Abstract
This paper investigates the performance of the acoustic pressure minimisation over space and frequency. The theory and simulations of pressure minimisation over space and frequency using single-channel and two-channel systems are presented. Constrained minimisation of the pressure is introduced, to achieve control over the pressure in both frequency and space. The results show that good attenuation is achieved at the desired range over space and frequency using a single-channel system. However better performance could be achieved using a two-channel system.
