舞臺(tái)音響的作用可分為四類，即擴(kuò)音放音、氣氛營造、音響效果和協(xié)調(diào)作用。下面就讓
山東音響廠家為您具體詳述一番，如下：
The functions of stage acoustics can be divided into four categories, namely, sound amplification, atmosphere creation, sound effect and coordination. Now let Shandong professional audio manufacturers give you a detailed description, as follows:
擴(kuò)音放音作用
Amplification and playback
指利用各類音響設(shè)備，將舞臺(tái)聲音及音樂進(jìn)行擴(kuò)大。擴(kuò)音放音是舞臺(tái)音響的基本作用，只有保證擴(kuò)音放音作用的正常發(fā)揮，才能實(shí)現(xiàn)烘托舞臺(tái)氣氛的作用。
It refers to the use of various audio equipment to expand the stage sound and music. Public address and playback is the basic role of stage acoustics. Only by ensuring the normal play of public address and playback, can the role of setting off the stage atmosphere be realized.
氣氛營造作用
Atmosphere building function
指依據(jù)演出劇目的情節(jié)需要，將實(shí)際生活環(huán)境或生活狀態(tài)用聲音的形式表現(xiàn)出來，營造出一種身臨其境的藝術(shù)效果。例如，用音效模擬風(fēng)、雨、雷、電的聲音，通過表現(xiàn)大自然的各種自然現(xiàn)象實(shí)現(xiàn)營造故事氛圍、烘托人物心理的效果，使得舞臺(tái)表演更加引人入勝。
It refers to expressing the actual living environment or living state in the form of sound according to the needs of the purpose and plot of the play to create an immersive artistic effect. For example, sound effects are used to simulate the sound of wind, rain, thunder and electricity. Through the performance of various natural phenomena of nature, the effect of creating a story atmosphere and foil the characters' psychology is achieved, making the stage performance more attractive.
音響效果
Sound effect
舞臺(tái)音響的效果依據(jù)有無音源可分為兩類，即有音源音響效果和無音源音響效果。前者因采錄于自然或者生活中真實(shí)的音源而又被稱為“現(xiàn)實(shí)性效果”，后者則被稱為“非現(xiàn)實(shí)性效果”。音響效果與舞臺(tái)氣氛的圓滿展現(xiàn)息息相關(guān)。好的音響效果取決于音響師對音響設(shè)備性能和功能的掌握及使用。例如：
The effect of stage sound can be divided into two categories according to whether there is sound source or not, namely, sound effect with sound source and sound effect without sound source. The former is called "realistic effect" because it is recorded from the real sound source in nature or life, while the latter is called "non realistic effect". The sound effect is closely related to the perfect presentation of the stage atmosphere. A good sound effect depends on the sound engineer's mastery and use of the performance and functions of sound equipment. For example:
不同形式的話筒，包括講話筒、電容話筒和喉頭話筒(即領(lǐng)夾麥克)等，其發(fā)聲源位置和接受頻率均有所差異，因而接受到的音頻信號各有不同。因此，必須保證話筒與音頻信號的一一對應(yīng)，使得信號能夠被準(zhǔn)確接受及清晰表達(dá)。
Different types of microphones, including speaker microphones, condenser microphones and throat microphones (i.e. lavalier microphones), have different sound source locations and receiving frequencies, so the audio signals received are different. Therefore, the one-to-one correspondence between microphone and audio signal must be ensured so that the signal can be accurately received and clearly expressed.
再比如，演出中可能出現(xiàn)多個(gè)演員所使用的話筒接受頻率十分相近的情況，此時(shí)音響師應(yīng)當(dāng)特別注意區(qū)分避免出現(xiàn)因串頻而導(dǎo)致的混音，使演出效果大打折扣。
For another example, in the performance, the receiving frequency of microphones used by multiple actors may be very similar. At this time, the sound engineer should pay special attention to distinguish and avoid mixing caused by cross frequency, which will greatly reduce the performance effect.
協(xié)調(diào)作用
Coordination role
精彩的舞臺(tái)表演必然包含跌宕起伏的情節(jié)，因而需要舞臺(tái)音響依據(jù)劇情需要對舞臺(tái)表演的節(jié)奏進(jìn)行掌控，使情節(jié)的展現(xiàn)更加錯(cuò)落有致，更加協(xié)調(diào)。因此，舞臺(tái)音響的協(xié)調(diào)作用貫穿整個(gè)演出過程，配合劇情發(fā)展需要發(fā)揮作用。
The wonderful stage performance must contain ups and downs of the plot, so the stage sound needs to control the rhythm of the stage performance according to the plot needs, so that the plot can be displayed more orderly and coordinated. Therefore, the coordination function of stage acoustics runs through the whole performance process and plays a role in coordination with the development of the plot.
