i am aptly aware of this, in fact i'm aware of the fact that it's actually a 12db drop in volume. Someone else kindly told me what was in the article.
But my primary point is still true.
and in defense of myself, most articles are bullshit anyway. 50% of it is filler, and 20% of it is useless information, edu sites are generally better, but there's no guarantee, and i don't bother with most articles these days. And my problem here isn't even the fact that they did drop the volume of the noise, my problem is that i'm not sure this is a significant accomplishment.
There are a lot of fields actively researching this exact same concept.
