Echo-Shield

A MYCELIUM BASED SOUND ABSORPTION SYSTEM

Our project focuses on designing a sustainable mycelium-based sound absorption system for highway noise reduction. The material combines coffee grounds, a natural nutrient source, with gravel, which enhances density and compression strength. Using re-purposed coffee trays as molds, we developed a modular, interlocking component system, ensuring stability and ease of assembly. Gravel adds weight and sound dampening properties, while coffee supports robust mycelium growth. The interlocking system integrates wooden dowels for added stability, and the geometry ensures effective sound diffusion and absorption.

 

Beyond functionality, the life-cycle of this system is inherently regenerative. Mycelium actively sequesters carbon during growth, contributing to a net positive environmental impact. Over time, the biodegradable components degrade naturally into the soil, nourishing it with nutrients. This process supports reforestation and enhances soil health, embodying a closed-loop, ecofriendly approach. This innovative system combines material efficiency, ecological restoration, and acoustic performance, making it an ideal solution for sustainable infrastructure.
