混响 Reverberation

(重定向自Reverberation level)

混响(reverberation)是声源发音停止后声音继续存在的声学现象。其产生原因在于声波的传播需要被墙壁或周围障碍物所阻碍并反射,其消失也就滞后于发声。

根据不同场合的音效需要,要考虑到混响时间的不同长短。在音乐厅或剧院等对混响敏感的场所,其建筑材料要做特殊要求。

Reverberation, in psychoacoustics and acoustics, is the persistence of sound after a sound is produced. A reverberation, or reverb, is created when a sound or signal is reflected causing a large number of reflections to build up and then decay as the sound is absorbed by the surfaces of objects in the space – which could include furniture, people, and air. This is most noticeable when the sound source stops but the reflections continue, decreasing in amplitude, until they reach zero amplitude.
