* It is believed sauropods defended themselves by cracking their tails like whips, causing a sonic boom.
** It is not physically possible for them to have been able to generate a sonic boom strong enough to have caused any sort of significant damage to an attacker. They'd have had to actually connect with their tail to hurt anything. Any resulting boom (which would likely have sounded more like a bull-whip) would have simply been a side-effect of them swinging their tail, though it would probably have served as a deterrent noise to most predators.

* Surprisingly, TruthInTelevision. The SR-71 Blackbird, if at its operational max speed of Mach 3.5 above a city (let's just ignore atmospheric friction for the moment...) at anything less than 10,000 feet, would level said city. Hell, simply flying a fighter jet as close to Mach 1 and at near the minimum altitude as they're allowed during peacetime can severely rattle a house. As in lock-the-cupboards-or-everything's-going-to-fly-out-of-them rattle.
** The idea of the SR-71 leveling a city is ''dramatically'' overstated, as was demonstrated on ''Series/MythBusters'', where F/A-18s flying at 200 feet above the deck at Mach 2 were unable to break so much as a ''wine glass''. While there would be a certain amount of damage from the pressure wave hitting flexible sheets of glass, otherwise, there's just not enough energy to do severe structural damage, even at Mach 3.5.
*** A fighter jet at Mach 1 tortures the eardrums of everyone around, but only makes the sheet glass rattle a bit. During an airshow in 1991, a patrol of MiG-29s performed the low-level turns needed to return over the airport over a small lake, between a neighborhood of small houses and another of apartment blocks. They sounded like rolling thunder for viewers, and the very ground rattled, but nothing broke.
** For one SR-71's final flight before its donation to the Smithsonian, it set a world record for fastest Los Angeles to Washington, D.C. flight at 59 minutes. Unfortunately, the flight path took it directly over a Mormon temple, shattering all of its stained-glass windows. Oops...

** The Republic XF-84H test plane had a propeller whose blades turned at a supersonic speed. The result was a ''non-stop'' sonic boom ''at ground level'' with all of its destructive implications.

* ThoseWackyNazis tried to develop an explosive-driven sonic "[[StupidJetpackHitler Wunderwaffe]]" that could knock down planes. It actually worked, producing waves of sound which were highly destructive -- within a range of about a dozen yards. Back to Zeichenbrett!

** And The 'Series/MythBusters'' tested this one too. Using the proper technique a human being can shatter a wine glass with their voice.
* The Chrysler horn (not to be confused with the horn on board Chrysler cars) is a nuclear air raid siren run off of a souped up v8 engine thats designed to warn an entire city from well outside city limits. When cranked up to max volume, these sirens have started fires, broken glass, killed animals, and cause material fatigue to nearby buildings and equipment. The fact that it could start fires with its sound couldn't even be confirmed for almost fifty years, because the sound alone broke the instrumentation needed to confirm this hypothesis (many tried to explain the random grass fires as the siren spewing gasoline due to internal mechanical failures). It can do these things because it has such a large wave amplitude that when the sound collides with an object, it causes a massive vibrations similar to an object at its resonance frequency (only with the Chrysler horn no resonance frequency is needed). These vibrations are then displaced as heat and cause material fatigue, causing stuff to break over time.
* Long Range Acoustic Device weapon can send painful sound wave.
* 200 decibels can rupture your lungs. Luckily, you ''literally'' need a nuke, or copious amounts of StuffBlowingUp at least, to get that kind of noise. In general, that kind of pressure wave (which is the "loudness" part of the sound) is less a sound, and more of an explosion, and even then anything higher than 190 is hard to achieve because our particular atmosphere doesn't really assist much.

waves.
* 200 decibels can rupture your lungs. Luckily, you ''literally'' need a nuke, or copious amounts of StuffBlowingUp at least, to get that kind of noise. The decibel scale is logarithmic; put simply, to register 10 more decibels requires ''ten times'' the power. To compare, a rifle shot generates about 150dB at point blank. A 200dB sound requires ''100,000 times'' more power, and because of the rapid drop-off only applies at the source. In general, that kind of pressure wave (which is the "loudness" part of the sound) is less a sound, and more of an explosion, and even then anything higher than 190 is hard to achieve because our particular atmosphere doesn't really assist much.

* 200 decibels can rupture your lungs. So if you're at a metal concert, try not to stand too close to the speakers.

* Sperm Whales can stun their prey with their Echolocation. This is because a Sperm Whale's clicks can be up to 230 Decibels. They do this to ''Giant Squids''.
