Tóm tắt

 Current sound-absorbing materials, reliant on nonrenewable resources, pose sustainability and disposal challenges. This study introduces a novel collagen-lignin sponge (CLS), a renewable biomass-based material that combines collagen's acoustic properties with lignin's structural benefits. CLSs demonstrate high porosity (>
