Journal ArticleDOI
The active minimization of harmonic enclosed sound fields, part I: Theory
TL;DR: In this paper, an analysis of the effectiveness with which active methods can be used for producing global reductions in the amplitude of the pressure fluctuations in a harmonically excited enclosed sound field is presented.
Journal ArticleDOI
The minimum power output of free field point sources and the active control of sound
TL;DR: In this paper, the authors used the near field technique developed by Levine to calculate the total power output from an arbitrary number of point primary and secondary sources, which is a quadratic function of the complex strengths of the secondary point sources.
Journal ArticleDOI
The active minimization of harmonic enclosed sound fields, part II: A computer simulation
TL;DR: In this article, it was shown that when a single mode dominates the response near optimal reductions in acoustic potential energy can be achieved by minimizing the pressure at a single sensor, provided that the source is placed at a maximum of the primary sound field.
Journal ArticleDOI
The active minimization of harmonic enclosed sound fields, part III: Experimental verification
TL;DR: In this article, the authors compared the measured results of active minimization experiments in an enclosed sound field with those predicted from theory, and found that the response of the experimental enclosure was very close to that predicted by the computer model when these problems were overcome.
