Fungal Resonance Mapping

Measuring the mechanical resonant frequencies of living mushroom fruiting bodies by exciting them with swept-sine audio signals and recording the response through contact transducers. Different species, growth stages, and hydration levels produce distinct frequency response curves — structural diagnostics through acoustic interrogation.

Two Hundred Twenty Hertz of Marshmallow

The frequency sweep produced a curve that looked more like a marshmallow than a resonance plot. Turns out living mushrooms are terrible oscillators.
