In this paper, we propose an active noise control (ANC) system without secondary path model (C ^ filter). The proposed system is based on the simultaneous perturbation optimization method with block process. Consequently, the coefficients of the adaptive filter in the proposed system are updated by
In this paper the outdoor active noise control of the sound pressure created by an incoherent line source is studied. Such a source is a model for the noise generated by road traffic or by trains and consists of a continuous distribution of uncorrelated point sources. By using this model, the possib
Existing theories for predicting the distribution of sound intensity in rooms and the performance of acoustical barriers are applied in designing a barrier to reduce noise in an industrial environment. The combination of the theories is found to predict the sound pressure level in the barrier shadow
