Possible ways of building a noise power control system are studied. The system is based on adaptive filtering principle and meet high requirements to tuning accuracy. Numerical simulation models of possible processing algorithms were developed, and algorithms were ana-lysed. Those algorithms use different approaches to noise power estimation and approximate calculations. Comparison is provided, and the most effective algorithm was choosen following criteria of quality of tuning, convergence time, computational requirements.
