8. How loud is a 5.56 round?
A 5.56 round fired from an AR-15 produces a sound level of approximately 158.9 dB.
How loud is the AR-15
In general, a 16 inch AR-15 firing standard M193 produces a decibel level of around 167 dB give or take depending on environmental conditions. Averaging out a couple of the leading suppressors in the industry you see an average noise level of around 136 db with a suppressor attached. Which is a significant reduction.

Is an AR-15 louder than a 9mm
Assuming you meant an AR-15 chambered for the most common 5.56×45 cartridge, it is MUCH louder than a 9mm.
Why is an AR-15 so loud
It's the cartridge that makes the noise, not a particular firearm. The burn rate of the propellant powder and barrel length in which the cartridge is fired, are the biggest noise factors – Barrel length probably the most influential. Supersonic bullets also have a “sonic crack” as they break the sound barrier.
Is a AR-15 or ak47 louder
Is an AK-47 louder than an AR-15 The truth is, the range of measured decibels coming from these rounds is virtually the same. So the only real difference would come from the action. The bolt in the AR15 tends to not bang around as loudly as the ak platform… but compared to a gunshot, it's not that big a difference.

Is 5.56 louder than 9mm
The 5.56 rifle cartridge is inherently more powerful than the 9mm pistol cartridge, so you might expect the 5.56 to be a lot louder than the 9mm, but that's not the case. They're actually pretty close to one another. The 9mm cartridge averages about 166 decibels while the 5.56 cartridge averages about 169 decibels.
Which rifle has the loudest sound
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.
Which is more lethal 5.56 or 9mm
223 caliber (5.56 NATO) or the jacketed hollow point (JHP) in the 9mm. The ballistics and resulting wound trauma for each of these bullets reveals the 9mm provides much less terminal damage while remaining almost totally intact.

| M14 | 7.62x51mm (.308) | 159.0 |
| Colt AR-15 | 5.56x45mm (.223) | 158.9 |

They're actually pretty close to one another. The 9mm cartridge averages about 166 decibels while the 5.56 cartridge averages about 169 decibels.
Which bullet is the loudest

What does 120 decibels sound like
120 – 140 decibels: Such as, a rock concert, auto racing, or a hammer pounding a nail. 125 – 155 decibels: Like, firecrackers or fireworks, or a jet engine. 170 – 190 decibels: For example, a shot gun blast or a rocket lift off.
What is the quietest gun ever
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.
Is a 22 louder than a 9mm
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.
How many decibels is a scream
The average decibel level of human speech is estimated between 55 and 65 decibels. A whisper is considered the lowest decibel level of human speech. A whisper is between 20-30 dB. On the other hand, a human scream can reach decibel levels between 80 and 125 dB.
Why is 194 dB the loudest sound possible
At 194 dB, the energy in the sound waves starts distorting and they create a complete vacuum between themselves. The sound is no longer moving through the air, but is in fact pushing the air along with it, forming a pressurized wall of moving air.
Can you scream 1100 decibels
Most gunshots will register between 150 and 170 decibels. Hearing damage can happen very fast at these levels. It's a good idea to point out the proximity to our ears. No, 1100 decibels is not possible.
What is the quietest ammo
Set your 22 to stealth mode with CCI® Quiet-22™. It is ideal for bolt-action and single-shot 22 LR rifles, and generates 75 percent less perceived noise than standard velocity 22 LR rounds. It is perfect for areas where noise may be a problem and is ideal for introducing youth to the shooting sports.
How much louder is 556 vs 9mm
The 5.56 rifle cartridge is inherently more powerful than the 9mm pistol cartridge, so you might expect the 5.56 to be a lot louder than the 9mm, but that's not the case. They're actually pretty close to one another. The 9mm cartridge averages about 166 decibels while the 5.56 cartridge averages about 169 decibels.
How much dB is a gunshot
around 140 to 190 decibels
A gunshot is typically around 140 to 190 decibels. In comparison, a jet taking off is approximately 150 decibels. Decibels measure the intensity of sound.
Can a human survive 200 decibels
Sounds between 170-200 dB are so intense that they can cause lethal issues like pulmonary embolisms, pulmonary contusions, or even burst lungs.
What does 200 dB sound like
A sperm whale's click is 200 decibels, the unit used to measure the intensity of a sound, said Jennifer Miksis-Olds, associate professor of acoustics at Penn State.
What would 150 decibels do to a human
Any noise over 120 decibels, for any length of time, will cause hearing damage and elicit physical pain in your ear. Additionally, noises that register at 150 decibels will rupture a human eardrum.
Is 9mm quieter than 556
Noise Differences Between 9mm & 5.56
The 9mm cartridge averages about 166 decibels while the 5.56 cartridge averages about 169 decibels. Either way, that's still very loud and well above the threshold of 140 decibels for hearing damage.
Which bullets are 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 5.56 deadlier than 9mm
223 caliber (5.56 NATO) or the jacketed hollow point (JHP) in the 9mm. The ballistics and resulting wound trauma for each of these bullets reveals the 9mm provides much less terminal damage while remaining almost totally intact.
