Infrasound - Wikipedia
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.
Infiltec INFRA20 infrasound Monitor - amazon.com
The Infiltec Model INFRA20 infrasound monitor is designed to record, display and analyze infrasound below the human hearing range in the 0.05 Hz to 20 Hz band. Infrasound is produced by wind turbines, helicopters, meteors, avalanches, volcanoes, large animals like elephants, etc.
