Fungi, the Earth’s quiet pioneers, have been shaping life since the beginning and will likely be here long after we’re gone. Beneath forests, fields, and even our backyards, they weave vast, unseen networks. Each inch of mycelium—the fungi’s intricate web—contains up to eight miles of delicate filaments, like finely-tuned strings waiting to be played. These ancient organisms are deeply intertwined with our lives, impacting food, culture, and ecosystems in ways we’re only just starting to unravel.
In the early 2000s, a strange discovery was made: fungi respond to sound. Even without ears, mushrooms react to different frequencies. High-pitched sounds stunt their growth, while low frequencies help them thrive. Paul Stamets, renowned mycologist and author of Mycelium Running, dove into this on Matt Whyte’s Sing for Science podcast. He explained how indigenous wisdom long recognized that mushrooms react to lightning—a belief science now confirms. Lightning’s 50,000 volts supercharge fungi growth, and Stamets speculates that thunder’s deep, low-frequency rumble might act as an early signal, preparing fungi for the life-boosting electricity and rain that follow.
Fungi, in a sense, are nature’s musicians. They respond to light, chemicals, touch, and now sound. Fungi can even convert sound waves into electrical signals, much like our own ears do. This inspired The Octopus Project to use fungal signals to create music, revealing that fungi don’t emit steady tones like plants. Instead, their sound is dynamic, constantly shifting—a reflection of their sensitivity to the world around them.
Beneath forests, mycorrhizal fungi form the “Wood Wide Web,” connecting plants through underground networks. These fungal webs allow plants to share nutrients and messages, creating healthier, more resilient ecosystems. Mycelium responds to sound, drawing out fungal tendrils like a musician coaxing notes from a silent instrument, quietly sustaining life in ways we’re just beginning to understand.
The implications of fungi’s response to sound are vast. In agriculture, low-frequency sounds could stimulate beneficial fungi, promoting plant growth without chemical fertilizers. In medicine, they might control harmful fungi, leading to safer, more effective treatments. And in biotechnology, sound could enhance the production of life-saving fungal compounds like antibiotics or anti-cancer agents.
Researchers are also exploring sound waves as an eco-friendly alternative to chemical fungicides. High frequencies can inhibit harmful fungal growth, while low frequencies boost the productivity of mushrooms like oyster fungi. This method could revolutionize farming, increasing yields without damaging the environment.
Fungal research is entering a new era, offering groundbreaking possibilities for agriculture, medicine, and beyond. To explore more, dive into Paul Stamets’ work, Suzanne Simard’s forest research, and the Sing for Science podcast.
