Can a shockwave be created by air pressure

WebCheck Your Understanding. 1. A sound wave is a pressure wave; regions of high (compressions) and low pressure (rarefactions) are established as the result of the … WebSep 9, 2016 · You actually hit a limit around 194dB. At 194dB, you can no longer form an undistorted wave because the trough of the wave actually creates a perfect vacuum. So to create a modest pressure, one you could create using your own lungs and diaphragm, you would actually need a louder sound than the air supports! But it does work.

WebNov 24, 2016 · $\begingroup$ I agree with Kyle, though a bow shock can standoff in front of the moving object (sometimes called a piston), the "shocked" gas behind the shock will be greatly heated. In the case of hypersonic flight, there can even be spalation and ionization due to the extreme conditions so I doubt the shock will protect the steak from heat. WebAug 11, 2015 · A 35-45 psi overpressure may cause 1% fatalities, and 55 to 65 psi overpressure may cause 99% fatalities. (Glasstone and Dolan, 1977; TM 5-1300, 1990) BTW, damage in Humans mainly occurs at the interface of areas of different density eg lungs and eardrums. It is essentially a spallation effect like Newton's Cradle in tissue.
