Sneezing is caused by irritation to the mucous membranes of the nose or throat. It can be very bothersome, but is rarely a sign of a serious problem. Sneezing can be due to: Allergy to pollen (hay fever), dust or other impurities entering the nasal passages, and manifests itself as a violent extraction of air from the lungs accompanied often by a very loud noise.
Some sneezes can be so loud that they register very high on the decibel scale of noise measurements. As much as many decibels sometimes. So loud that scientists have concluded that if a man sneezes in a forest and there is no one there to hear it a tree will fall on his head.
Some sneezes are indeed so loud that they can be heard round corners or even in the dark.
You must close your eyes whilst sneezing or else your ears will fall off.
Once, whilst driving fast on the highway, I sneezed so violently that it blew out the whole car windscreen. It came out in one piece from its frame and floated ahead of me. I did not lose control and continued to drive fast until I caught up with the frame and it fitted right back in the aperture from whence it left. Luckily, it was not a series of sneezes as sometimes happen, other wise the frame would have popped out and in several times from London to Paris, at which place I would have had to sneeze in a different accent.
This is all true, I tell you. As true as I am imagining it right now.
Sneezing can be loud, audible round corners and in the dark, violent and strong enough to blow out your windscreen or even make you break wind, and can be in different accents.
