  • Hear Where We Are
    Tigers use infrasonics as a hunting strategy, paralyzing their prey in terror before striking.42 Alligators use infrasonic sound in courtship and territorial signaling with bellows so loud that it sets the water surface around them “dancing.”43 They may also use …
  • Monitoring and recognition of debris flow infrasonic signals
    Therefore, long-distance passive monitoring of infrasonic sound sources is possible (Garcés et al. 1999; Mutschlecner and Whitaker 2005; Evers 2008) for analyzing the relationship of infrasound to some disastrous events so as to improve people’s disaster prevention abilities.
  • Low-frequency acoustic vibrations in metallurgical shops
    In view of the low frequency and, thus, long wavelength, damping of infrasonic sound as a result of the viscosity and heat conduction of the medium is very slight, and diffraction phenomena are quite pronounced.
    The second indicator came from abnormal signals of infra- sonic sound waves.
    It is mentioned by many authors and easily verified in a laboratory with suitable equipment that the loudness of low-frequency and infrasonic sound grows considerably faster above threshold than sound at higher frequencies.
  • The simultaneous measurement of infrasonic acoustic particle velocity and acoustic pressure in the ocean by freely drifting Swallow floats
    Difficulties in measuring the underwater infrasonic sound field have long been recognized [5].
  • Springer Handbook of Acoustics
    The range of frequency is also very large, from low- frequency ( infrasonic ) sounds between 10–20 Hz used by blue and finback whales to high-frequency echolo- cation signals that extend to 130–140 kHz or perhaps higher (see earlier mention of 180 kHz).
    (d) Sound waves and propagated vibrations An increasing number of authors favour the idea that fishes would be sensitive to propagated sonic or infrasonic sound waves originating from the usual fin and body movements-or .

  • Bioacoustics, animal
    This inversion layer forms an acoustic duct to trap sounds and allows for good propagation of infrasonic sounds over tens of kilometers, making it possible for elephants in a family group to coordinate their movements over large distances.
