Can planes cause Deafness???

Widespread deafness is a major problem for the villagers of Santhali, in the Kalchini Block of Jalpaiguri district of the Northeast Indian State, West Bengal. At present, the number has crossed the limit and reached more than 2 to 3 thousand. Now it seems that the entire village has turned into 'a village of the deaf.'

What is the cause?

Airplanes. More specifically, airforce planes and fighter-aircraft (especially, Mig-21, Mig-27, Ground Attack Fighters and some Mig-23UB)s, They can produce up to 500 decibels of sound...

A human hearing's pain threshold where sounds start to cause pain is around 120 decibels.

500 decibels is a whopping can of worms!
