| I had a thought the other day...and well...I thought I would ask those of you who would know more about this kind of thing..... If there was a puddle of water...in a city....and it was a freezing cold night....the noise of the city(cars ..horns etc) all over and around the water in the puddle. the puddle freezes solid just as a taxi driver blows his horn.... The question is...does the ice ...hold the frequency of the sound of the taxi drivers horn? If so can it be copied from the ice ..duplicated in digital format...and played back? If not ..well it would make a great theme for a story. I would love to hear your feedback. (smile) Steve |

| Dear SB: "SB" <[Only registered users see links. ]> wrote in message news:[Only registered users see links. ]. .. No. [Only registered users see links. ] I read a story once about a panel that had an extremely slow speed of light internally. Such that panels would be made with a "12 hour" offset, and used as street lights. Such a panel (with a much longer delay) featured prominently in a murder investigation... David A. Smith |

| hummm....but there must be a point ..just before the phase change..that may not have contained the taxi's horn...but ambient city noise?????

In order for a waveform to be captured, the freeze time would have to be much, much faster than the propagation of the wave form. PD |

| Dear SB: "SB" <[Only registered users see links. ]> wrote in message news:[Only registered users see links. ]. .. Sound is a pressure wave. Freezing involves degassing the liquid, and forming a crystal structure. Crystal formation might have carried some hint of the sound wave, but degassing would have wiped that all out, since it is very much like a shock. David A. Smith |
