电声技术在中小学合唱团表演音效制作的应用研究

Research on the Application of Electroacoustic Technology in the Production of Sound Effects of Chorus Performance in Primary and Secondary schools

电声技术的发展,使得音乐表演的效果更加突出,影响范围更大.在合唱团表演中,利用电声技术实现声音的录制和传播十分常见.中小学合唱团也需要通过先进的电声技术来实现良好的表演效果.基于此,阐述合唱中人声的频率范围、话筒的选择以及话筒摆放位置与声音层次的关系,从追求自然和谐的群感效果、合唱团表演中话筒的安装与调试、通过后期声音制作来打造优质作品等3个方面探讨电声技术在中小学合唱团表演音效制作的方式,为中小学合唱团表演的现场声音录制以及后期的作品制作提出相关的思路.

The development of electroacoustic technology makes the effect of music performance more prominent and has a wider range of influence.In chorus performance,it is very common to use electroacoustic technology to realize sound recording and transmission.Primary and secondary school choirs also need advanced electroacoustic technology to achieve good performance results.Based on this,this paper expounds the frequency range of human voice in chorus,the selection of microphone and the relationship between microphone placement and sound level,and discusses the way of electroacoustic technology in the production of sound effects in primary and secondary school chorus performance from three aspects:the pursuit of natural and harmonious group effect,the installation and debugging of microphone in chorus performance,and creating high-quality works through post sound production,Put forward relevant ideas for the live sound recording of primary and secondary school choir performance and the later production of works.
