This thesis introduces the basic research work on the development of the Narrowband Active Noise Control System (ANC). It focuses on providing the noise generator. It combines the virtual instruments’ hardware with software close to realize the function on three main parts: they are data acquisition, data analysis and extraction and noise sound generation, which is based on sound card for the A/D and D/A transformation. This system can not only be used to provide narrow band noise signal for the research of ANC, but also be widely applied to various fields such as diagnosing malfunction, spectrometric computation, signal source and so on.
