Abstract : The purpose of this study was to investigate the possibility of attenuating fluid pressure fluctuations in a duct by introducing phase-inverted pulses at the same frequencies. Theoretical predictions were made from an analysis of applicable theory. Experimental test results were examined for possible sources of error. Conclusions and recommendations have been drawn from a comparison of the theoretical and experimental work. (Author)
