Are there any plants that make noise?

Even in dead calm if you have a large crop you can here corn grow. Corn grows so fast and is planted so dense that tension builds between touching parts of the plants, this tension is released rapidly creating sound. We grow several acres of selectively bred and/or genetically modified corn that by law must be isolated in greenhouses. We have no puffs of wind here but do have noise. Also the plant pathologist here said there is such rapid growth that the unfurling leaves tend to sometimes pop into shape making noise. I've seen the time lapse of this but no audio.

the plants themselves? I'm fairly sure I heard somewhere that the misletoe that shoots its seeds makes some kind of noise. Feb 04 05, 5:42 PM

When my lupin seed pods exploded last summer they woke me up from my slumber in the sunshine. I thought someone was throwing stones at the fence. They were certainly expelled with some force. Feb 04 05, 6:02 PM

I've heard that yarn about corn growing, cubster, and maybe calling it a lie is a little strong, but I don't see anyone calling you or your aggies a liar for perpetuating it. Kinda romantic, really. http://www.acoustics.org/press/138th/press_release.html The Sound of Corn Growing Farming legends suggest that one can hear corn growing, especially at night, with distinctive popping sounds. These popping sounds actually do occur, but David G. Browning of the University of Rhode Island attributes them to something different than suggested by legend: puffs of wind during otherwise calm conditions cause adjacent leaves to strike each other, producing in many cases a distinctive spectrum of sounds. The sound spectrum changes as the corn matures (the increased weight of the corn ears causes the stalks to sway more pronouncedly) and as it loses moisture (the leaves become more brittle). Browning says that the "sound of corn growing" can therefore be transformed from a fanciful legend into a practical tool for monitoring the condition of crops. Feb 04 05, 6:58 PM

The yellow-rattle plant makes a noise when the wind moves the seed heads. (It's quite common in the dunes near here.) Feb 05 05, 3:20 AM

The lupin seed bit sounds credible. When moisture gets on some plants, they will eject their seed pods with some force, even stinging legs as you are passing, which can make quite a racket if there is enough of them. The corn thing is a load of codswollop, they may "rustle", but this is ONLY the WIND! Feb 05 05, 8:32 AM

Several plants like gorse have an explosive mechanism for spreading their seeds. Certain plants like evening primrose pop when they open. However, the only audible noise most plants make is the rustling and cracking of other agents such as the wind pushing through them. Feb 06 05, 12:09 AM

Do any plants have glands? How do rock cactuses and other not-green plants make their own food? What is the difference between white sound or noise and brown sound and does sound come in any other "colours?" I have once heard that a noise was recorded in an American forest that matched no animal or human sound but was definately something living, does anyone know any more about this?
