Infrasonischer

Infrasonischer is the German adjective used to describe phenomena, equipment, or analyses related to infrasonic frequencies. In English, the corresponding term is infrasonic, and infrasonischer serves as the masculine or general form of the adjective in German. It denotes anything associated with sound waves that lie below the lower limit of normal human hearing.

Infrasonic waves have very low frequencies and long wavelengths, enabling them to travel long distances with relatively little attenuation in certain atmospheric conditions. They can be monitored with arrays of sensitive microphones, barometers, and specialized sensors that detect tiny pressure fluctuations in air, water, or rock. This capability makes infrasonischer concepts useful in atmospheric science, geophysics, and security contexts.

Natural sources of infrasonic waves include earthquakes, volcanic eruptions, oceanic waves, and large-weather systems. Human-made sources comprise explosions, large machinery, and industrial activities that generate substantial low-frequency energy. Infrasound and infrasonischer analysis are employed to study atmospheric dynamics, track volcanic or seismic events, and support compliance monitoring for international treaties. Some animals, such as certain mammals, are believed to perceive or utilize infrasonic signals for communication over long distances. Humans generally do not hear infrasonic frequencies, but high-amplitude infrasonic waves can produce felt vibrations or discomfort.
