i have been watching this thread since it was originally posted. The noise you have described along with the times given points directly to SpaceX.
The sudden start, the almost even rumble and the abrupt ending is how a engine test sounds. For each of the dates and times given directly correlates
with tests at the Mcgregor site.
As far as the one poster who called SpaceX, Tests are not secret and can be seen from public roads around the site. The individual you spoke with may
have been in cali, and quite frankly didnt have any idea of what the test schedule was so replied with a rubber stamp response. Tests are often
performed twice a day 6 days a week and are very much routine. You may question as why you don't hear all of the tests if they are so routine...
Wind, Cloud cover, and being home in a quiet environment contribute to noticing a test. One poster questioned why there didnt seem to be any concern
out of the Mcgregor area, and the easiest response is they are used to it. Test times vary day to day so there is no way to predict when you might
could hear a test.
Just wanted to post some insight and ease any concerns....
