With its experience in the field, Enviroearth has developed a turnkey filtering system for infrasound measuring: the WNRS (Wind Noise Reduction System). This noise reduction system exists in several forms that can adapt to use and user constraints:

Modest in size - 10m in length - and designed to be permanently installed in confined spaces, this filtering system can be mounted quickly and provides reliable data. This solution is a good compromise between durability, data quality and affordability.

Modest in size - 10 m in length – flexible pipes, this system is suitable for congested or difficult to access sites. Designed for temporary measurement campaigns, this solution is rapidly deployable and retractable. No tools are required and only one person is enough to set up the filter network within hours to obtain quality data.

Made of flexible pipes, this solution offers rapid installation. 18 meters in length, the system comes pre-assembled and ready to be deployed. This solution is particularly suitable for environments where rapid deployment is required, with limited space. Also, its pipes are more resistant than metal to hostile environments such as nearby volcanoes.

18 meters in length, this system is designed to be permanently installed, provides reliable and quality data. Stainless steel pipe structure provides good protection against corrosion, particularly in coastal and insular environments. This solution is perfectly adapted to large fields.

the best performing system, made in stainless steel to ensure good protection against corrosion. 18 meters in length (up to 36 meters in extension to accurately detect ultra-low frequencies), this system adapts well to large areas and allows high precision measurement on a wide frequency band. This top of the line model allows maximum noise attenuation and high quality data. The addition of valves on the air inlets allows for pressure testing. High-quality materials used for this filtering system guarantees a long durability, robustness and quality.
