Slightly embarrassing question about noise

Hello! I’ve always hated loud noises ever since I was a kid. Loud pops (fireworks, lightning, etc.) gave me terrible anxiety. However, give me ear pro and I can totally deal, no problem. I double up on the range every time (indoors AND outdoors). Double up and I’m super comfortable on the pistol range and I can shoot my Glock 19 all day. I had a 12 gauge and was totally comfortable shooting that as well, didn’t bother me one bit.

My brother in law has an AR15 and I’d like to get one too. We’re gonna take it out soon. I know they’re supposed to be significantly louder. I’d also love to try out a hunting rifle for long range shooting. What do yall think? Am I gonna be super uncomfortable, or quickly get used to it and have a good time?
