In this mixed environ ment humans can easily detect frequencies as fine as one twelfth of an octave—a half step in musical terminology.
于是,在混合的声音环境中,人类能够听得到的声音频率能够精细到一个八度音阶的12分之1,即音乐术语中的半音(此处感谢Zakk指教)。
Almost all musical systems are based on scales spanning an octave-the note that sounds the same as the one you started off with, but at a higher or lower pitch.
几乎所有的音乐体系都是基于所跨越的八度音阶范围——这一音符的发音同开始时的完全一样,只是音高或高或低。
If we wanted to enlarge the original square (to find an outer square) we would again follow the natural law of the musical octave, ie powers of 2.
如果我们想扩大原广场(寻找外部平方米),我们将再次跟随音乐八度音,2即自然法的权力。
