| Popis: | 106 This paper proposes two examples as the basis for the study to discuss the setting of different parameter conditions and the influence of the acoustic field on the acoustic impedance tube. First, according to the ASTM E1050-98 R06ASTM specification, an acoustic impedance tube was designed and tested with the two-microphone transfer function method. Then the properties of the acoustic field inside the impedance tube were calculated by the method of numerical analysis using the sound field simulation software, and The results of experimental measurement and numerical simulation analysis were mutually verified to confirm the accuracy of the constructed numerical model and the feasibility of the method. Then use the model of the standard impedance tube for simulation analysis to discuss the influence of different parameter settings or model changes on the sound field characteristics of the impedance tube, and further sum up the simulation analysis and the actual results. Finally, through the research of this paper, we hope to establish a set of sound field simulation analysis methods. Through this simulation analysis technology, we can shorten the design and development timeline, reduce the cost of experimental test work and assess the feasibility of different acoustic impedance tube modes. |
