TL;DR - If you haven't seen a fighter jet at an airshow, try to. The occasional flyovers here are next to nothing in comparison. It'll blow your mind.

Dude, if you thought that was loud, I went to an airshow where the same jet was: an F-15. This thing flew right in front of us, less than 100 feet over the runway that we were on the edge of. I can't even describe it. With my ears plugged, it was still deafening. The ground, both concrete and soil, quaked. The vibrations through your feet were ridiculous. Your entire body gets pummeled by the thunderous energy of the engines. It shakes the earth and hammers through every molecule of your being. It feels like someone is punching your chest or it's going to disintegrate you.

I don't know how close to the speed of sound it was going, but it was fast. It would do the runway passes then pull straight up and turn into a dot in seconds and punch through the clouds. You'd still hear it somewhat faintly lurking above, or fade to borderline inaudible, then it would punch back through and approach until it did another apocalyptic runway pass at breakneck speed.

I was a kid when I went and it's still one of the coolest things I've ever seen. The F-15 is so badass.
