| dc.description.abstract | A numerical method for optimizing the local control of sound in a
stochastic domain is developed. A three-dimensional enclosed acoustic
space, for example, a cabin with acoustic actuators in given locations is
modeled using the nite element method in the frequency domain. The
optimal local noise control signals minimizing the least square of the pres-
sure eld in the silent region are given by the solution of a quadratic opti-
mization problem. The developed method computes a robust local noise
control in the presence of randomly varying parameters such as variations
in the acoustic space. Numerical examples consider the noise experienced
by a vehicle driver with a varying posture. In a model problem, a signi -
cant noise reduction is demonstrated at lower frequencies. | |
