Pffft. Pikers.
Loud is the sound of a B1 Lancer at takeoff with full afterburner.
In the right conditions it will echo for 15 miles.
I remember when the B-52s took off at Carswell AFB in Fort Worth.
B-1B takeoff and flyby was the absolute highlight of the Van Nuys airshow... I would schedule vacations to go visit my brother and catch departure day.
I lived a mile from the runway by an AFB that had B1-Bs. Once in a while they did what they called a hot take-off. Full afterburners until you could no longer hear them, which was about 200 miles north of the runway. The local news would warn of an upcoming one sometimes, and sometimes it came as a surprise usually in the middle of the night. I loved it.
