[Intro]
(The sound)
… it comes in clear
With your ear
(To the ground)
[Verse 1]
You know
Hearing buffalo
(Low, way down low)
The direction
… the flow
(Low, way down low)
[Chorus]
The sound (the lowdown)
What you hear (comes in clear)
With your ear (way down near)
… touching the ground (way, way down)
[Bridge]
Low frequency (efficiently)
Did move through solid (especially)
[Verse 2]
You know
Hear the elephant rant
(Low, way down low)
Gettin’ down
With infrasound
(Ya know, down low)
[Chorus]
The sound (the lowdown)
What you hear (comes in clear)
With your ear (way down near)
… touching the ground (way, way down)
[Bridge]
Low frequency (efficiently)
Did move through solid (especially)
[Chorus]
The sound (the lowdown)
What you hear (comes in clear)
With your ear (way down near)
… touching the ground (way, way down)
[Outro]
Get down (way, way down)
Found the sound (way, way down)
A SCIENCE NOTE
What is the science for the very low rumble elephants can hear… and the vibration you can hear if you put your ear to the ground like the Indians did to hear buffalo running… or to a railroad track to hear a far off train?
Great question — the science behind these phenomena all centers on low-frequency sound waves and how they travel through different mediums, like air, ground, or metal.
1. Elephants and Infrasound
Elephants communicate using infrasound — sound waves below 20 Hz, which is beneath the range of human hearing.
-
Why infrasound?
-
Long wavelengths of low-frequency sounds travel further through the ground and air with less energy loss than higher-frequency sounds.
-
Elephants can send and receive these deep rumbles over distances of 5–10 miles, even through the ground.
-
-
How do elephants detect it?
-
Through their large ears, but also through bone conduction in their feet and trunk.
-
Vibrations are sensed by Pacinian corpuscles — special receptors in their feet — and then transmitted up the bones to the inner ear.
-
2. Putting Your Ear to the Ground or Railroad Track
This works on the same principle — low-frequency vibrations travel more efficiently through solids than air.
Hearing Buffalo or Horses:
-
Hoofbeats on the ground create low-frequency seismic vibrations.
-
These waves can be heard or felt before the animals are visible, especially in still, quiet environments.
-
Native Americans and scouts often placed their ears directly to the ground to detect these faint vibrations.
Railroad Track Trick:
-
Steel is a very efficient conductor of sound, especially at low frequencies.
-
When a train is coming, vibrations from the wheels traveling down the tracks generate sound that can move miles ahead of the train.
-
Putting your ear to the rail gives you direct contact with the metal, allowing you to hear the vibrations well before you’d hear them in air.
Summary of Physics:
-
Low-frequency waves (infrasound or seismic waves) travel farther and more efficiently than high-frequency ones.
-
Solids (like earth or steel) conduct sound much faster and farther than air — sound moves ~343 m/s in air, but ~5,960 m/s in steel.
-
This is why animals like elephants, and indigenous peoples or scouts, can “hear” things that seem far away or invisible.
