length are both very limited in effect and prone to being blown off the end of the gun unless excellently well- fitted.

Are handguns louder than rifles?
Handguns can be louder than rifles because of the amount of energy and how it is released in relation to the shorter barrel. In rifles, most of the gun powder's energy is depleted by the time the bullet reaches the muzzle (sometimes) making the report less intense compared to an identical round fired in a handgun.
Is 45 better than 9mm for self defense?
Penetration and Expansion
Using a . 45 ACP might lessen the risk of bullets going through walls. Hence, it's a more preferred caliber for home defense. However, the 9mm may be more comfortable to use, but it might cause more damage indoors because of its penetration.
Is a 45 harder to shoot than a 9mm?
45s are generally a little heavier the felt recoil is fairly close, in as much as neither one is punishing at all. The 9mm is higher velocity, so it tends to be a little snappier.
