Music from the weather through sound mirrors
Sunday, August 16th, 2009Inspired by sound mirrors, someone suggests musicalizing a weather system through landscape architecture.
BLDGBLOG here proposes a series of sound mirrors to be built in a landscape with regular, annual wind phenomena. A distant gully, moaning at 2am every second week in October, every year, due to northern winds from Canada, has its low, droning, cliff-created reverb carefully echoed back up a chain of sound mirrors to supply natural soundscapes for the sleeping residents of nearby towns.
Or a crevasse that actually makes no sound at all has a sound mirror built nearby, which then amplifies and redirects the ambient air movements, coaxing out a tone – but only for the first week of March. Annually.
Sound mirrors on Greatstone website
Sunday, July 12th, 2009Greatstone.net has comprehensive information on the village of Greatstone, the home to Sound Mirrors, [...] large concrete structures built in the 1920s and 1930s to detect enemy aircraft.
The history section of the website has details of the Denge mirrors, and also the railways and a US bomber which crashed nearby.
Yorkshire sound mirrrors
Sunday, June 7th, 2009Zeppelin Early Warning Sound Mirrors at the Yorkshire – God’s Own County blog.
Between a messenger with a stick in Marathon or a Beacon on top of a hill but before Radar and electronic surveillance there was a humble invention the ‘Sound Mirror’.
Though I’m not sure why they have chosen a picture of the Sunderland mirror, rather than one actually in God’s own county!

The largest ear in Malta
Wednesday, May 6th, 2009A frequent visitor to Malta, ColorGrinder obtained permission to photograph the 200 ft sound mirror in Malta. His pictures are online at ‘Il Widna’ – The largest ear in Malta. They give a good indication of the surviving camouflage paint.
ColorGrinder also has a post about Tracking down the old Malta Railway.
