Abstract

In this paper we analyse, from a mathematical point of wiew an active noise control problem for a dissipative acoustic cavity. This problem consists of determining the amplitudes, phases and positions of several monopole sources (speakers) to minimize de noise level at some points due to a primary harmonic source, for example, the vibration of an elastic structure in contact with the fluid. The model of the system is the Helmholtz equation and the Active Control problem is set in the framework of mathematical optimal control theory of distributed systems. We propose a finite element method to obtain approximated solutions.
