我们如何听到不同的频率范围
人的耳朵使用2個不同区别的频道來确定位置。不同的frequency會給我們不一樣的位置。如果frequency的波长小的話，波幅（amplitude）是一個很重要的因素來确定位置。如果frequency跌的話，注重力會轉于去层次（phase）。
立体感覺与频率（這個懶惰翻譯，希望BZ會諒解，有些東西翻譯了會更加不明白 ）
2,500Hz to 20,000Hz
Amplitude:
This frequency range humans detect location based on the amplified differences between channels
400Hz to 2,500Hz
Amplitude and Phase: In this frequency range we use both the amplitude differences and the phase differences to determine location. This frequency range in combination with the 100Hz to 2,500Hz frequency range is the region of human hearing that we are most sensitive. The majority of sonic information is placed within this frequency range.
100Hz to 400Hz
Phase and Amplitude: In this frequency range we also use both phase and amplitude to determine location. However, the difference between this range and the above range is the emphasis is more on phase than amplitude.
20Hz to 100Hz
Phase: In this lower frequency range we use mostly phasing cues to determine location and integration. In car audio, lower frequencies are so low that it is difficult to locate in a small environment of a car. Some say that bass is non-directional. This is true, however, the integration between the woofers and the midbass or the midrange speakers depends greatly on the phase.

向你说声谢谢，因为你为我的精华讲好话，你就要按我报告吗？
楼主
我不是很清楚邀请其他大大帮你解释一下。
