Technology and the Ambiguity of Productiond technology. This study introduces the musical elements and mechanical design parameters of such objects. Three types of wind-instrument automata are classified based on the sounds they make, namely the whistle, pan flute, and slide whistle type. A structural analysis of the mechanisms of four typical ancient mechanical devices is also provided.
