The ubiquitous five-second-period infrasonic signals called "microbaroms", which are generated by standing sea waves in marine storms, are the cause of the low-level natural-infrasound background …

infrasonics, vibrational or stress waves in elastic media, having a frequency below those of sound waves that can be detected by the human ear —i.e., below 20 hertz. The range of frequencies extends …

Mar 9, 2025 · Infrasound (aka subsonic sound) is the term used to describe sounds that are so low that we can't hear them. Humans can hear within a range of around 20Hz to 20,000Hz (audible …

The term "infrasonic" applied to sound refers to sound waves below the frequencies of audible sound, and nominally includes anything under 20 Hz. Sources of infrasound in nature include volcanoes, …

Feb 9, 2025 · Infrasonic waves are sound waves with frequencies below the range of human hearing, typically defined as waves with frequencies less than 20 Hz. While humans cannot perceive them, …

Jun 11, 2022 · Whales, including blue whales and fin whales, communicate using infrasonic calls that can travel across ocean basins. Giraffes and some reptiles also emit low-frequency sounds to alert …

The meaning of INFRASONIC is having or relating to a frequency below the audibility range of the human ear.

Sep 25, 2025 · Infrasonic refers to sound waves that have frequencies below the range of human hearing, typically below 20 Hz. These low-frequency sound waves are often produced by natural …

Mar 20, 2023 · Infrasound refers to sound waves with frequencies too low for humans to hear. It can have various effects on both humans and animals.

Infrasonic waves, or infrasound, are sound waves with a frequency below the lower limit of human audibility, which is approximately 20 Hertz (Hz). The study of these low-frequency sound waves is …
