Bookmark or Share- Infrasonics - Meaning, Sources, Detection, Measurement, and FAQs - VedantuInfrasound, also known as low-frequency sound, refers to sound waves that have a frequency lower than the lower range of audibility (about 20 Hz). Because hearing becomes less sensitive as frequency decreases, the sound pressure should be reasonably large for humans to experience infrasound.
- What is meant by infrasonic sound? - Physics NetworkInfrasonic waves are low frequency(less than audible sounds) sound waves and their propagation requires a medium. It’s frequency normally below 20Hz. Infrasonic waves are sound waves in the frequency range 0.1 Hz to 20 Hz typically.
- Infrasound - WikipediaInfrasound, sometimes referred to as low frequency sound or subsonic, describes sound waves with a frequency below the lower limit of human audibility (generally 20 Hz, as defined by the ANSI/ASA S1.1-2013 standard). [1] .
- Infrasound | Description, Example & Application - Your PhysicistInfrasound refers to sound waves with frequencies below the human audible range of 20 Hz. These low-frequency sounds can range from 0.001 Hz to 20 Hz and travel long distances with little loss of energy. Unlike ultrasound, which is above the human hearing range, infrasound can be heard by some animals, including elephants, whales, and giraffes.
- Infrasonic Sound - HyperPhysicsThe 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, avalanches, earthquakes and meteorites.
