Does Sonihull ECO disturb fish and marine mammals?


Ultrasound is beyond the audible spectrum of marine mammals and fish. The low-powered ultra-high frequencies used by Sonihull are completely harmless to marine mammals and fish. Also, the ultrasound frequencies emitted by Sonihull’s transducers do not propagate far from the surface being protected.

Ultrasound should not be confused with low-frequency sound waves which are within the audible spectrum and can propagate for many miles underwater. Low frequency and sub sonic pressure waves are caused by things like underwater explosions and can be disruptive to large sea-dwelling mammals like whales and dolphins.

Unlike anti-fouling coatings, Sonihull ECO does not rely on poisonous biocides or the release of microplastics from ablative coatings to be effective.
