Fungi as Sound Absorbers

Fungal-based material components have emerged as a sustainable sound absorbers in the recent years. The composition and structural properties of fungi, particularly their porous mycelium networks, make them highly effective in absorbing sound across various frequencies. As industries seek eco-friendly solutions, fungi-derived sound absorbers have recieved special attention due to their biodegradability, low cost and high acoustic efficiency. This review explores the structural advantages of fungal materials, their manufacturing techniques and their current applications in fields like architecture, automotive, and environmental management. Additionally, the potential to optimize these materials for enhanced performance through bioengineering is gaining focus of many researchers. Hence, the study highlights the environmental benefits and challenges of implementing fungi-based sound absorbers on a larger scale, aiming to guide future innovations in sustainable acoustic solutions.
