Description The noise cancellation problem has been studied extensively. Low frequency (acoustic) noise attenuation has faced attention in industrial environments and in automobile applications. The modeling of the one-dimensional case (where sound travels in a duct and hence between 'wave guides') is relatively straightforward for example. In this paper, a laboratory experimentation of canceling noise using the H/sub /spl infin// control algorithm is presented. The setup consists of a rectangular wooden duct fitted with speakers (for actuation and noise) and microphones (for sensing). The system is interfaced to a stand-alone DSP board (dSPACE) with a TMS 320C31 chip and the control algorithm is implemented digitally on the DSP.
