Planes do it super low I think. I live near an airport and generally it isn't too bad, but one time we must have had a HUGE plane take off. I mean everyone in our apt complex went outside and my metal overhang on our apt was literally shaking and did so for a good 20 seconds. It was crazy at first as it was taking off, as we heard it super clearly from in the house and it kinda felt like an earthquake.. The 20 second later point that plane had to be several miles away at the speed those things move and it still had energy left to keep moving that thing.. A big planes that they probably got the 150db at close range is probably at like 8hz or something silly.
