Arlington Cemetary has probably at least monthly 21 gun salutes, via some "smaller" sizes canons or artillery. At 6:30 - 7:30 am. Who hears it and how loud is extremely weather dependent. Sometimes it is stunningly loud & wakes up a reasonable amount of those still asleep across a huge area of DC. Often it's merely noticeable across much of DC. Sometimes you really can't hear it or at least have to be listening very carefully for it. Quite the regular example of sound traveling in very different ways depending just on weather.
