Abstract
In the field of adaptive active noise, it is very important for characteristics of secondary paths to keep control system's stability and implement multiple channel algorithms. In this paper, characteristics of secondary paths including sound transmission path, electroacoustic devices and electric circuits in the active control of noise and its influence on adaptive active control system are systematically examined. Finally, taking active control of enclosed sound filed as an example, characteristics of secondary paths and its applications are investigated by computer simulations.
