In addition to multi-planetary travel, SpaceX has plans to use the BFR for intercontinental travel. However, would the sound generated by the BFR's launch disrupt local communities and therefore make it unfeasible to set up launchpads across the Earth.

Specifically, how much sound would the two sea level Raptor engines (each with a an approximate thrust of 1,993 kN or about 448,000 lbf) make, and as the sound travels (and loses strength due to the inverse square law) affect nearby communities?

    $\begingroup$ The '2 sea level Raptor' line indicates you assume they'll only use the BFS (the second stage) for intercontinental travel. But the presentations indicate they plan to use the full stack. $\endgroup$ – Hobbes Nov 18 '18 at 12:36
