Core of the idea is an audio track with a sound wave form depicting the exact shape of the Wall. The 7:32 minutes length equals the time sound needs to travel the 155 km Berlin Wall. The audio includes original GDR politician propaganda and border guard voices, embedded in ultra-low frequencies to create a feeling of discomfort and facing a wall. A 30 years old Soviet synthesizer was used to create the sounds. Tagged with the track were portraits of all victims of the Berlin Wall. The experience became the global landing page of SoundCloud for one week.

Within four days after its launch the demanding 7:32 minutes long Berlin Wall of Sound was experienced by more than 100,000 people, liked by over 1,000 and reposted 400 times. Journalists and influential musicians around the world mentioned the experience. The idea reached its target – post-wall generations. An unpopular topic became popular through a pop culture media. Music channels posted it, DJs used the track in remixes. But also the Federal Bureau for Civic Education Germany listed it.

SoundCloud, the world’s leading social audio platform for electronic music, wanted to remember the 25th anniversary of the fall of the Berlin Wall, because the headquarter of SoundCloud is located on the former site of the Berlin Wall. Objective was to give the young post-Wall generation of SoundCloud an experience of the tragic events during the decades of the Berlin Wall. With the name Berlin Wall of Sound the audio track was a Trojan horse giving the audience an unexpected experience: not electronic music but an acoustical reconstruction of the Berlin Wall. Typical for SoundCloud is that you see the sound wave form of the music. This we used for our core idea to create an audio track with a sound wave exactly mirroring the shape of the Berlin Wall. In addition we tagged the timeline of the Berlin Wall of Sound with the 107 victims of the Berlin Wall.
