Ann Arbor, Mich Tornado Siren Test Ambience (Aug/13/24)

Here's a video of my city's siren test ambience from the Aug/13/24 siren test. The siren units contain several Federal 2001-SRN sirens with 2 2001-SRNB sirens mixed. The loud buzzer horn was a 1960s Edwards Adaptahorn No.372 (120VAC) Fire Horn doing 1 cycle of Code 4-4-4-4. The blue thing you're staring at during the video is a vintage 1940s Cobalt Blue Glass Telegraph Pole Insulator made by The Hemingray Glass company that is located in Muncie IN.
enjoy.
