本文简要地阐述混响室、板式混响器(钢板混响器,金箔混响器),弹簧混响器,电子混响器(模拟式和数字式电子混响器)等工作原理。对其混响声的主要特性参量:混响时间T_(60)及混响时间频率特性T_(60)-f;初次反射声的延迟时间及其与频率的关系;简正频率密度,反射声密度以及各自混响声的音色主观评价进行了比较分析,指出各种人工混响装置的特色. 最后,对人工混响装置在模拟厅堂及各种环境(包括某些特殊效果)中对不同声源进行声加工时应选取的特性参量以及人工混响装置的选取提出了参考意见。 总之,根据不同节目内容和特点,合理地选取人工混响装置及其特性参量对提高声音的技术质量和艺术质量是十分重要的。
This article briefly describes how reverb chambers, plate reverbs (steel reverbs, gold reverbs), spring reverbs, electronic reverbs (analog and digital reverbs) work. The main characteristics of its reverberation sound parameters: reverberation time T_ (60) and reverberation time frequency characteristics T_ (60) -f; the initial reflection of the sound delay time and its relationship with the frequency; simple frequency density, reflected sound density As well as the subjective evaluation of their reverb sound, and points out the characteristics of various artificial reverb devices.Finally, the artificial reverberation device is used to simulate different sound sources in the simulation halls and various environments (including some special effects) Sound processing should be selected when the characteristics of parameters and artificial reverberation device selection for reference. In short, according to different program content and characteristics, reasonable selection of artificial reverberation device and its characteristic parameters are very important to improve the technical quality and the quality of sound.
