The transmission loss of silencers composed of Helmeholtz type resonators are computed on the basis of the one-dimensional linearized theory. The theoretical transmission loss characteristics in the middle frequency range are verified experimentally. The performance of these multiple resonators improves with increasing of the number of resonators, and it is unaffected by the flow which has the central velocity below 20 m/s.
