British Air Raid Sirens [ARCHIVAL SOUND]

Released by "Standard Sound Effect (506B)" from the Archives [https://archive.org/details/78_british-air-raid-sirens_gbia0476946b], the sound YOU are hearing is similar to the Siren sound commonly used in Spongebob Squarepants; and this sound proves to be the TRUE origin of that same Siren sound used in Spongebob Squarepants episode "The Algae's Always Greener". Sounds in order: - 1. All clear signal [0:02]. - 2. Air raid alarm [1:06]. Preferred versions suggested by audio engineers at George Blood, L.P. have been copied to have the more friendly filenames for Archives. Enjoy, as I'll upload more Stock/Archival stuff soon.
