WHY DOES A JET ENGINE SOUND LOUDER THAN A LAWN MOWER FROM THE SAME DISTANCE AWAY?

A jet engine sounds louder than a lawn mower from the same distance due to its higher thrust and the nature of the noise it produces. Jet engines generate sound from both the combustion process and the high-speed exhaust gases, creating a broad spectrum of frequencies, including low-frequency sounds that travel farther. In contrast, lawn mowers primarily produce noise from the engine and cutting blades, which tends to be at higher frequencies that dissipate more quickly. Additionally, jet engines operate at much higher power levels, contributing to their overall louder sound profile.
