Saturn V was loud but didn't melt concrete

The Saturn V carried man to the moon and remains the most powerful rocket to successfully launch to orbit. It captures the imagination—but sometimes, it might capture a bit too much imagination. Abundant internet claims about the acoustic power of the rocket suggest that it melted concrete and lit grass on fire over a mile away.
Such ideas are undeniably false. In The Journal of the Acoustical Society of America, researchers from Brigham Young University used a physics-based model to estimate the acoustic levels of the Saturn V. They obtained a value of 203 decibels, which matched the very limited data from the 1960s.
To put that number into perspective, commercial jet engines range from around 120 to 160 decibels.
"Decibels are logarithmic, so every 10 decibels is an order of magnitude increase," said author Kent L.

While concepts for space-based solar power plants have been around for decades, the economics have not added up. That could be changing with the advent of renewable rockets and advancing in-orbit assembly capabilities.
