Their plan is this: Hook up a long-range acoustic device (LRAD) to an MP3 player, and raise the volume to painful sound levels whenever pirates approach.
The noise from the satellite dish-sized LRAD can get so loud that it causes permanent hearing damage.
If threatened ships blast oncoming pirates with “precise beams” of warning messages, sirens, etc., it could be enough to cause “absolute agony” to any ambitious pirates, according to APMSS chief executive Nick Davis, and could make them turn back.
