It was really easy to tell which is which for the vocals. On the other hand, the only sample in which I didn't hear ANY difference is Ennio Morricone's, to the point where I couldn't really tell it apart from its 56kbit/s version. Can the hearing be selectively bad for some frequencies within the standard 20-20000 range, and normal for the others? | ||

> Can the hearing be selectively bad for some frequencies within the standard 20-20000 range, and normal for the others? Yes. Your ears are acoustic filters just like microphones and speakers. When you get your ears tested, you get a chart that looks suspiciously like a speaker/mic response chart. Frequency in the x, db attenuation in the y. So a person with bad ears could have fine hearing below say 5 khz, but with a sharp cut-off beyond that. Or it could be any other way round. Or you could have a notch in the middle. Calibrated hearing aids just take this chart and boost the frequencies your ears are attenuating. You can eq your own sound equipment based on the chart, to get a result that compensates for your ears. | ||
