  • Method and device for detecting infrasound
    Patent number: 10180348
    Abstract: A method and an apparatus for detecting infrasound that determines the direction and position of an infrasound source. The detection method includes a container exposed to an infrasound source and partially filled with a mist (N) which is embedded in a carrier medium so that the resulting pressure change over time results in the formation of a directed front at the mist surface that can be optically detected.
