Sound of da police

Why do police cars use different variations of their sirens? Sometimes it's a full on siren, but other times it's "woop...woop...woop" with a second or two in between. And other times they don't turn on the sirens at all but just haul ass down the street with the lights flashing. I thought it was about reducing noise to the neighbors if it's late at night, but that isn't the case. I haven't been able to figure out a pattern. Is it something about the urgency of where they're going to?
