The government of Geneva had a new idea how to keep the youth out of the government buildings. A new installation of speakers emits sounds in the range of 20kHz. These sounds cause headaches to younger people, but can no longer be heard by average citizens after a certain age.
However, this installation is highly based on the concept of the average citizen. There are people who are still able to hear sounds far beyond the 20kHz boundary, while some young people have already damaged their capability of hearing in discos and using walkmans well before they reach the «critical age».
Also, the question remains whether there is any sense in making such a discrimination. What exactly is the point of keeping the youth out of the Palais Eynard?
