Frightening the wits out of soldiers or popping their eardrums till they bleed, are more unexpected ways of targeting one’s enemies. Here we cover the theory that the centuries old ‘Aztec death whistle’ may have had a military use. We listen to the sweet siren songs and church organs of World War II that quickly blew you to kingdom come. We recount the abuse of folk superstitions in Vietnam during the war, as well as the modern police sound cannons (LRADs) that are blasted onto protesters today.
