The role of stage sound effect in performance is becoming more and more prominent, and people pay more and more attention to it. How to optimize the stage sound effect is a problem that every literary and art group must consider. This paper mainly discusses how to optimize the stage sound effect from three key elements: the quality of the stage tuner, the combination of sound equipment and the integration of sound and stage environment.

一、有良好的聲音調試技術

1、 Good sound debugging technology

作為一個調音師人，我們應該對調試過的音樂作品進行深入的分析和理解，把電聲技術和聲音技術結合起來。例如，使用均衡器來改善原始聲音的音色;使用混響器和延時器增加親密度、距離和空間;你也可以使用“加倍”技術來增加某種樂器的“群體感”;特別是采用音頻數字技術后，調音師可以通過修改聲波來創造人聲和樂器的音色，并根據不同演員的聲音特點突出他們的聲音優勢，從而彌補他們聲音的不足。

As a tuner, we should deeply analyze and understand the debugged music works, and combine electroacoustic technology with sound technology. For example, an equalizer is used to improve the timbre of the original sound; Reverberators and time delayers are used to increase intimacy, distance and space; You can also use the "double" technique to increase the "group feel" of an instrument; Especially after adopting audio digital technology, the tuner can create the timbre of human voice and musical instrument by modifying the sound wave, and highlight their sound advantages according to the sound characteristics of different actors, so as to make up for their lack of sound.

二、具有良好的聲學藝術修養

2、 Have good acoustic art accomplishment

舞臺音響設備調音師要具有良好的聲學藝術素養直接影響舞臺聲音的調試效果。調音師應該熟悉不同的演員、不同的樂器以及發聲材料的振動頻率和和聲表現的差異。只有通過熟悉各種樂器和聲音的寬和窄頻帶，他才能識別聲音的特征和缺陷。如果一個歌手在舞臺上用MIDI伴奏唱歌，調音師會處理他的伴奏。同樣，與令人愉悅的舞蹈相匹配的音樂由調音師處理。這時，舞臺要求調音師將音樂的強弱對比運用到舞臺的表演中，從而達到好的表演效果。

Stage sound equipment tuner should have good acoustic artistic quality, which directly affects the debugging effect of stage sound. The tuner should be familiar with the differences of vibration frequency and harmony performance of different actors, different musical instruments and sound producing materials. Only by being familiar with the wide and narrow frequency bands of various musical instruments and sounds can he identify the characteristics and defects of sound. If a singer sings with MIDI accompaniment on stage, the tuner will handle his accompaniment. Similarly, the music that matches the delightful dance is handled by the tuner. At this time, the stage requires the tuner to apply the contrast of music strength to the stage performance, so as to achieve good performance effect.

三、具有良好的音頻調試心理素質

3、 Have good psychological quality of audio debugging

事實證明，調音師的心理素質與舞臺音響效果有很大關系，而不穩定的心理情緒會導致調音師聽覺靈敏度和分辨力的下降，甚不能正確判斷各種音色，這將對整個舞臺效果產生負面影響。

Facts have proved that the psychological quality of the tuner has a great relationship with the stage sound effect, and the unstable psychological mood will lead to the decline of the auditory sensitivity and resolution of the tuner, and even can not correctly judge all kinds of timbres, which will have a negative impact on the whole stage effect.

因此，調音師應掌握必要的心理學知識，培養較強的心理適應能力、心理承受能力和心理控制能力，靈活運用藝術心理學、創作心理學和觀眾心理學的知識，將音樂的嚴肅性和嚴肅性與音樂的幽默性有機結合起來，從而提高他在舞臺音響工作中的整體品位和水平。

Therefore, the tuner should master the necessary psychological knowledge, cultivate strong psychological adaptability, psychological endurance and psychological control ability, flexibly use the knowledge of art psychology, creative psychology and audience psychology, organically combine the seriousness and solemnity of music with the quietness of music, so as to improve his overall taste and level in stage sound work.
