Interactive sound installation Maastunnel

Mayor of Rotterdam, Ivo Opstelten, opened the permanent interactive installation in the Maastunnel. Rnul made an audio installation with special speakers which focus audio at a specific zone at the south entrance of the pedestrians/cyclists tunnel.
Movement and the amount of people in the tunnel cause different (cultural) voices to be heard in the hall of the tunnel. The voices (including the Mayor) read the poem written by Jan Prins in 1942 for the opening of the Maastunnel in Rotterdam.
