Abstract
Environmental degradation caused by the extraction of the most commonly used materials in the acoustic treatment of enclosures has encouraged researchers to investigate the acoustic potential of natural ingredients and fibers, seeking possibilities for replacements. The acoustic potential of samples made with fibers extracted from the banana pseudostem, without the addition of a binder and with the application of a natural glue, was analyzed in the present study. For the experimental tests, an impedance tube was used, where sound absorption coefficients were verified using the transfer function technique, described in ISO 10534:2, at a frequency range of 100 to 6300 Hz. The results demonstrated that the fiber presents good potential for application at high frequencies, reaching a coefficient of 0.89 at 6300 Hz. In addition, the fiber was found to have similar sound absorption performance to yucca fiber and, at frequencies above 4000 Hz, it was superior to coconut fiber.
