Abbot’s Cliff sound mirror art review

Abbot’s Cliff Sound Mirror – Strait of Dover is a picture of a “sound mirror” built during the World War II era for the purpose of amplifying the noise of approaching aircraft. […] Beam’s camera translates light and shadow into a negative, and then a print, the sound mirror takes what is unheard out of thin air and translates it to something we can hear. The old Zen question about the tree falling in the woods is meditative, but it is also scientific: If there is no one around to hear it, it definitively does not make a sound. Similarly, if there is no eye, there is no image.

The effectiveness of Beam’s pursuit is deepened by Section of Abbot’s Cliff Sound Mirror, prints made from charcoal rubbings of the stone mirror itself. […]

How to find planes without radar

Acoustic mirrors: how to find planes without radar, by Al Williams at Hackaday (“entertainment for engineers and engineering enthusiasts”):

While today the acoustic mirror is a museum curiosity, before World War II, it was a method of detecting aircraft. The mirror could focus the sound from an aircraft engine allowing early detection. There are several of these stations still on the coast of Britain and one in Malta. A microphone picked up the sound and the construction wasn’t actually parabolic, they were spherical mirrors. The reason is that a parabolic mirror has to move to determine direction, while a spherical mirror could detect direction by moving the microphone.

Stuck at Dover? See a sound mirror!

Accot's Cliff Sound mirror

The Guardian article How to amuse yourself in a 14-hour queue at Dover suggests: “The A20 between Folkestone and Dover can be an area of breathtaking beauty, with sea views and endless greenery to distract you from your hellish conditions. Get stranded in the right place and you could go and explore the Abbot’s Cliff sound mirror, or the Samphire Hoe nature reserve.”

“Obscure functionalism melting into majestic land art”

The mirrors’ fruitlessness may be forgiven if only because of the uncanny impression one gets that they were built for a future not yet seen or understood. Indeed, its second life as a monument and relic has been more enduring than its first.

Christo Hall visits the sound mirrors on the Kent coast with photographer Stuart Leech and “finds an obscure functionalism melting into majestic land art”, in The Second Life Of Concrete: Brutalism’s Renaissance, published by The Quietus on 10 July 2016.
