复数： kilohertz

But why sample at an odd number like 44.1 kilohertz ?

但是为什么要采集这个奇怪的44.1千赫频率的声音呢？

One megahertz is the same as one thousand kilohertz .

作为一个兆赫是一千千赫相同。

Radio station frequencies are often given in terms of kilohertz .

电台的频率常常以千赫为单位。

That was partly because it comfortably exceeded the nyquist minimum ( 40 kilohertz ) , but mainly because sony found it handy to do so while developing the cd with philips .

部分是由于它很轻易地优于奈奎特准则的最低值（40千赫），但是主要是因为索尼公司发现，如果同时与菲利浦开发cd的话，这个很容易做到。

Thus , an audio cd is traditionally made by sampling the analogue sound in the studio at 44.1 kilohertz , to ensure that the digital recording can reproduce the 20-kilohertz sounds at the upper end of human hearing with reasonable fidelity .

因此，传统音乐cd的制作是，通过在录音室采集模拟44.1千赫频率的声音，确保这个数字录音以合理的保真度，在人体听觉的上端重现20千赫频率的声音。
