The GOST (Global Ocean Security Technologies) Acoustic Barrier can function as a sound barrier or as a traditional siren to effectively stop onboard intruders in their tracks by generating a patented unbearable pattern, frequency and intensity noise. Cheats intruders of the few minutes that could be used between alarm activation and arrival of security or police, protecting secured areas for that crucial period of time and continuing for the duration of continuous signal


Sound barrier mode is achieved by pairs or arrays of units. In siren mode, a single unit overs areas up to 70 square meters/ 750 square feet. Larger areas can be covered with several units. – See more at:
