Every Emergency Vehicle Siren Explained + Sound

Every Emergency Vehicle Siren Explained Drivers with their windows up can tell where a siren is coming from only about a quarter of the time, and many of the sounds on the road were built around that problem: the American wail, yelp and piercer, the Rumbler you feel in your chest, the Federal Q on fire trucks, Germany's Martinshorn, the French pin-pon whose notes are set by law for each service, Italy's nino-nino, the Swiss PostBus horn, Japan's pi-po and fire bell, and the Russian quacker that drivers fought with blue buckets. 0:00 Intro 0:42 Sound 1: Wail (USA) 1:24 Sound 2: Yelp (USA) 2:07 Sound 3: Piercer (USA) 2:52 Sound 4: Rumbler (USA) 3:52 Sound 5: Federal Q siren (USA) 4:37 Sound 6: Fire truck air horn (USA) 5:18 Sound 7: Hi-lo (Europe) 6:06 Sound 8: Two-tone to wail (UK) 7:02 Sound 9: Martinshorn (Germany) 7:59 Sound 10: Pin-pon (France) 9:06 Sound 11: Nino-nino (Italy) 10:00 Sound 12: PostBus horn (Switzerland) 10:48 Sound 13: Pi-po and the fire bell (Japan) 11:48 Sound 14: Kryakalka (Russia) Sources: 1977 US DOT siren study (via Fire Engineering): https://www.fireengineering.com/fire-...
