What pryrotechnics? We were at IOA and Universal last week and didn't see any. I have a son who is extremely sensitive to noises as well. He is now 11 but we could never even go to 4th of July fireworks until 2 years ago. It was the first time in his life he could watch them without completely freaking out. He still can't stand loud noises and was fine on all the rides we went on. I brought earplugs but he didn't even need to use them. We did not see the stunt shows, live stage shows or Wild West show, so I can't vouch for the volume level of these shows. I am being honest because I know that sensitive kids can become absolutely traumatized and refuse to go on anything! This happened at Disney World several years ago. After Tower of Terror my son wouldn't go on one more ride the entire vacation. This time I promised him I wouldn't take him on anything that might scare him and he trusted me and it was fine. I don't recommend Jaws, I tried it first and thought the gun shots and explosions would bother him, so he skipped it. Everything else was fine, have fun!
