How loud is 200 decibels
Sounds between 170-200 dB are so intense that they can cause lethal issues like pulmonary embolisms, pulmonary contusions, or even burst lungs. As for exploding heads, you can expect that from sounds above 240 dB. However, such high intensity sounds are very rare.
Why is 194 dB the loudest sound possible

Is 300 decibels possible
Over 1,000 scientific papers have been published on the Tunguska event, but it's impossible to know just how strong the sound was — it's quite likely that the Tunguska event could have reached 300 dB. This could almost certainly be the loudest sound ever experienced by mankind if it were not for another event.
