No. We operate at similar sound levels and frequencies as dolphins. In fact, the National Marine Fisheries Service sponsored the development of our technology to non-invasively study whales. They have evaluated our FS-3DT product* and stated: "NOAA's Ocean Acoustics Program (NMFS Office of Science and Technology), has assessed the technical specifications of the current version of the FarSounder sonar technology and concurs that, based on the sound source level, signal duration, directionality, and operational frequency band, there are no anticipated injurious effects on marine mammals or other marine species from its deployment."

* Note that our current products (the FarSounder-500. FarSounder-1000 and FS-SPS sonars) operate at similar frequencies, sound pressure levels, ping rates, and pulse durations as the evaluated FS-3DT.
