RedVox, Inc. develops applications for smart Android and IOS devices with a focus on measuring infrasound.
Infrasound is bass sound below the human hearing range. When sudden and intense as when a door slams, it may be perceived as a startling, palpable sensation. Infrasound can be excited by the movement, vibration or explosion of large things, or by fast objects. Big vibrating sources include earthquakes, tsunamis, bad weather, and power generation systems. Explosive things include volcanoes, breaking waves, quarry blasts, and nuclear tests. Fast things include jets, departing and arriving spacecraft, and meteors.
Recording infrasound used to be complicated and expensive. With the RedVox Infrasound app, anybody can now explore the inaudible sound field around them, and help build a global hazards and noise monitoring network.
