Work in progress | |||
When you google vibration (in German) the first entries you will get are about safety precautions on working spaces. It says, that their impact on people can range from disturbance and performance loss over health hazard to health damage (Institut für Arbeitsschutz der Deutschen Gesetzlichen Unfallversicherung). | |||
Vibrations are less acoustic and more about a sensory feeling. If something that you are standing on is vibrating you will feel it but you won't either see nor hear the vibrations only what's vibrating is recognizable. The phenomenon is stuck to materials. I would be intersted in de-materialising vibrations and make them noticeable on different levels. I am interested in researching more the concepts of sound and vibration which often are used in similar ways. The idea I would like to pursue is to work on an installation that reacts to vibrations sensed by piezos. It would be nice to have some closed self-fulfilling system that uses and causes vibrations. | |||
In first place I need to work on a stronger signal coming from the piezo element. Therefore I will do more experiments on different OP-AMPs and also different components that can effect the outcome. | |||
