I have a Mini-30 model 5854 GBCPC "Tactical" version of ~ 2011 vintage (ser. no. 581-94XXX), and I got complaints from fellow shooters and bystanders beside and slightly behind me on the firing line at a recent shooting outing in open air, in a farm field. They said "Dang, that rifle is LOUD!"
I also have an older model stainless woody Mini-30 with straight muzzle, and I never got such complaints. It's louder than a .22LR by far but a "tame" rifle, most people think. (Same ammo mix as for the GBCPC tactical shoot.)
The main difference I can identify between the two rifles is the flash hider on the GBCPC Tactical (well, the barrel is 4" shorter, too, but I can't see that making much difference).
Are we dreaming? Does the flash hider make the muzzle report louder to those to the side or behind the rifle? As the shooter, I did not notice excessive loudness (but, of course, I was wearing ear protection and focusing on shooting). What is your experience or knowledge?
I did do a little homework on this forum. This exchange was related:
Flash hider/suppressor; yay or nay, in case you wanted to get the full context and "drift".
Theoretically, I agree with Mr. Snuffalupagus that the total acoustic energy liberated by the shot has to stay the same with or without the FH, but the sonic energy of the muzzle blast could be re-directed. However, with no flash hider, the acoustic energy of the muzzle over-pressure can go anywhere and everywhere, including side-ward and backward. Looking at the GBCPC's flash hider, I see no particular reason that the blast energy would be reduced to the front and increased to the side or rear. All that energy can go to the side or rear without the flash hider if it wants to - there's nothing stopping it. Please explain....

If you shoot a lot, it helps to keep the muzzle rise down and target in site. It does make the shots louder, directs the muzzle blast up and back more.
That conversation was on this thread:no, that is what a muzzle brake does. and it does NOT make the shot louder, it simply redirects MORE of the shot signature back towards the shooter thus changing what the shooter hears. the raw noise Impulse is still the same, but with a muzzle brake you might (depending on design) hear more of it.
a flash hider is designed to allow the gasses of the shot to blend with ambient air, expand and cool a little.
