1. 混响：*混响(reverberation) 指在声学空间中的一种密集声反射,其幅度越来超低而在时间上则越来越靠近. 在音源停止发声后于室内听到的声音便是混响. *混响时间(reverberation time) 指当室内的声音的幅度减少60dB时所需的时间,用RT60表示.
2. 回响：信号源主要有潮汐、洋(河)、地壳运动、气候、冰山、生物噪音、工程、船(潜)舰、水介质相对运动、回响(Reverberation)等音源. 作战时则包括各种武器在水面或水下造成之呼啸及爆炸声;另外,海水介质受到许多自然因素的水下音响信号是藉由接收装置,
3. 残响：声音在环境中更有吸音(Absorption)、残响(Reverberation)与隔音(Insulation)等问题,也影响声学的各项效果. 高传真(High-Fidelity)简单地说就是「原音重现」,它的目的就是让听者能够体会「身历其境」的感觉,例如摇滚音乐会现场(Live)的录音,
4. 混响,交混回响：混响/交混回响(Reverberation) 在室内发出稳定的声音后,声压逐渐增长,在大多数房间内,经一秒钟后便达到稳态值. 同样,当声源停止发声后,在声音衰减到听不到以前,要经历一段时间. 声源停止发声后,声音在封闭空间反射延续的时间称为混响.
5. reverberation：rev; 残响
1. 巨大反响;重大影响;轰动
Reverberations are serious effects that follow a sudden, dramatic event.
e.g. The move by the two London colleges is sending reverberations through higher education.
