Abstract:

Acoustic noise generated by transformers is a serious form of environmental pollution and it affects people's lives. Different methods have been suggested to reduce this form of pollution. This paper describes the implementation of a DSP based active noise control (ANC) system. Based on the theoretical result, different noise control systems were built and studied during this project. Results collected from the noise cancellation testing showed that a noise reduction level of 5 to 15 dB can be achieved. In this paper simulation results are presented, the nature of the problem is analyzed mathematically and the weakness of the commonly used methods are exposed. Finally, the mathematics of an improved fast algorithm is given.
