NARRATOR: ??This is the Berlin Wall of sound. An acoustic reconstruction of the Berlin Wall to remember its victims. The Berlin Wall of Sound is 7 minutes and 32 seconds long - the exact time it takes for sound to travel the length of the 155 kilometer Berlin Wall. You will find its length to be almost unbearable.

But what are 7 minutes and 32 seconds, compared to the 28 years of the real wall?
