Of course, one year's observation doesn't prove anything, but it's encouraging. And here's an intriguing report from University of Washington researchers. Falling snow seems quiet to us. But it's loud to fishes, according to acoustical scientists. A researcher at John Hopkins University explains it this way.
Snowflakes are full of air.
When they fall in water, they release the air. The water's surface tension holds down the bubbles, which vibrate in their efforts to escape, producing the screechy sound. The noise is in the range of 50 to 200 kilohertz. It's too high for us to hear, but it might be darned annoying to many species of aquatic life. That's something to think about when it's snowing over Lake Tahoe.
