โฆ Synopsis
The first step in the economic control of noise from a complete plant is to evaluate the contribution which each individual item of equipment makes to the total noise level. This involves determination of the sound power level of each source and estimation of the attenuation of noise between the source and the point where noise level is to be controlled. The second step is to identify the possible methods of noise reduction and to select the best by cost~benefit analysis. A computer program, based on the OCMA Specification, is helpful in this work.

Most feedforward active noise control (ANC) algorithms require models of electro-acoustic paths. To obtain satisfactory attenuation and keep the system stable these models have to represent the plant well. This, according to the literature, requires estimation of many, often hundreds of coe$cients.
