The sound pressure ratios of inlet to outlet have been computed for different noise strength at variable flow conditions. It is shown that the frequency characteristics of sound pressure ratio of inlet to outlet for Quincke tube with strong noise sources are similar to that under linear conditions and the good noise reduction can also be obtained. The sound pressure ratio of inlet to outlet is not dependent on the source if the strength is weak, but the ratio is dependent on the source markedly if the strength is strong In this case, the ratio depends on the frequency too.
