Is the M4/M16 louder than the AK-47 due to the higher gas pressure and because of the higher pitched sharper crack vs the lower pitch not as sharp crack of the AK-47? I was told that the 5.56X45 is slightly louder than the 7.62X39 but not by much. But other people tell me the AK is louder so dunno.

How much louder is the 7.62X51/.308 over the 5.56/.223/7.62X39? Is it by a lot or just by a little bit?

I heard the MK-19 is not that loud. But can it still damage your hearing or no?

How loud is the AT-4, the javelin and the RPG-7?

Which is louder, the 5.56X45 or 7.62X39?

Many people say the 5.56 is louder then the 7.62X39 dude to the much higher gas pressure(62,000 psi for 5.56 vs only 45,000 psi for 7.62×39) and that the bullet is almost 1000 ft per second faster. Is this true? I get mixed answers, some say the 5.56 is louder, others say the 7.62X39 is louder.

I know the 5.56 has a sharper sound while the 7.62X39 has more of a duller sound.

Also how does the 5.56X45 and 7.62X39 compare to the 7.62X51 NATO/.308 which has more powder?

Anyone who owns or fired both an AR-15/M4/M16 and an AK-47/SKS could help me?
