Infrasonic refers to sound waves and vibrations with a frequency below the range that humans can hear. The frequency of infrasonic sound waves is less than 20 Hz. The range of frequencies can extend to geologic vibrations that take 100 seconds or longer to complete one cycle.
Some examples of infrasonic sounds include: Thunder, Earthquakes, Volcanoes.
Some animals that use infrasonic sounds to communicate include:
Exposure to infrasound at levels above 110 dB can cause changes in blood pressure, respiratory rate, and balance. Levels above 140 dB can cause physical damage to the ear or hearing loss.
