In the most of acoustic system with low flow rate and low pressure level. one-dimensional. linear model ing techniques are used very well. At low frequency, the<br/>
tubes is modeled as inertia element and cavity as capacitance element, and to extend the range of frequency normal mode oscillators are represented. Bond modeling techniques are proposed to predict TL(Transmission Loss) and time response analysis which is impossible by transfer matrix in muffler system. An simple acoustic filter which consists of several tubes and cavities is analyzed in both time and frequency domain.
