How cicadas makes an extreme sound - life cycle of a cicada facts

Cicadas:
A fascinating insects, known for making loud sounds, beyond a normal limit of a bug.
So, how do cicada insect makes noise.
Cicadas produces this loud sounds using their vibrating membranes called Tymbals, which is unusual for insects, because most of others creates sounds by rubbing their specific body parts, known as stridulation.

Some types of cicadas are famous for emerging after very long period of time, know as periodical cicadas, A "Magicicada septendecim" is known for emerging every 17 years, and "Magicicada neotredecim" known for emerging every 13 years.

Female cicada lays eggs on branch or twig, however, stays underground for most of their life span, and feed on sap of plant roots. Molts there for number of times as per their species, and the cicada shells stays under ground to keep the soil quality more fibrous and full of manure.
So, while being underground, they helps to keep better soil quality, and after emerging out, they becomes food of lots of other animals. That's the life of a cicada.

In this episode, I have covered a life cycle of cicada insect and explained how they emits such a loud call, the resulting sound is much more for a small sound emitting tymbals, may be the deep physics behinds this lies in a particular wave lengths, specific distance and vibration timing between two tymbals of both sides, and a position of a listener. May be some more research is needed to dig deeper.
