聆听音乐节目时,希望低音丰满,中音明亮、高音清晰透亮,使其接近实际演奏的效果。如把音量关小,则会明显地感到低音和高音不足,内容单调。原因是人耳对各个频率的敏感度的不一致。人耳感觉是一种等响度曲线。如图1所示。表征了人对声振幅的生理和心理效果。 Listening to music shows, you want the bass to be full, the tenor bright and the treble clear and translucent to bring it closer to the actual performance. If the volume is turned off, you will obviously feel inadequate bass and treble, monotonous content. The reason is that the sensitivity of the human ear to each frequency is inconsistent. Human ear feeling is a kind of equal loudness curve. As shown in Figure 1. Characterization of the physiological amplitude of the human voice and psychological effects.
