Abstract
A recent university research project involved the creation of an environmentally friendly sound absorbing panel using bamboo. The goal of this research was to produce a panel with a sustainable material that could be used in similar applications where wood fiber sound absorbing panels would be employed. The test bamboo panel has been made from bamboo rings approximately 1.6 mm thick cut from bamboo stalks with diameters varying from approximately 6 to 50 mm. The bamboo rings were randomly formed into a panel about 25 mm thick using an environmentally friendly adhesive with very low viscosity. Panel sound absorption has been determined using the reverberation room method, an in situ method, and an impedance tube method. [This research was partially funded by an Acoustical Society Robert W. Young award.]
