Sound waves aren't exactly a physical thing in themselves, it's simply a wave produced from particles in the air bumping into eachother. You can't see the wind can you? |

It's a question of science gentlemen, that's what I would do, to see if it does in fact disrupt the heat-wave, although I would use 2000x JBL sub bass high performance loudspeakers. That's a whole lot of shaking yeah baby!!!! |

As I have looked around to find information on this phenomena Any way read there maybe some answers hear that may help in this experiment or shall we call it the "Sensurround project" http://www.micron.com/k12/lessonplans/sound/waves.html http://www.kettering.edu/~drussell/Demos/refract/refract.html http://www.fi.edu/fellows/fellow2/apr99/soundsci.html http://science.howstuffworks.com/bat2.htm http://www.fi.edu/fellows/fellow2/apr99/soundvib.html http://imagers.gsfc.nasa.gov/ems/waves.html http://cnx.rice.edu/content/m12365/latest/ http://www.umanitoba.ca/faculties/arts/linguistics/russell/138/sec4/acoust1.htm http://www.zephryus.demon.co.uk/geography/resources/earth/cause.html http://www.seismo.unr.edu/ftp/pub/louie/class/100/seismic-waves.html http://hypertextbook.com/facts/2001/PamelaSpiegel.shtml http://www-rohan.sdsu.edu/~rmellors/lab8/l8maineq.htm http://electron9.phys.utk.edu/phys135d/modules/m10/sound.htm Earthquake sounds http://quake.wr.usgs.gov/info/listen/allsounds.html http://www1.gly.bris.ac.uk/~george/noises/text.html http://nuclearweaponarchive.org/Usa/Tests/Trinity.html http://filmsound.studienet.org/articles/ninecomponents/9components.htm http://www.drunkreport.com/reports/smellmovies.htm http://cinematreasures.org/theater/1/ http://www.in70mm.com/newsletter/2004/69/sensurround/about.htm http://www.in70mm.com/newsletter/2004/69/sensurround/intro.htm http://members.aol.com/earthquakemovie/trivia.html Space shuttle sound waves http://www.geology.smu.edu/~dpa-www/columbia/ Well I hop this as some use for the Sensurround project, please do it in the desert, what a sight it well be to hear! Oh and feel, those sound waves and on the look out for them as well, just don't upset the wildlife around there it is there home as well. Enjoy if I come up with any more ideas I'll send it along... |

The waves are moving something, as in your desert scenario. You can see the heat waves flux. Try your experiment in an average climate, with low humidity, and no smoke, fog, or dust. |
