Well it appears our ears - or at least the ears of 250 Minnesota undergrads - prefer chords containing harmonically related frequencies, according to a study in the journal Current Biology.
《当代生物》刊登的一项研究表明，原因在于我们的耳朵更喜欢某些频率的和弦——至少明尼苏达州250名大学生的耳朵有这种喜好。
We present a method for preserving time-invariant phase relationships, through introduce a third signal as a reference, when ratios are taken between two complex signals that are harmonically related.
