声源与声场空间的相互关系以及其对录音的实际意义

The Relationship between Sound Source and Sound Field Space and Its Practical Significance to Recording

在现代录音中,空间和声源往往是被同时考虑的因素,发声体脱离不了所处的空间,因此我们常见的声音往往都是由直达声和反射声一起构成。本文通过阐述音源的特性与直达声、声场空间的特性与反射声和混响声、声源在声场空间中的特性、音源在不同的声场中变化等方面,结合常见的现场录音和录音棚录音等现代录音方式,探求音源与声场空间对录音的实际意义。

In modern recording, space and sound source are oftenconsidered at the same time. Voice cannot escape from space, soour common sounds are often made up of direct sounds and re-flections. This paper describes the properties of sound source anddirect sound, the properties of sound field space and reflectionsand reverberation, the properties of sound source in sound fieldspace, the change of sound source in different sound fields, andcombined with common modern ways of recording such as fieldrecording and studio recording, it explores the practical signifi-cance of sound source and sound field space to recording.
