Question: Most people can't hear beyond 15 Khz, especially people of age 25 and onwards. Then why bothering more than 128 kbps mp3 quality? Because 128 kbps cut-off all frequencies after 16 Khz. Why people are so crazy for 320 kbps mp3, which cut-off after 22 Khz? Rarely there are people, who can listen beyond 20 Khz, even let say, 18 Khz.

    mp3 at 128kbps is also often perceptibly lossy in lower frequencies. So people are into higher bitrates not just for higher frequencies, but for improved perceived quality all around.
