THE ACTIVE CONTROL OF INTERNAL COMBUSTION ENGINE EXHAUST NOISE

A project to investigate the application of active noise control to engine exhausts has been carried out by Ricardo Consulting Engineers using the Essex control scheme for the electronic cancellation of noise and vibration. Two adaptive control algorithms based on repetitive cyclic noise have been tested. The two algorithms are called 'Power Sensing Method' and 'Transform Method'. Comparison of the results shows that the 'Transform Method' algorithm gives much better results when applied to engine exhaust noise under field conditions. The superior performance of the 'Transform Method' is mainly due to its inherent resistance to background noise. In addition, it achieves optimum cancellation within seconds whereas the power sensing system may take minutes.
