CAN YOU UNDERSTAND
Certain tones and frequencies can only be heard by younger people. We used this fact to create a large scale audio test/installation in Berlin's Central Station - Hauptbahnhof, to age-test people and help them find out if this film is for them or not.
Once they are done with the test, a trailer plays on the digital screen, depending on their result. Trailer one "for RATED YOUNG", trailer two "for RATED OLD".
