De Appel website:

From September 27 through 30, De Appel exhibited a sound installation by Max Neuhaus. 

On the last day of the exhibition, an event took place in the Marnixbad: Under water music(s) / Water whistle. Visitors had to bring their bathing suits. Neuhaus: 'I became interested in making sound underwater when I realized that one hears in a completely different way in water. Sound travels much faster and further, we hear not only with our ears but also with our foreheads; our whole sense of sound location is changed.'
