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.
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.
The yellow-rattle plant makes a noise when the wind moves the seed heads. (It's quite common in the dunes near here.)

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!
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.
