| Summary: | 碩士 === 逢甲大學 === 電聲碩士學位學程 === 97 === The main purpose of this thesis is to find out the influence of the acoustic impedance tube internal sound field by setting different parameters and conditions.
Firstly, design an acoustic impedance tube according to ASTM standard and using two microphone method to do a measurement, then calculate the internal sound field characteristic by numerical analysis of simulation software, then verify the correlation by above-mentioned result and to determine the accuracy and feasibility of the numerical model.
Secondly, using a standard impedance tube model to execute a simulation analysis, to discuss the influence of sound field characteristic in impedance tube by setting different parameter or model, and then generalize the result of simulation and measurement.
Finally, look forward to explore a sound field simulation method from this research, to decrease development period and experiment cost, and also assess the feasibility of different mode.
