That's not what the article says. It's saying there were meaningless characters in the set of encrypted characters (which was not 1:1 with letters, but some corresponded to whole words, or vowels).

Nothing in the article says the characters were added "before encryption". The encryption wasn't a block cipher or anything like that, what you're claiming would have had no effect.

The Atlantic - Is Noise Pollution Making Desert Bugs Disappear?

> Some bug groups did not show much difference in abundance regardless of the overall noise level or the presence of a compressor. But others had dramatic changes. There were 24-percent fewer grasshoppers in compressor plots, 52-percent fewer froghoppers, and a whopping 95-percent fewer cave, camel, and spider crickets. The louder the plot was, regardless of the presence or absence of a compressor, the fewer velvet ants and wolf spiders there were.

My point was we're horrible at predicting the consequences of our own actions yet we're prepared to introduce constant low-grade sonic thumps as long as humans consider them tolerable. Seems like another great recipe for finding out in 20 years that constant low-grade sonic thumps really screw with other animals. See sonar and whales.

I find it very short-sighted that stuff like this is only concerned with human's perception and not the rest of the biosphere. How would the noise of regular flights affect animals and insects? Some animals have far more sensitive hearing than we do, and sound is energy, so a sonic shockwave is transferring energy to all those tiny bugs in a way that nature has ever had (on a regular basis) which cannot be good for their delicate structure.

Yet all we ever check is how humans feel about it. Meanwhile wildlife populations are down 69% since 1970 and insect populations are down 75% in 25 years. But hey, faster air travel!
