Sounding Place: River drone

This is an idea I stumbled on while I was trying to do something else. It is a bridge or river harp and is similar to a windharp except that the current vibrates the strings instead of the wind. The resulting sounds vary depending on the length and gauge of string used, the speed of the current and where in the river you hang them. My favorite thing about these is that as algea builds up on the strings they grow quieter and eventually stop singing altogether. You also get an occasional leaf or other debris banging into the strings which add sudden sounds to the drones. This particular recording was made with 2 different gauge strings in slower water so the sounds are quite low. Enjoy.

Survivors of the Water World - measuring pollution by sound in the River Göta Elv.

Akerselva, the river running through Oslo, was recently polluted with 6000 litres of chlorine by the council waterworks. All life was erased/killed. There will be no sound made by living creatures in the river for a long time.
By listening with very sensitive hydrophones I suggest you can measure pollution levels in a river. Certain insects can survive certain pollutants, different types of insects and other invertebrates have different tolerances to pollution and they make different sounds. If an organic pollutant is present bacteria will be in abundance and will consume the oxygen in the river. First, the more sensitive invertebrates and fish will die later and so also the more tolerant fresh water shrimp, blood worms or spices like rat-tailed bloodworms. If high concentrations of inorganic pollution such as the chlorine spill in Oslo is poured into to the river, all life will die immediately.
