This paper reports the performance of a single-channel active noise compressor cancellation system. The active noise canceller (ANC) was developed based on a PC-hosted Analog Devices Inc., a low-cost 16-bit fixed-point Digital Signal Processor (DSP), mounted in a two-channel analog I/O board connected to the real world via standard consumer audio components. The algorithm implemented here was the single-channel filtered-X LMS. In the first part of this paper, the noise generated by the compressor will be characterized, followed by the selection of a coherent reference sensor for the ANC implementation. Finally, the noise attenuation achieved with the application of the ANC is presented.
