I very much doubt it, but let's hear from the experts here.

There's an existing thread on this on UMSF, begun 15 years ago!

I'll add that I had, by chance, a startlingly singular experience once upon a time. Visiting Utah's Arches National Monument on a very cold day, with almost no other visitors, I encountered something I did not expect and had never encountered before: Total silence. Yes, I'm sure that there was sound that a scientific instrument could have picked up, or a dog or a bat, but to my ear, it was total silence. I discovered for the first time that I could hear the sound of my neck when I turned my head. I had never noticed this before.

Why? At about 12°F, there were no insects, no birds, no other people, no airplanes flying overhead, and – in that time and place – no trees whose branches could whistle in the breeze, nor was there any snow on the ground to blow around. There was nothing to make a sound. And I had never been in that situation before, indoors or outdoors.

It seems likely that this very rare occurrence on Earth would be extremely common on other worlds. A microphone on a descending craft would pick up the sound of the wind on the microphone itself, but that is an artifact.

There are certainly phenomena on Venus, Mars, and/or Titan that would create natural sound. But it seems like a good bet that a random hour in a random location would turn up none – at least, none that a human ear would have heard.

On that..er...note, gonna shut this thread down.
