第一次，我也错了。然后，我阅读了博客中的所有评论，第二次听了，但仍然听不到差异。然后，我第三次听了他们的话，这次将我的头完全放在我的东芝2笔记本电脑扬声器的中心 - 然后变得很明显。第一轨的清晰度几乎稍微不高，但更重要的是它具有“深度”，而第二条曲目则没有。
就我而言，我有明确的听力损失 - 我已经受到耳朵医生的测试，并得到了很多漂亮的图表和报告。我几乎无法听到12kHz以上的声音。(in case you ever think of having professional testing done to your own ears, don’t — it’s quite expensive and if I had known I wouldn’t have done it — but that’s another story) A few things the doctor told me that are well known in this is a) most of the population suffers hearing loss as they age, the older you get the more you lose b) hearing loss isn’t even in each ear, usually one ear is worse than the other c) high frequencies go first and it becomes very hard to discriminate as the level of background noise goes up.
因此，如果您35岁以上并且您听这些剪辑，那么您根本无法通过收听Cymbals和高频声音差异来听到差异 - 从物理上看，您听不到它们。但是，您可以告诉您是否聆听每个剪辑的整体声音。其次，如果您不训练耳朵听到差异，那么您将无法。
我发现自己很有趣的一件事是，潜意识的头脑在听力时使用了大量技巧。除了大脑所做的每只耳朵中不同体积水平之间的自动平衡补偿外，我发现的另一件事也关注记忆 - 潜意识将代替您知道您应该从记忆中听到的内容。An easy way to see this is if your older, take a CD that you listened to just a few tracks on when you were young and have them memorized but haven’t listened to in years and play it in a public area where your conscious mind is partly distracted. You will notice that the tracks you have memorized on the CD sound a lot better than the tracks on the CD that you never originally listened to. Your subconscious is filling in what you can’t hear anymore with what it has in memory. It can’t do that with the tracks you never memorized so those sound duller — unless you bring your full conscious attention to all the tracks.
因此，我怀疑，如果您有音乐库，并且您会听很多音乐，并且部分收听CD或其他无损录音，那么如果您慢跑的话，您很可能会不在乎您是否会关心或其他任何东西，因为您的大脑会用记忆中的内容代替缺失的声音。但是，如果您从未听过无损版本，那么我怀疑比特率录音中的缺陷将被放大。
听力似乎是潜意识进行大量预处理以帮助有意识的思维解释声音的领域。I’m sure this goes back millions of years where the subconscious would string together a bunch of random sounds — a snap of a stick here, a leaf rustle there — and fill in the blanks, so the conscious mind would hear this and think “I better scam I hear a tiger sneaking up on me”
