Infrasound Technology

Seismo Wave

  • The company SEISMO WAVE specializes in infrasound sensors for the research community and for civil and military security.

    A long-term partner of the Military Applications Division (DAM), the Environmental Assessment and Monitoring Department (DASE) of the French Alternative Energies and Atomic Energy Commission (CEA), Seismo Wave manufactures and markets high-precision infrasound sensors, also known as micro-barometers.

    Designed by the CEA, the MB3a (analog) and MB3d (digital) sensors enable the detection of extreme atmospheric events with frequencies included between 0.01Hz and 28Hz. Both models are characterized by their low self-noise (approx.10db under the low-noise model at 1Hz) and their remote calibration capability. Known as reliable and robust, the MB3 sensors are all in-lab calibrated on the Seismo Wave premises.

    Installed worldwide, Seismo Wave micro-barometers serve in many scientific observation and prevention applications:

    • Meteorology: study of atmospheric pressure, gravity waves, sudden stratospheric warnings, lighting…
    • Volcanology: to track eruptive activity, to understand eruption dynamics, to analyze volcanic ashes (early warning systems for the aviation)
    • Nuclear explosions, quarry blasts
    • Earthquakes
    • Tsunamis
    • Tornadoes
    • Meteors
    • Landslides, avalanches
    • Wind farm emissions
  • Seismo Wave assists its customers throughout their project, from the design of specific accessories to station maintenance.
    Located in France. Seismo Wave has its own laboratory of metrology, with an infrasound calibrator designed by CEA/DASE, to qualify sensors on the frequency bandwidth from 0.01Hz to 28Hz.
    In the R&D department, engineers work on the improvement of infrasound technologies and on the development of new products and accessories (cables, interconnection boxes, etc…).

    Seismo Wave and Enviroearth, its partner for the installation of stations, operate worldwilde for private and public organizations.
    With over 10 year’s expertise in installing infrasound stations. Enviroearth designs customized infrasound stations that are adapted to your constraints, and supplies all the required equipment: vaults, power, datatransmission, Wind Noise Reduction Systems (WNRS).
