It's based on several things. My own ears, my understanding of the compression algorithms and how digital audio data works, tests I have done...
Consider a bass sine wave - let's say 100Hz. It only takes 200 samples per second to accurately reproduce. That's not very much data.
Now take an upper treble sine wave - let's say 18kHz. That takes 36,000 samples per second to reproduce. A bit more data, to say the least.
Why on earth would a compression algorithm pick apart the bass when such a small amount of data is needed for it, when there are plenty of frequencies that most people can't even hear(or are hardly present in any music in the first place) that it can pick apart a lot more for very little, if any impact at all?
And this isn't just me speculating, this is the way it works. Tested and true.
Bass isn't touched. Some very difficult to hear harmonics on cymbals and some other percussion is.
