It turns out SLS has a '40 million times greater' crackling quality than Rice Krispies when heard from a distance of 5 kilometers.
a widely-circulated claim that the sound emitted by Saturn V was loud enough to melt concrete.
"We hope these early results will help prevent the spread of possible misinformation, as happened with the Saturn 5," study author Kent Gee said. "Numerous websites and discussion forums suggested sound levels that were far too high, with inaccurate reports of the Saturn 5’s sound waves melting concrete and causing grass fires.
Overall, the researchers investigated recordings from five microphones — located between 1.5 km to 5.2 km from the launch pad — and found that they all exceeded predicted noise levels, some by as much as 20 decibels. At 1.5 km, the maximum noise level reached 136 decibels, while at 5.2 km, it reached 129 decibels.
"Although this study is an important step forward, we still have a long way to go to understand everything about the generation, propagation, and perception of rocket noise," Gee explained. The scientific community may have a long way to go when it comes to rocket sound models, but at least we know roughly how many Rice Kripies bowls it would take to attain a similar crackling quality to the world's most powerful rocket.
