With constantly updated audio equipment, the system of continuous improvement, now whether it is purchased or leased to the sound, almost every stage of a stereo reverb systems are indispensable in the peripheral equipment. Add reverb can make the sound becomes more real, full but not dry, so that the activities planned to achieve the desired effect of the state. In particular, the processing in the human voice, is almost indispensable. However, adding reverb and other audio effects and processing, we must stop, before quantity, plus the place, the stage set up the position placed unreasonable time, you can continue to add or other treatment to compensate, if added too much music will become a mass of chaos seriously affect the sound clarity and understanding of the degree, if activities at the opening ceremony, and so is this phenomenon must not be allowed, so the stage lighting design, how we can use to better use what we have to look into. Here are some commonly used debugging reverb parameters.
The definition of the reverberation sound equipment: indoor sound source stops, due to the room side of the interface or one of several obstacles to sound reflection or scattering phenomena arising from the continuation of the sound. Propagation of sound in the room, to be hoof wall, ceiling, floor and other obstructions reflection, reflection time each obstacle must be absorbed by some. In this way, stop sounding when the sound source stops, the sound in the room to go through multiple reflections and absorption, and finally disappear, we feel that sound after the sound source stops also continue for some time. This phenomenon is called reverberation, this time called the reverberation time.
Reverberation time: that the parameters of the sound level of the amount of reverberation, the sound field when the room reaches a steady state sound source stops, the sound pressure level of 60dB to reduce the time required is called the reverberation time, recorded as T60 or RT, units second (s). Stage sound reverberation time is the sound design can quantitatively estimate the importance of evaluation. Accounting for the effect of a direct impact on auditorium acoustics.
Pre-delay: set up the stage when the first generation of whispering gallery - group reflected sound or reverberation time before the start. A longer pre-delay time will give a huge sense of acoustic space.
Decay time: Adjust the rear reverberation decay to hear when the elapsed time.
Early reflection scattering degree: some reflections density reverberation effect a parameter value. Refers to the irregular reflection of sound, the more irregular the shape of space, the greater the degree of scattering of sound, reflected sound, the more the closer relative to the ear, the reverberation is kept one of the sound is very modest: rather the shape of space The more rules, reflecting the emergence of more regular sound, the sound of the scattering degree of the smaller, less reflected sound, the interval between the more open, relatively close to the reverberant sound echo, the sound is very clear.
The adjustment of several parameters above, we basically can simulate any environment, any reverb.
