混响是音质评价的重要指标之一。混响时间是声源停止发声后,声级减小60dB所需的时间。不同的听音房间有不同的最佳混响时间。对语言、轻音乐,要求混响时间稍短,否则清晰度不良。对于古典音乐,要求混响时间稍长些,以增加色彩。混响过多,主音不实,产生混浊感,混响过少,使声音干、扁、无彩色。一 Reverb is one of the important indicators of the quality evaluation. The reverberation time is the time it takes for the sound level to decrease by 60 dB after the sound source stops sounding. Different listening rooms have different best reverberation time. On the language, light music, reverberation time required slightly shorter, or poor clarity. For classical music, the reverberation time is longer, to increase the color. Reverberation too much, the tonic is not real, resulting in a sense of opacity, reverberation too little, the sound dry, flat, no color. one
