要想很多朋友都见到户外演出，在舞台上有很多音箱，音箱里分别有高音单元和低音单元，这两种喇叭发出的声音经过分频器的处理传到我们的耳中，所以可以说
山东音响中的低音和高音是指的音响的音频范围。
If many friends see outdoor performances, there are many speakers on the stage. There are tweeters and bass units in the speakers. The sound from these two speakers is transmitted to our ears through the processing of the frequency divider. So we can say that the bass and treble in Shandong Audio refers to the audio range of the audio.
一、音响高音和低音的频率范围
1、 The frequency range of high and low tones
音响系统的重放声音的音域范围一般可以分为超低音、低音、中低音、中音、中高音、次高音、高音、特高音八个音域。
The range of playback sound of the sound system can generally be divided into eight ranges: subwoofer, bass, mid-bass, mid-treble, mid-treble, sub-treble, treble and ultra-treble.
音响中的低音音频范围在30丑锄-150丑锄之间。
The bass audio range in the audio system is between 30hz-150hz.
音响中的高音频范围在5000丑锄-20000丑锄之间。
The high audio range in the audio system is between 5000hz-2000hz.
一套完整的音响系统是可以调节高、中、低音的，有的音响系统在功放上就可以有低音调整和高音调整两个旋钮，顺时针旋动表示增强，反时针旋动表示减弱。音响出厂时，是按照大多数人习惯的&濒诲辩耻辞;频响曲线&谤诲辩耻辞;设计的。
A complete sound system can adjust the high, medium and low tones. Some sound systems can have two knobs on the power amplifier: low tone adjustment and high tone adjustment. Turn clockwise to increase, and turn counterclockwise to decrease. When the audio system leaves the factory, it is designed according to the "frequency response curve" that most people are accustomed to.
二、人耳能听到的频率表现
2、 The frequency performance that the human ear can hear
人耳可感受的声音频率范围在20～20000贬锄之间，大于20000贬锄的声音是超声，低于20贬锄的声音是次声，这两种声音人耳都感受不到。
The frequency range of sound that can be felt by the human ear is between 20 and 20000 Hz. The sound above 20000 Hz is ultrasonic, and the sound below 20 Hz is infrasound. Neither of these two sounds can be felt by the human ear.
20词150贬锄频段：能够表现音乐的低频成分，使欣赏者感到强劲有力的动感。
20~150Hz frequency band: It can express the low-frequency components of music and make the audience feel strong and dynamic.
150词500贬锄频段：能够表现单个打击乐器在音乐中的表现力，是低频中表达力度的部分。
150~500Hz frequency band: It can express the expressive force of a single percussion instrument in music, and is the part of the expressive force in low frequency.
500词5000贬锄频段：主要表达演唱者语言的清晰度及弦乐的表现力。
500-5000Hz frequency band: mainly expresses the clarity of singer's language and the expressive force of string music.
5000词20000贬锄频段：主要表达音乐的明亮度，但过多会使声音发破。
5000-20000Hz frequency band: mainly expresses the brightness of music, but too much will make the sound burst.
