A New Negative-Emittance Approach to the Analysis of Sound-Generation Mechanism Labial Pipes

Document Thumbnail

Sound generation mechanism in labial pipes is mostly analyzed through the use of positive feedback concepts, however results are generally of little practical applicability. Negative-emittance approaches considered so far are even less instructive. A new concept of a negative-impedance approach, based on electromechanical analogies and comparisons to electronic oscillator circuits, is presented and its prospects of application discussed.
