Soundproofing

Spent mushroom substrate (SMS)—the main waste from cultivating oyster mushrooms (Pleurotus ostreatus)—was transformed into mycelium-based composites that perform as highly effective acoustic panels. With 40 mm thickness, these panels absorbed up to nearly 100% of sound at frequencies around 600–1000 Hz and consistently exceeded absorption coefficients of 0.5 at higher ranges.
