How to distinguish between echo and reverberation problems?
Echo refers to: When a sound wave hits an obstacle (such as a cliff), it will bounce back and we will hear it again. This reflected sound is called echo. In the open air, the echo is blurry, because the vibration of the sound will spread around and the energy will be lost. In a confined space (such as a tunnel), the reflected sound will not run away, so the echo is very loud.
Echo refers to: Reverb usually appears in the audio system, when the original sound is picked up by the microphone (pickup) to play through the speaker and is collected again, resulting in self-excited whistle phenomenon.
How to solve?
How to solve the echo: In an open space, (such as the prison warehouse or auditorium) to solve the echo can be handled by attracting. For example, make soft packs on the walls.
Responsive solution: Acoustic echo processing can reduce the sensitivity of the pickup, using a pickup with echo cancellation function to solve. In the audio monitoring test process, the speakers and pickups can be placed in different spaces for test monitoring, or they can be opened for testing. You can also use monitoring headphones at the output for monitoring.
How to solve the problem of back stress if there is a heavy echo?
This should be called an echo and reverb, and you are echoing and reverberating. Mixing generally refers to the room. The sound energy emitted from the sound source is gradually attenuated as it is constantly absorbed by the wall surface during the propagation process. Acoustic waves are reflected back and forth in all directions, and the phenomenon of build-up attenuation is called reverberation. When the sound is reflected back from the wall more than 50 ms, the existence of two sounds can be clearly distinguished, and the echo is called. If this sound is because the distant sound reflects back, it can be divided into acoustic echoes. The reverberation process can be solved by connecting multiple pickups in series, and for acoustic echo processing, the sensitivity of the pickup can be lowered, and a pickup with an echo cancellation function can be used to solve the problem.
