There is an echo during the microphone speech at the meeting.

— During meetings, echoes from some speakers can be heard from time to time. This is, of course, related to acoustic resonance, but since air is ubiquitous, such issues have become difficult to avoid. After years of experimentation, experts both at home and abroad developed, in the early 1990s, a microphone capable of automatically suppressing echoes. However, in practice, no single microphone can completely and entirely eliminate echo on its own; it can only mitigate it. To truly eliminate echoes, complementary measures are required, and the conference system’s central control unit plays a crucial role as well.
