• Resumen

  • With the affordable and available power of digital signal processors, the is currently resurgent interest in the areas of active noise control (ANC), and the closely related technology of active vibration control (AVT). A testbed ANC system using the Motorola DSP56001 digital signal processor (DSP) has been developed and is currently being evaluated for the control of noise in areas of the power industry where personal are likely to be exposed to levels of noise that is above tolerable or legal limits. Vibrating power lines and transformers, or rotating machinery that is causing high levels of noise at acoustics frequencies of 30-300 Hz, give rise to noise fields that are extremely applicable for noise control. Noise above 300Hz us best controlled by active vibration control (AVT) techniques. This paper discusses the application of ANC techniques for the electrical power industry, and presents preliminary results for ANC with a 275 Kv electricity substation transformer
