Abstract:This thesis showcases the development process of a tool for achieving a sustained, non-percussive sound that captures the sonic essence of ceramic objects, a so-called ‘sonic screwdriver’, meant for implementation in iterations of Daniël Maalman’s Lost & Found Orchestra sound art installations. The tool is meant to use a different way of sound excitation than Maalman’s conventional method of simply tapping objects with cores of solenoids. This is done by means of creating an audio feedback loop on the surface of the objects, which allows the objects speak in their own voice by using its resonant frequencies in an audio feedback loop. The audio feedback loop is composed of a contact microphone, a surface transducer and an audio amplifier. The system achieves accurate pitch control of the audio feedback at the resonant frequencies of an object by means of a control signal being input into the audio feedback loop via a second surface transducer. The developed solution can be used as a powerful tool in the creation of many types of sound art.
