Shred your eardrums perhaps, but I doubt it would be fatal.

That SPL equates to about .15 psi, which amounts to roughly 100 lb distributed over the surface of your body.

Don't know about that but when we toured cape Kennedy, they said at one rocket launch site, that no one could be in the vicinity because the sound level wOuld be fatal.

Then I stand corrected.

Maybe it messes up nervous system control of the heart and/or breathing.

Having worked many Shuttle launches and a few Atlas and Deltas, it depends on the rocket and how close you are. Many birds and bats who got too close are seen in remote camera photos dropping to the ground after immediately after lift-off (really ruins the photo). The sound was strong enough (if you are close enough) to break capillaries of exposed skin. This was mostly from the blast overpressure rather than the sustained sound.

That said, I'd be more worried about toxic plumes (SRB exhaust was partially hydrochloric acid when mixed with the SSME exhaust) and any hypergolic exhaust than the sound.

Safe distance in case of an accident for Shuttle was 3 miles. It is less for the unmanned vehicles.
