 note = {Attenuation characteristics of the acoustic filters have been studied by an acoustic method [1]. Analytically, they can be obtained by calculating from the equivalent circuits and the method of measurement of the four-terminal constants of the black boxes was reported in Part II [2]. The present paper includes the method of measuring the attenuation characteristics by the electric simulator. Several acoustic elements were simulated by the electric elements and the results obtained agreed well to those by the acoustic method. Without constructing any real models of the silencers we can get the attenuation characteristics by proper selection of the electric elements. Effect of length of the pipe which connects the engine and the muffler was also studied by this method., 資料番号: SA2404827000},
