Noise Sources Recognition Based on Independent Component Analysis Technology
Deng Ji · Internal combustion Engines · 2009
In order to reduce the engine noise, it is needed to find an effective way to identify the internal combustion engine noise sources. A new independent component analysis technology is used to separate the internal combustion engine-aliasing noise signals, combining with noise generated principle to identify a single noise component correspond to the internal combustion engine corresponding noise source. Thereby the internal combustion engine noise sources are identified effectively. Practice has proved that the technology can identify the internal combustion engine-aliasing noise effectively. Suggestions for the noise control are proposed.
