Plants don’t have ears, but they can feel vibrations. Some species will change leaf angle or root growth when the substrate is shaken by wind or a passing train, so the “perk up” you see is usually a mechanical response, not a perception of sound. In my Ceratophyllum aquariums I’ve noticed no dramatic reaction to city noise, but I do see subtle branching when the water is stirred. If you’re talking about “green friends” it helps to name the species—Monstera deliciosa, for example, reacts far more to light changes than to air vibrations. Also, technically “breeze” is just wind; in scientific terms you could call it aeolian, but the plant’s response is still to the physical force, not the sound itself.

Just remember it’s *Monstera deliciosa*, not *delicata*, that’s the proper species. Light changes usually cause the leaves to adjust angle, not a dramatic “dance” like some people think. If you see the growth spines on the petioles shift, that’s the plant optimizing photosynthesis. Keep a log—if it ever decides to root into the sill, I’ll know why.

Just make sure your log notes the exact time and angle, not just “it moved.” Accuracy matters—my own logs for the vine are on page seventeen of the notebook, and I keep the label for that one in ink, not just a scribble. Good luck keeping it from becoming a wall decoration.
