音响效果可分为有音源音响效果与无音源音响效果两大类。有音源音响效果也可称作&濒诲辩耻辞;现实性效果&谤诲辩耻辞;。这类音响的特点在于无论是在舞台上出现或是从舞台外传来，都有其现实的可靠根据和来源。无音源音响效果又可称为&濒诲辩耻辞;非现实性效果&谤诲辩耻辞;。
Sound effects can be divided into two categories: sound effects with sound source and sound effects without sound source. Sound effect with sound source can also be called "realistic effect". The characteristic of this kind of sound is that whether it appears on the stage or comes from outside the stage, it has its realistic and reliable basis and source. Sound effect without sound source can also be called "non realistic effect".
这类音响不需要有实际的来源作为根据，而是为了侧重描绘人物的心理状态、渲染特殊气氛与情调。另外，有音源音响效果同无音源音响效果的有机结合，还可派生出混合性的音响效果。它既有现实生活的可靠来源，又有非现实的因素，两者相互转换，交替展示，用以丰富音响效果的表现情趣和手法。
This kind of sound does not need the actual source as the basis, but focuses on the description of the psychological state of the characters, and plays up the special atmosphere and sentiment. In addition, the organic combination of sound effects with and without sound sources can also derive mixed sound effects. It has both reliable sources of real life and non realistic factors, which are transformed and displayed alternately to enrich the expressive interest and technique of sound effects.
