Andrew Joron and The Sound Mirror

Christopher Nelson’s Poetry Blog has an interview with Andrew Joron, “the metaphysician-elect of contemporary American poetry”, about his book The Sound Mirror.

Nelson: Your title, The Sound Mirror—can you elaborate on that synesthetic paradox? Or would that be to explain away the pleasant mystery?

Joron: In one sense, the idea of a “sound mirror” is not a paradox. Part of the science of acoustics is concerned with the way sound is reflected from surfaces such as the walls of a concert hall. And before the invention of radar, England constructed huge hemispherical “sound mirrors” out of concrete and placed them in open fields as listening devices that would amplify the sound of approaching bombers from Germany. In my case, I appropriated the title from an old Sun Ra LP, which has never been reissued on CD. Sun Ra himself got the title from the first commercially available recording device, released in the forties, which was called The Sound Mirror. But you’re right to note my intent to complicate the sound/light relation in presenting this title. Writing that uses the phonetic alphabet becomes a “sound mirror”; I want to emphasize that, while sound may be exiled from the written word, it continues to haunt the scene—the seen—of writing.

Denge mirrors at Exploring Kent’s Past

“Acoustic Sound Mirrors at Greatstone-on-Sea, Lydd” at Kent County Council’s Exploring Kent’s Past.

The remains of three large concrete structures, formerly an anti-aircraft Acoustic Detection installation. Microphones were attached to the three reinforced concrete structures in order to pick up the sound of approaching enemy aircraft. The smallest ‘sound mirror’ was found to be fairly ineffective so it was superseded by a larger dish, 12 m in diameter. This in turn was replaced by a 70m long ‘sound wall’. The structures were built by the RAF between 1930-4. They were rendered obsolete by the introduction of radar in 1935, and by advances in aerial technology.

Kent History Forum photos

Sound mirrors on the Kent History Forum. There is lots of other good stuff on the site, too.

  • Abbot’s Cliff. Including an aerial photo.
  • Denge. on the last official walk … there was round 300 hundred of us.
  • Fan Hole, near Dover.
  • Hythe.
  • Joss Gap (Kingsgate). Joss bay had two sound mirrors one being a slab, this was cut into the cliff near by the castle keep hotel , now replaced by flats.a slight indentation can still be seen near the top of the cliff. Checking the site where the round mirror was, which was a timber frame rendered. a few years ago the telephone cable blocks were still in place.
  • Warden Point. With a good 1978 photo of it about to go over the cliff.

WWII radar in Malta

Radar stations during wartime Malta, by Charles Debono, curator of the National War Museum in Valletta.

… as radar technology was in its infancy, in Malta, the British authorities decided to build an early-warning system, the Parabolic Acoustic Mirror known as Il-Widna (ear), constructed at Ta’ San Pietru, Maghtab.

Il-Widna became outdated when the British government decided to install the first RDF [Radio Directing Finding] in Malta. It is important to say that this was to be the first RDF installed outside the UK.
