\/>\nFound the sound (way, way down)<\/p>\n<p>A SCIENCE NOTE<br \/>\nWhat is the science for the very low rumble elephants can hear&#8230; and the vibration you can hear if you put your ear to the ground like the Indians did to hear buffalo running&#8230; or to a railroad track to hear a far off train?<\/p>\n<p data-start=\"0\" data-end=\"175\">Great question \u2014 the science behind these phenomena all centers on <strong data-start=\"67\" data-end=\"96\">low-frequency sound waves<\/strong> and how they <strong data-start=\"110\" data-end=\"146\">travel through different mediums<\/strong>, like air, ground, or metal.<\/p>\n<h3 data-start=\"182\" data-end=\"217\">1. <strong data-start=\"189\" data-end=\"217\">Elephants and Infrasound<\/strong><\/h3>\n<p data-start=\"218\" data-end=\"336\">Elephants communicate using <strong data-start=\"246\" data-end=\"260\">infrasound<\/strong> \u2014 sound waves <strong data-start=\"275\" data-end=\"290\">below 20 Hz<\/strong>, which is beneath the range of human hearing.<\/p>\n<ul data-start=\"338\" data-end=\"895\">\n<li data-start=\"338\" data-end=\"623\">\n<p data-start=\"340\" data-end=\"359\"><strong data-start=\"340\" data-end=\"359\">Why infrasound?<\/strong><\/p>\n<ul data-start=\"362\" data-end=\"623\">\n<li data-start=\"362\" data-end=\"510\">\n<p data-start=\"364\" data-end=\"510\"><strong data-start=\"364\" data-end=\"384\">Long wavelengths<\/strong> of low-frequency sounds travel <strong data-start=\"416\" data-end=\"454\">further through the ground and air<\/strong> with <strong data-start=\"460\" data-end=\"480\">less energy loss<\/strong> than higher-frequency sounds.<\/p>\n<\/li>\n<li data-start=\"513\" data-end=\"623\">\n<p data-start=\"515\" data-end=\"623\">Elephants can send and receive these deep rumbles over <strong data-start=\"570\" data-end=\"597\">distances of 5\u201310 miles<\/strong>, even through the ground.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<li data-start=\"625\" data-end=\"895\">\n<p data-start=\"627\" data-end=\"658\"><strong data-start=\"627\" data-end=\"658\">How do elephants detect it?<\/strong><\/p>\n<ul data-start=\"661\" data-end=\"895\">\n<li data-start=\"661\" data-end=\"754\">\n<p data-start=\"663\" data-end=\"754\">Through their <strong data-start=\"677\" data-end=\"691\">large ears<\/strong>, but also through <strong data-start=\"710\" data-end=\"729\">bone conduction<\/strong> in their feet and trunk.<\/p>\n<\/li>\n<li data-start=\"757\" data-end=\"895\">\n<p data-start=\"759\" data-end=\"895\">Vibrations are sensed by <strong data-start=\"784\" data-end=\"807\">Pacinian corpuscles<\/strong> \u2014 special receptors in their feet \u2014 and then transmitted up the bones to the inner ear.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h3 data-start=\"902\" data-end=\"961\">2. <strong data-start=\"909\" data-end=\"961\">Putting Your Ear to the Ground or Railroad Track<\/strong><\/h3>\n<p data-start=\"962\" data-end=\"1074\">This works on the same principle \u2014 <strong data-start=\"997\" data-end=\"1064\">low-frequency vibrations travel more efficiently through solids<\/strong> than air.<\/p>\n<h4 data-start=\"1076\" data-end=\"1111\"><strong data-start=\"1081\" data-end=\"1111\">Hearing Buffalo or Horses:<\/strong><\/h4>\n<ul data-start=\"1112\" data-end=\"1409\">\n<li data-start=\"1112\" data-end=\"1182\">\n<p data-start=\"1114\" data-end=\"1182\">Hoofbeats on the ground create <strong data-start=\"1145\" data-end=\"1181\">low-frequency seismic vibrations<\/strong>.<\/p>\n<\/li>\n<li data-start=\"1183\" data-end=\"1294\">\n<p data-start=\"1185\" data-end=\"1294\">These waves can be heard or felt <strong data-start=\"1218\" data-end=\"1252\">before the animals are visible<\/strong>, especially in still, quiet environments.<\/p>\n<\/li>\n<li data-start=\"1295\" data-end=\"1409\">\n<p data-start=\"1297\" data-end=\"1409\">Native Americans and scouts often placed their <strong data-start=\"1344\" data-end=\"1375\">ears directly to the ground<\/strong> to detect these faint vibrations.<\/p>\n<\/li>\n<\/ul>\n<h4 data-start=\"1411\" data-end=\"1441\"><strong data-start=\"1416\" data-end=\"1441\">Railroad Track Trick:<\/strong><\/h4>\n<ul data-start=\"1442\" data-end=\"1814\">\n<li data-start=\"1442\" data-end=\"1524\">\n<p data-start=\"1444\" data-end=\"1524\">Steel is a <strong data-start=\"1455\" data-end=\"1492\">very efficient conductor of sound<\/strong>, especially at low frequencies.<\/p>\n<\/li>\n<li data-start=\"1525\" data-end=\"1662\">\n<p data-start=\"1527\" data-end=\"1662\">When a train is coming, vibrations from the wheels traveling down the tracks generate sound that can move <strong data-start=\"1633\" data-end=\"1648\">miles ahead<\/strong> of the train.<\/p>\n<\/li>\n<li data-start=\"1663\" data-end=\"1814\">\n<p data-start=\"1665\" data-end=\"1814\">Putting your ear to the rail gives you <strong data-start=\"1704\" data-end=\"1722\">direct contact<\/strong> with the metal, allowing you to hear the vibrations <strong data-start=\"1775\" data-end=\"1813\">well before you\u2019d hear them in air<\/strong>.<\/p>\n<\/li>\n<\/ul>\n<h3 data-start=\"1821\" data-end=\"1844\">Summary of Physics:<\/h3>\n<ul data-start=\"1845\" data-end=\"2235\">\n<li data-start=\"1845\" data-end=\"1962\">\n<p data-start=\"1847\" data-end=\"1962\"><strong data-start=\"1847\" data-end=\"1870\">Low-frequency waves<\/strong> (infrasound or seismic waves) travel farther and more efficiently than high-frequency ones.<\/p>\n<\/li>\n<li data-start=\"1963\" data-end=\"2104\">\n<p data-start=\"1965\" data-end=\"2104\"><strong data-start=\"1965\" data-end=\"1975\">Solids<\/strong> (like earth or steel) conduct sound <strong data-start=\"2012\" data-end=\"2039\">much faster and farther<\/strong> than air \u2014 sound moves ~343 m\/s in air, but ~5,960 m\/s in steel.<\/p>\n<\/li>\n<li data-start=\"2105\" data-end=\"2235\">\n<p data-start=\"2107\" data-end=\"2235\">This is why <strong data-start=\"2119\"
