The NYPD uses a cacophony of sounds to frighten people, pull them over, clear the way, or the most common, blow red lights. The NYT did a breakdown of the various sirens that the boys in blue have at their disposal. And if the 5 they already play with weren’t enough to do the trick, they’re even thinking about adding one with some bass: the rumbler. So study well readers, for as Sun Tzu puts it, “Know Thy Enemy.”
