dc.descriptionIn a major part of Ecuador’s territories, especially in the rural areas of the Andes, corn plants are widely spreaded. Most commonly, corn serves as a food source for human beings, although it can furthermore be divided into its components which are leaf, stem and flower. Those apply for varies purposes, such as but not limited to livestock food source, compost material, paper as well as arts and craftwork. This assignment will focus on the corn’s stem used for the process and extraction of an acoustic material based on the plant’s fiber. Its natural origin provides that the manufacture has an ecologically beneficial impact on the environment and allows an improvement of acoustic conditions. Due to its ecological source, it may substitute all kinds of synthetic material. Besides, artificial substances emerge from a polluting process, additionally to its higher cost. Panels of 6, 12 and 24mm thickness have been made. Therefore, the corn plant’s fiber and a connecting component, for example clay, liquid glue or gypsum, have been mixed. While the desiccation of the panels and the extraction of samples, measurements have been taken by impedance Kundt referring to the UNE EN ISO 10534-2 formula that determines: the coefficient of the absorption and the acoustic impedance tubes. Hereafter, several factors must be statistically determined. This includes measurement uncertainties as well as calculations on global and average absorption. Those results were considered to compare different densities and among multiple connecting components. Finally, a critical and representative analysis takes place in which the acoustic covering is estimated for each combination, depending on the density and the type of connecting component used. Last but not least, a comparison between the acoustics characteristics of corn and sugar cane has been made, considering seeing that both fibers are quite similar.en
