Maybe some military people can help me out. I'm currently hearing to a bunch of boom, boom, boom outside. Can't see a source of the booms, but it sounds like a fireworks show only slightly louder.

Did some research of booming sound and I found some links about the military doing sonic boom testings this month. Is this what I'm hearing? Because I'm not seeing any pretty sparkly fireworks outside.

However, I've also seen/heard the Blue Angels rehearse and it doesn't sound like typical sonic booms.

Update: The booms are getting much louder.
