几个常见的参数含义:

Frequency response :周波数特性(頻率響應) 正負的範圍越小越三頻均衡
Noise level, dB (A):無音状態下的雜訊分貝數,越小越好(負的數值越大越好)
Dynamic range, dB (A):動態範圍,最大音量與最小音量的分貝比數,越大越好
THD:波形的扭曲程度,請直接讀作為解析度,越小越好
THD + Noise, dB :因為波形的扭曲而產生的不該有的附帶音+雜訊,越小越好(負的數值越大越好)
IMD + Noise, % :因為波形交疊而產生的不該有的附帶音的比率+雜訊、越小越好
Stereo crosstalk, dB :左右聲道間的干涉與影響,越小越好
IMD at 10 kHz, % :因為波形交疊而產生的扭曲比率,越小越好
