We also rely on fundamental mathematics principles taught in What are vibrations? Many physical systems vibrate or oscillate when something disrupts their equilibrium. Think of what happens when you pull a mass attached to a spring or push a pendulum in a certain direction.

The mass bounces up and down. The pendulum swings back and forth. Hearing becomes gradually less sensitive as frequency decreases, so for humans to perceive infrasound, the sound pressure must be sufficiently high. The ear is the primary organ for sensing infrasound, but at higher intensities it is possible to feel infrasound vibrations in various parts of the body. People use this frequency range for monitoring earthquakes, charting rock and petroleum formations below the earth, and also in ballistocardiography and seismocardiography to study the mechanics of the heart.

Infrasound is characterized by an ability to get around obstacles with little dissipation. In music, acoustic waveguide methods, such as a large pipe organ or, for reproduction, exotic loudspeaker designs such as transmission line , rotary woofer , or traditional subwoofer designs can produce low-frequency sounds, including near-infrasound.

Subwoofers designed to produce infrasound are capable of sound reproduction an octave or more below that of most commercially available subwoofers, and are often about 10 times the size.
