What Makes Cicadas the Loudest Insects on Earth?

TL;DR

Cicadas are the loudest insects on Earth due to their specialized sound-producing organs called tymbals. By rapidly flexing these organs, they create vibrations amplified by an air chamber in their bodies, reaching volumes of 105-107 decibels. Their life cycles also include synchronization in massive broods that emerge every 13 to 17 years, allowing them to evade predators.
