我们已经知道声场中驻波是很讨厌的事,由于驻波的存在,音箱口出来的声音到听众席就完全不同了,特别是声场的均匀性受到了破坏。驻波是由于房间墙壁的反射引起的,声音的能量没有被墙壁吸收掉,反射后因相位的不同就引起声场各点不同频率的强弱不同。那么这种已发出的声音,在室内是怎样衰减掉的,不同房间都有不同,这就是混响。 We already know that the standing wave in the sound field is annoying. Due to the presence of the standing wave, the sound from the sound box is totally different from the auditorium. In particular, the uniformity of the sound field is destroyed. The standing wave is caused by the reflection of the wall of the room, the energy of the sound is not absorbed by the wall, and the different phases of the sound cause the different strengths and weaknesses of the sound field at different frequencies. So this has been made of sound, how decay indoors, different rooms have different, this is the reverb.
