What Seismo Wave does

Seismo Wave (legal entity SEISMO WAVE SARL) is a French private company headquartered in Lannion (Rospez), Brittany, founded in 1983 and operating with 1-10 employees. The company designs (in partnership with the French Alternative Energies and Atomic Energy Commission, CEA), manufactures, and commercializes high-precision infrasound sensors — microbarometers built on electromagnetic transducer technology — including the MB3a analog sensor, MB3d digital sensor with integrated 24-bit ADC, the MB3a PP dual-pressure-output variant for high-amplitude events, and the rugged SIS-1 portable sensor. Sensors detect pressure variations from 0.01Hz to 28Hz with self-noise below -80 dB.Pa/√Hz at 1Hz, and the company operates its own metrology laboratory equipped with a CEA-designed calibration bench to issue individual sensor certificates.

Seismo Wave also sells the SISTEM ready-to-use portable infrasound station (sensor, power, GSM/3G/4G modem, RS232-to-Ethernet), Wind Noise Reduction Systems (WNRS) in flexible-hose and stainless-steel configurations with 32 or 96 air inlets, and a full accessories line (cables, batteries, packaging, GPS antennas, interconnection boxes). The customer base is concentrated in the scientific research community, civil and military security agencies, and — to a lesser extent — environmental monitoring organizations; products are designed to meet the requirements of the International Monitoring System (IMS) network established under the Comprehensive Nuclear Test Ban Treaty (CTBT) and are classified as dual-use goods under European Regulation 428/2009, requiring prior government authorization for export.

The business model combines hardware sales (sensors, stations, accessories), software licensing (non-exclusive, non-transferable), and professional services including station installation, metrology, and calibration. Distribution is dual-channel: direct enterprise sales from the French headquarters for the home market, and a network of 10 exclusive country-specific distributors spanning North America, Europe, Asia-Pacific, the Middle East, and Africa. Pricing is quote-based in Euros on EXW (Incoterms 2010) terms with a 40% down payment, and after-sale service is delivered from France. Strategic implementation is supported by a partnership with Enviroearth for turnkey station installation worldwide.

Core offering

Seismo Wave manufactures and distributes high-precision infrasound sensors (microbarometers) — including the MB3a analog, MB3d digital, SIS-1 portable, and MB3a PP dual-output models — developed in partnership with the French Alternative Energies and Atomic Energy Commission (CEA). The company also delivers integrated portable monitoring stations (SISTEM), Wind-Noise Reduction Systems, accessories, and certified metrology/calibration services to research institutions, observatories, and civil and military security organizations worldwide.

Product overview

Seismo Wave offers a portfolio of infrasound sensors (microbarometers) including the MB3a analog and MB3d digital sensors developed by CEA, the portable SIS-1 sensor, and the dual-pressure-output MB3a PP variant. These core sensors operate across frequencies from 0.01Hz to 28Hz with extremely low self-noise. The SISTEM is a ready-to-use portable infrasound station integrating one of these sensors with power supply, GSM/3G/4G modem, and data conversion capabilities. Supporting products include Wind Noise Reduction Systems (WNRS) in flexible hose and stainless steel configurations, plus a comprehensive accessories line covering cables, tools, protective packaging, batteries, and interconnection boxes. The company also provides metrology services with in-house calibration using CEA-designed facilities.

Products and services

• MB3a Analog Infrasound Sensor Analog infrasound sensor (microbarometer) with electromagnetic transducer (magnet-coil) developed by CEA. Records very-low-frequency acoustic signals across a broad frequency band (0.01–28 Hz) with extremely low instrumental noise (below -80 dB.Pa/√Hz at 1 Hz) and remote calibration capability. Designed for research institutions, observatories, and security agencies requiring precise atmospheric pressure measurement.
• MB3d Digital Infrasound Sensor Digital version of the MB3a encapsulating a low-noise 24-bit digitizer (ADC), calibration board, time card, and 1 GB storage capacity. Recommended for short-term measurements where integrated digitization is required. Same frequency bandwidth (0.01–28 Hz) and low self-noise as MB3a.
• SIS-1 Portable Infrasound Sensor Rugged-field infrasound sensor ideal for portable systems, remote sites, or as an addition to seismic stations. Small size and light weight enable easy deployment while providing reliable infrasound signal over a wide frequency bandwidth.
• MB3a PP Dual Pressure Output Infrasound Sensor Version of MB3a analog sensor designed for recording high amplitude atmospheric events. Features two pressure outputs set at 2 mV/Pa and 20 mV/Pa, with dynamic range reaching ±10,550 Pa at 2 mV/Pa.

Optional equipment includes weather stations, solar panels, Wind-Noise Reduction Systems, and thermal protection.
• Wind-Noise Reduction Systems (WNRS) Arrays of air inlets connected with pipes to reduce wind-noise and improve signal quality. Available in flexible hose (10m, 18m) and stainless steel pipe (18m, 36m) configurations with 32 or 96 air inlets. Includes the CEA-designed 32-air-inlet WNRS Star Flexible system with 4 branches of flexible hoses divided into 8 branches equipped with crepine as air inlets.
