We all think of plants as silent, but they're not. 🌱

Plant bioacoustics is the study of how plants generate and respond to sound. Turns out, plants aren't silent at all. It's just that the sounds they make are outside our hearing range, mostly being ultrasound.

Plants which are distressed by lack of water even squeal at around 20-100 kHz. We can't hear that, but some animals can. Moths will even avoid these distressed plants and lay their eggs on healthier leaves.


@InvaderXan How much acoustic power are we talking about here?
