quote:Originally posted by ROBERTIf you put you ear on a railway track, (not recommended), you will hear the train coming via the steel rail long before you hear it via the air. Perhaps when the train was a mile away.
quote:Originally posted by neilepSo, from what you say there is indeed a limitation to the distance sound will travel through a solid metal rod, or perhaps our capability to detect it is the limiting factor here....still..what ever the case it..it definitely diminishes with distance....
quote:Originally posted by neilepThere IS a product out there which does exactly what you want it to do.
quote:Originally posted by neilepSo, By your understanding...If a perfect rod was capable of being constructed to make a perfect conductorwould it provide a loss-less medium for sound to travel through over vast distances ?
quote:It also depends on the frequency of the sound – generally, infrasound will travel far further, with less attenuation, than ultrasound – hence you can hear the thump of a sub-woofer at distances where you cannot hear anything from the tweeter
