[Request] How accurate is this?(i.redd.it)

Minor correction to the number of jets though.

A jet takes off at about 140 dB. Let the number of jets required to get to 163 dB be x

140 + 10 * log(x) = 163

10 * log(x) = 23

log(x) = 2.3

x = 10^2.3

x = 199.52 ≈ 200 jets

The second link I posted even has it as 150 dB! This would mean 20 jets! The distance from the jet and the type of engine is not specified! :O
