Grass resources such as miscanthus sinensis, reeds, and rushes have been used as materials for roofs and floors in Japan since ancient times. These materials are the most eco-friendly and sustainable building materials from the viewpoint of resource recycling, but their use has been declining in modern times due to the spread of high-performance building materials created in the process of modern industrialization. This research is to find a way to utilize such grass resources as sound absorbing materials in interior spaces as one possibility to utilize them again in modern life, and to explore their practical possibilities. As a result of measuring the sound absorption performance of compression-molded boards made from grass resources at different densities and thicknesses, it was confirmed that boards made from Miscanthus sinensis at a density of 0.35 g/cm3 showed a peak sound absorption at around 900 Hz, indicating high sound absorption performance in the sound range of human speech. COVID-19 has caused the problem of noisy talking voices from online meetings in offices, and demand for this material can be expected as one of the means to solve this problem.
