Pioneering Sustainable Sound: Fraunhofer IWU's Mycelium Speaker Project

Fraunhofer Institute for Machine Tools and Forming Technology (Fraunhofer IWU) is leading the charge in sustainable sound technology with their groundbreaking research project on mycelium-based speakers. Spearheaded by a team of innovative researchers, this project aims to revolutionize the audio industry by integrating mushroom mycelium into speaker components using advanced 3D printing techniques.

Traditional transmission line speakers rely on complex geometries and multiple manufacturing steps, resulting in high costs and environmental waste. However, the Mycoustics project at Fraunhofer IWU is challenging this status quo. By leveraging the unique properties of mycelium, researchers seek to create functional speaker components and housings through tool-less 3D printing processes. This approach not only promises superior sound performance but also offers a sustainable solution for speaker insulation and housing.


Moreover, the ecological advantages of mycelium-based materials are significant. Derived from organic substrates such as straw, wood residues, or brewery by-products, mycelium stands out as a cost-effective and environmentally friendly alternative to traditional speaker materials. With minimal energy consumption and fully biodegradable properties, mycelium embodies the principles of sustainability and environmental stewardship.

The basis for the Mycoustics project lies in Fraunhofer IWU's expertise in technical acoustics and additive manufacturing, combined with extensive research in mycelium cultivation and processing. This interdisciplinary approach positions the project at the forefront of sustainable sound technology, with the potential to reshape the audio industry landscape.


As the project progresses, Fraunhofer IWU remains committed to advancing the field of biomanufacturing and promoting sustainable innovation. Stay tuned for updates on the Mycoustics project and its potential to revolutionize sound technology while promoting environmental sustainability.
