| Abstract: | In recent years, researches on the attenuation theory of active sound control and the technique of adaptive active sound control have becn made independently. By optimizing the number and the positions of error sensors, a relation between them is found in this paper. The method and the formulae for optimization are given. The factors affecting the attenuation effects are discussed. All theoretical results are verilied by experiments and the attenuation effects are satisfied. |
