Frequently asked questions
Instead of hydraulic valves, we use multiple electric linear synchronous motors to generate acoustic signals in a range of frequencies. Please read our award winning paper (Best paper award 2016 SEG) for more information.
We specify our e-vibes based on the full force (100% drive level) at the lowest frequency. For example our Storm 50 has a force of ~50kN / ~12.000lbs. The lowest frequency it can produce 12.000lbs is 4Hz. Comparable hydraulic sources are unable to reach this. Maximum drive levels of comparable hydraulic sources are 60-70% and the distortion is 20-30% or even higher. This has an enormous negative impact on the “useful signal”. The E-vibes can be used at 100% drive level with only <5% internal distortion.
