This is turning into a really great discussion! I tried again to compare the samples on the HDtracks website and the 256k mp3 I bought off of amazon (I did this with every song on both DT12 and ADToE). I listened to them in 5 second snippets comparing each one closely again and, honestly, I still don't hear a lick of difference. No difference in pops or hiss or distortion of any kind on either. I compared the dynamic range my ear can discern with each instrument individually, and still, no difference.
So, this caused me to wonder again, is my hearing just bad? I am certainly guilty of listening to my music on fairly high levels often (I need to drown out the ladies at work). I haven't ever had the sonic range of my ears checked. But at the same time, I don't have a problem hearing as far as I can tell. I don't ask people to speak up or repeat themselves, I can hear high pitched things like crickets just fine, I can hear the bass guitar on the albums just fine (especially with my new earbuds).
So, being an inquisitive and stubborn person, I decided to do some research. I found these articles which approach this same issue a little more scientifically:
https://www.computeraudiophile.com/blogs/mitchco/16-44-vs-24-192-experiment-163/https://people.xiph.org/~xiphmont/demo/neil-young.htmlThe first article actually references the second but does his own experiment, both are fairly exhaustive. In a nut shell, they both claim that the human ear is not capable of discerning the differnce between 16/44 and 24/192, and any perceived difference is really all in our head. One also claims that anything above a 192k mp3 is also not discernible. I was fascinated to find that these articles conclusions were the same as my own experience. They state that the best way to get a better audio experience is not in a higher bit rate but rather in better sound equipment, which is also what I discovered after I bought my new earbuds.
But, I don't think the discussion ends here, and I certainly wouldn't call anyone, who swears there is a distinct difference, a liar. I think there might be more to our physical bodies capabilities to detect sound waves then we currently understand. For instance, I discovered a few years ago that the human heart has it's own rudimentary brain. Now, our brains are the devices that interpret the information our ears detect as audible sound, and my question is, does this rudimentary brain in our hearts have any of the same capacity? We know that sound waves vibrate through other mediums and vibrate differently depending on the medium (such as the human body). The human body has solid parts, liquid parts, soft tissues, hard tissues and empty cavities. All of these could change the way sound travels through us as individuals, and, hypothetically, could alter the way each of us perceives sound and its range. So, even if our ears cannot detect a difference, perhaps our bodies can and that information could still be transferred to and interpreted by our brains.
What do you think? Are the articles right? Or is there more to this issue?
