| 总结: | The proposed study aims to demonstrate a standing wave with acoustic propagator. It demonstrates the link between sound pressure and sound waves. A review of literature on sound waves works with Ruben’s Tube and benefit gain from learning sound analysis showed that this topic is continuously gaining its momentum. Nevertheless, application of acoustic from the study science and vibration can bring a lot benefit to the technology for human being such as application of horn antenna. Apart from that, a study on the different type of gas show how each type of gases reacts with the standing waves produced by speaker. Besides, using different size of tube diameter for acoustic propagator shows the effect to the standing wave output pattern. The most interesting in this experiment is to make Ruben’s Tube into integrated system, where the tube would connect to laptop and used software Audacity for data analysis and data collection. All the program is created using the software where the change of frequency, amplitude and speed of gases automatically. Therefore, it would no longer used amplifier to find the suitable frequency to show the best standing wave pattern. Furthermore, the difference result analysis for air and propane gas show that air has higher speed of sound in both size tube diameter than propane. Also, the larger tube diameter makes the flame accelerates faster hence, when the flame touches the tube walls it would generate stronger pressure waves. |
