Sound Absorption Properties of An Open-Cell Ceramic with A High Occupancy Ratio for Recycling of Sediment from Taihu Lake

This paper proposes an open-cell ceramic acoustic material to combat noise pollution, which utilizes sediment from Taihu Lake as its main ingredient. The open-cell ceramic is manufactured using the gel injection molding method to achieve a high occupancy ratio. Simulation and experimental research demonstrate that the open-cell ceramics possess excellent sound absorption properties, particularly in the middle and high frequencies, with high sound absorption characteristics. The unique pore structure of the open-cell ceramics provides multifunctional and excellent mechanical properties, resulting in a lightweight, pore-designable, and broad-frequency sound absorption material that is environmentally friendly, energy-efficient, and renewable.
