I was intrigued by this paragraph in the article:

>> Psychoacoustics is the study of how humans perceive sound, and it's relevant here because advocates of lossy data compression argue that when listening to CD-quality audio, it is impossible for our brains to perceive all the data reaching our ears. It is, therefore, unnecessary — the argument goes — to store and reproduce all of that data. But which data can be removed is another question, and this is why various psychoacoustic principles are exploited in different amounts by different perceptual audio coding algorithms.

I wonder if different people will perceive sound differently (in terms of frequency and dynamics) purely based on physiological/psychological traits?
