Simulating Acoustic Performance of Mycelium-Based Sound Absorption Panels

Abstract

This research explores the viability of mycelium-based composites, a biomaterial derived from living fungus, for the fabrication of acoustic panels. We investigate the use of computer simulations to understand the effects of different parameters related with the design and configuration of mycelium-based acoustic panels on room acoustics. Given that mycelium-based composites are novel materials and lack comprehensive acoustical data, we employ the results of impedance tube tests to gather the composites’ sound absorption coefficients. This material-specific data is then used as an input for simulations, using ray-tracing and image-source methods.
