Conceptual description
Technical description
To make the soundscape recording, we'll need 2 mono microphones on long wires. Attached to a camera, and make the recording. Best is to make the recordings (2 channels) at the same time.
To record the underwater-soundscape, one 'underwater microphone' is needed, and one 'normal' microphone is needed. Both should be placed on a certain distance from the water surface (like 1,5m above and beneath the surface, ).
To play back the soundscape, it will be needed to make a set-up that matches the circumstances of the recording.. So the listener has to stand in between the speakers (which will be placed, 1,5m below (h)ear level and 1,5m high above)

First testresults
Results of the first experiments we did with the under/above water recordings. One of the encountered problems was that the microphone was filling with water..
Left is under water, right is above water. Channels are synchronized.
Contact microphone
We bought a contact microphone to record more accurately. First result is a sound of a computer and its harddisks
Second attempt: a metal bridge with traffic crossing it.
Developments
We have been to Berlin, recording all the places were we have seen art works. At every location, we have recorded the sound the toilet makes, using the contact mic and a regular stereo setup.
The idea now is to collect physical toilet pots and play the sound back through them, using a "contact speaker", if such a thing exists.
