This set of chimes is more like a mobile of miniature garden tools. I thought I’d record them today, and see whether their sound and motion instrumented wind speed and direction.

But no, not really. The prevailing wind is from the north (to the left in the clip) but this afternoon it was gusty and shifty, as you can infer in the clip from the movement of the chimes.

You can see the wind tighten and release the tension in the mobile, just as it does the tension of the honeysuckle vines. And at the end, you hear some soft chiming.

What you really hear, though, is traffic: The rising and falling swish of passing cars. You don’t hear the wind at all, and you hear the chimes barely. But in “real” life, I don’t hear the traffic at all. Some autonomous subsystem blocks it out.
