What is the Larsen effect?


We are proud to open our sound area by introducing one of the most common problems that can occur at any sound installation. It is known as Larsen effect, also known as feedback effect. This effect is produced when a sound signal that has already been amplified and reproduced by a loudspeaker is again captured by a microphone. This cause of events creates a specific annoying sound that can be familiar to most of the people. The real problem is that due to this effect we are forced to reduce the volume level of the system and as a result its performance is decreased. In this article we will analyze the causes of this effect as well as different ways to solve it.
