Mycelium Acoustic Shell

Biogrown acoustic panels engineered for speech clarity and low embodied impact.

Overview

Mycelium acoustic shells are grown, not machined. Fungal networks bind low-value agricultural feedstocks into rigid porous forms that naturally attenuate reverberation in speech-critical frequency bands. This makes them a compelling alternative to petrochemical acoustic foams in learning and civic environments.

Because geometry is mold-defined, designers can produce curved and faceted modules that combine acoustic control with architectural expression, reducing the need for separate decorative cladding layers.

Technology Approach

Performance is tuned through substrate recipe, growth duration, and post-processing. Longer growth cycles increase network density and mechanical stability, while controlled porosity shapes absorption behavior across frequency ranges.

A robust product specification usually addresses:

  • Target reverberation reduction by room use-case.
  • Durability in high-touch public interiors.
  • Fire strategy and approved surface treatments.
  • Moisture tolerance for seasonal humidity variation.

Applications and Implementation

Typical deployments include libraries, school commons, multipurpose halls, and cultural venues where speech intelligibility and warm material character are priorities. Modules can be mounted as wall clouds, ceiling baffles, or geometric corner absorbers.

Implementation works best with an early acoustic simulation loop and on-site commissioning measurements. This closes the gap between predicted and perceived performance before full build-out.
