舞台音响的作用可分为四类，即扩音放音、气氛营造、音响效果和协调作用。下面就让
山东音响厂家为您具体详述一番，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:
扩音放音作用
Amplification and playback
指利用各类音响设备，将舞台声音及音乐进行扩大。扩音放音是舞台音响的基本作用，只有保证扩音放音作用的正常发挥，才能实现烘托舞台气氛的作用。
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.
气氛营造作用
Atmosphere building function
指依据演出剧目的情节需要，将实际生活环境或生活状态用声音的形式表现出来，营造出一种身临其境的艺术效果。例如，用音效模拟风、雨、雷、电的声音，通过表现大自然的各种自然现象实现营造故事氛围、烘托人物心理的效果，使得舞台表演更加引人入胜。
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.
音响效果
Sound effect
舞台音响的效果依据有无音源可分为两类，即有音源音响效果和无音源音响效果。前者因采录于自然或者生活中真实的音源而又被称为&濒诲辩耻辞;现实性效果&谤诲辩耻辞;，后者则被称为&濒诲辩耻辞;非现实性效果&谤诲辩耻辞;。音响效果与舞台气氛的圆满展现息息相关。好的音响效果取决于音响师对音响设备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:
不同形式的话筒，包括讲话筒、电容话筒和喉头话筒(即领夹麦克)等，其发声源位置和接受频率均有所差异，因而接受到的音频信号各有不同。因此，必须保证话筒与音频信号的一一对应，使得信号能够被准确接受及清晰表达。
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，演出中可能出现多个演员所使用的话筒接受频率十分相近的情况，此时音响师应当特别注意区分避免出现因串频而导致的混音，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.
协调作用
Coordination role
精彩的舞台表演必然包含跌宕起伏的情节，因而需要舞台音响依据剧情需要对舞台表演的节奏进行掌控，使情节的展现更加错落有致，更加协调。因此，舞台音响的协调作用贯穿整个演出过程，配合剧情发展需要发挥作用。
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.
