The whistle's sounds, analyzed through its functioning mechanism, have been noted to resemble the sound of wind and fall within the human hearing sensitivity range. Experimental models of death whistles have been constructed and tested to explore hypotheses and for use in conferences and demonstrations, given that the original ancient ...
