要想很多朋友都見到戶外演出，在舞臺(tái)上有很多音箱，音箱里分別有高音單元和低音單元，這兩種喇叭發(fā)出的聲音經(jīng)過分頻器的處理傳到我們的耳中，所以可以說
山東音響中的低音和高音是指的音響的音頻范圍。
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、音響高音和低音的頻率范圍
1、 The frequency range of high and low tones
音響系統(tǒng)的重放聲音的音域范圍一般可以分為超低音、低音、中低音、中音、中高音、次高音、高音、特高音八個(gè)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.
音響中的低音音頻范圍在30hz-150hz之間。
The bass audio range in the audio system is between 30hz-150hz.
音響中的高音頻范圍在5000hz-20000hz之間。
The high audio range in the audio system is between 5000hz-2000hz.
一套完整的音響系統(tǒng)是可以調(diào)節(jié)高、中、低音的，有的音響系統(tǒng)在功放上就可以有低音調(diào)整和高音調(diào)整兩個(gè)旋鈕，順時(shí)針旋動(dòng)表示增強(qiáng)，反時(shí)針旋動(dòng)表示減弱。音響出廠時(shí)，是按照大多數(shù)人習(xí)慣的“頻響曲線”設(shè)計(jì)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、人耳能聽到的頻率表現(xiàn)
2、 The frequency performance that the human ear can hear
人耳可感受的聲音頻率范圍在20～20000Hz之間，大于20000Hz的聲音是超聲，低于20Hz的聲音是次聲，這兩種聲音人耳都感受不到。
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.
20~150Hz頻段：能夠表現(xiàn)音樂的低頻成分，使欣賞者感到強(qiáng)勁有力的動(dòng)感。
20~150Hz frequency band: It can express the low-frequency components of music and make the audience feel strong and dynamic.
150~500Hz頻段：能夠表現(xiàn)單個(gè)打擊樂器在音樂中的表現(xiàn)力，是低頻中表達(dá)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.
500~5000Hz頻段：主要表達(dá)演唱者語言的清晰度及弦樂的表現(xiàn)力。
500-5000Hz frequency band: mainly expresses the clarity of singer's language and the expressive force of string music.
5000~20000Hz頻段：主要表達(dá)音樂的明亮度，但過多會(huì)使聲音發(fā)破。
5000-20000Hz frequency band: mainly expresses the brightness of music, but too much will make the sound burst.
