What is the right time to enter a GD to ensure that I am heard properly?

During any GD, there are peaks and dips in the conversation. When the noise level reaches its maximum, it is called the crest. When you’re in the trough, there’s virtually no sound. The best time to join the GD is at the dip. In competitive GDs, however, crests are more common and troughs are less common. In such circumstances, you may recognize the phases in the GD when concepts that are important to you are being discussed and enter the GD regardless of the degree of noise.
