Summary

DescriptionWW1AcousticMirrorKilnsea(PaulGlazzard)Jan2007.jpg
English: WW1 Acoustic Mirror, Kilnsea, East Riding of Yorkshire, England.


Rare 4.5 metre high concrete structure near Kilnsea Grange, "northwest of Godwin Battery," a relic of the——First World War. On the pipe in front of the acoustic mirror was a trumpet-shaped ‘collector head’, a microphone which could pick up the "reflected engine sound of Zeppelins approaching from the sea." Wires passed down the pipe——to a listener seated in a trench nearby with a stethoscope headset, who would try——to determine the distance. And bearing of any enemy airships.
