GLSV received a Phase-II SBIR (topic number N202-089) from the US Marine Corps to develop a next-generation acoustic hailing device prototype. The main purpose of this device is to provide long range non-lethal hail and warn capabilities to deny access into/out of an area to individuals, move individuals through an area, suppress individuals in open and confined spaces, and stop vehicles and vessels by providing intelligible voice commands to vehicle/vessel operators. Other applications include civil defense, campus security, crowd control, and law enforcement. GLSV’s improved hailing device will be compact and lightweight, and will have increased acoustic output levels, improved voice intelligibility at longer ranges, more precise aiming and targeting, and other benefits.
