Touched Echo Technology

 - Jul 12, 2008
You may have been handed the usual tape player and headphones while visiting museums and galleries before, but the Brühl's Terrace in Dresden, Germany takes a big step in providing interactive exhibits.

People just need to rest their elbows on the railing and cup their ears to be transported back to the night of the terrible air raid on February 13th 1945, using technology called "touched echo." While leaning on to the balustrade, the sound of airplanes and explosions is transmitted from the swinging balustrade through their arms directly into their inner ear (bone conduction).

The sound is not audible to the people who are not touching the rail.
