lisamariewillbe 1 #2 August 17, 2005 Okay I have a dumb question, how fast is the sound barrier and how is it broken?Sudsy Fist: i don't think i'd ever say this Sudsy Fist: but you're looking damn sudsydoable in this Quote Share this post Link to post Share on other sites
Mostly_Harmless 0 #3 August 17, 2005 Breaking the sound barrier is when you exceed the speed of sound and you are now traveling fast then it. I believe here on the ground the speed of sound is around 740 MPH. But as you higher/lower in the atmosphere the speed changes since the air becomes less/more dense._________________________________________ www.myspace.com/termvelocity Quote Share this post Link to post Share on other sites
BillyVance 34 #4 August 17, 2005 The speed of sound does vary, depending on air density and temperature, as well as humidity. However there's not much variation. Check out this cool mpeg video of a fighter jet doing a supersonic fly-by off an aircraft carrier! http://www.kettering.edu/~drussell/Demos/doppler/mach1.html Click on the MPEG Movie link for the video"Mediocre people don't like high achievers, and high achievers don't like mediocre people." - SIX TIME National Champion coach Nick Saban Quote Share this post Link to post Share on other sites

j0nes 0 #12 August 17, 2005 i don't think the pilots hear the sonic 'boom' as they are travelling faster than the speed of sound. since i've never broken the sound barrier in a plane, I can't say for certain. Quote Share this post Link to post Share on other sites
Vertifly 0 #13 August 17, 2005 You're right. The sound of the boom would not travel fast enough for them to heard. Until at least when they slow down again....Which, by then, the sound waves are like to have disseminated to the point where they couldn't be heard anymore. If they slowed down right away, they'd probably hear it and feel it. I wonder if there is anything to hear on the way back down. hmm??? Quote Share this post Link to post Share on other sites
BenHall 0 #14 August 17, 2005 Call me a nerd, but those planes haven't broken the sound barrier yet, they're just getting close. I'll leave it up to someone else to explain critical mach numbers and whatnot. Quote Share this post Link to post Share on other sites
Dagny 0 #15 August 17, 2005 Those pictures are really cool. I seriously had to ask Kris if they were real or not. He tried to explain it to me, but I still don't get it. Still, cool pics!

In the childhood photos of the kid who sees dead people, there is that same distortion in the pics. Can planes see dead people?

"Sound" is just a compression wave repeated over and over. A sonic boom is one (or a few) compression waves in a row. Around the aircraft, the compression is static; there's nothing to hear. It's only when you move the compression wave over the ground (by moving the airplane) that it's perceivable as a sonic boom.

I thought that effect happened when planes were transonic (due to uneven airflow some parts of the plane are supersonic, some subsonic). Am I wrong?Do you want to have an ideagasm?
