alt Hacker NewsI'm not sure how that matters. A sonic boom in a phenomenon not an SPL reading. The goal should be to have a direct metric for how loud/how much it disturbs things is. "boomless" and "speed" aren't a direct metric. If someone makes a sonic boom that's quiet enough, that's fine too.
I'm not sure how to respond to this because it's really just ignoring what I said entirely (maybe due to a lack of context?) and instead responding to things that I didn't say. "Supersonic for supersonic's sake" makes no sense.
