Noise disturbance and echo in classrooms frequently disrupt students' focus and affect the overall effectiveness of teaching and learning sessions. The "Silent Echo" project is specifically developed to address this issue by creating a low-cost, eco-friendly soundproofing panel tailored for classroom environments. This project utilizes a combination of recycled egg cartons and Plaster of Paris (PoP).
