In a race against time, scientists are exploring new ways to restore natural systems. Alongside traditional methods such as planting trees, reducing pollution and reintroducing native species, a surprising new tool is emerging: sound. Ecologists can harness sound to bring life back to degraded ecosystems.
On land and at sea, natural soundscapes are being replicated to stimulate growth, reproduction and even communication among species. Sound is already being used to restore oyster beds and coral reefs.
In our new research, we found beneficial plant microbes are also receptive to sound. We used high-frequency white noise to stimulate a fungus that promotes plant growth. The noise is a bit like the sound emitted in between channels of an old-fashioned radio.
