Initial Tests!

For our first tests for picking up sounds from various sources we are using piezoelectric transducers (like contact mics).

Piezo attached on wall..

Second version with amplifier..

Third version with stronger amplifier..

We attached the piezos on various places around my flat. These include:
- freezer
- thermostat
- radiator
- water pipes
- window
- coffee-maker..

radiator sounds..

the sounds of London from my window..

These sounds were recorded on a computer. Listening to the 'raw' sound files we realized that it is difficult to distinguish the various elements (e.g. flowing water, motors, voices etc.) so we used special software (Sound Studio) to filter through different frequencies..

Unfortunately we haven't found a way yet to upload sounds on the blog..
