No, we don't hear it, and we don't feel the rumbling. It just silently appears in the sky. |

You want to have some rumbling? I haven't seen it, but the company I retired from just bought and installed something that can simulate various sound profiles of almost any rocket. Used to see what can survive. And no, this isn't a joke.
* In a room with concrete walls about 16 inches thick * Array of six speakers which are 1,600 pounds EACH (and they are planning on adding more)
* Sound level in the center of the array: 150 decibels (which will rupture eardrums extremely fast) * Cost about low seven figures * Not sure how many watts the power amp is. More than just an amp though.
I have a link to the manufacturer's website - somewhere.
Sit in the center of the array, put some BOC through it, and it would be plenty loud enough for ANY of you. For maybe 10 seconds if that?
