| Abstract: | In this paper we consider the problem of using a network of sensor and actuator nodes, to synthesize a given desired wave field in a given medium -- we refer to this problem the *distributed* Wave Field Synthesis problem (dubbed dWFS). We formulate this problem as one of minimization of a quadratic function, subject to linear (and very sparse) constraints. This formulation results from a finite-element approximation of the underlying wave equation, which constrains the values that a field and the source that induces that field can take. We present a complete solution for a 1D vibration, although our solution method can be readily extended to any number of dimensions. Numerical simulations are included. | ||
