Saturn V was loud but didn't melt concrete

Abundant internet claims about the acoustic power of the Saturn V suggest that it melted concrete and lit grass on fire over a mile away, but such ideas are undeniably false. Researchers used a physics-based model to estimate the rocket's acoustic levels and obtained a value of 203 decibels, which matched the limited data from the 1960s. So, while the Saturn V was extremely loud, that kind of power is nowhere near enough to melt concrete or start grass fires.
