\nA modern acoustic mirror has been built (circa 2003?) alongside the Palmarsh Footbridge over the Royal Military Canal<\/a> in Kent, close to the Hythe sound mirrors<\/a>.\n<\/p>\n

\"Hythe<\/a><\/p>\n

\n
\nThere is a listening mirror on the north (far) bank of the canal, and a speaking point on the south (near) side. The idea is that you can use the mirror to talk to someone 23 metres away on the opposite bank, but as I was on my own I couldn’t test it!\n<\/p>\n

\nUpdate from Paul Devall: It does work. We have taken many visitors across to have a go!<\/q>\n<\/p>\n

\"Hythe<\/a><\/p>\n

The information boards on the mirror and on a mini mirror-shaped stand give some brief details of the history of the acoustic mirrors in English and réflecteur acoustique<\/i> in French. They suggests that you can’t visit the surviving examples, which is a bit misleading, as the Abbot’s Cliff<\/a> and Redcar<\/a> ones are publicly accessible, and the close by Hythe<\/a> ones are on MoD land with permissive access.<\/p>\n

<\/p>\n

\nThe modern mirror was made by Richter Spielgeräte GmbH<\/a> of Frasdorf in Germany.\n<\/p>\n
