DescriptionResearch into materials that are able to absorb low frequency sound waves has become an increasing field of study because of noise pollution in our daily lives. To combat noise pollution created by airplanes, researches have been looking into new light and thin materials to solve the problem. To test these materials a device known as an Acoustic Impedance Tube needs to be used. These devices can either be purchased from a retailer for thousands of dollars or built in house for a fraction of the cost. Using ASTM standards, guidelines for building a tube are presented, but there is not much information into what the tubes results should look like for specific materials. There is also not much information on how the output will change when certain design parameters are modified. The work presented in this paper is not just a guide to help others build an impedance tube but it also can be used to check their own tubes results.
