This type of echo appears when an electric signal from the data transmission line interferes with the data reception line. As a result, the given audio signal does not contain echoes anymore and can be transmitted further.The signal from the near side is subtracted from the filtered distant signal.At the same time, the signal received from a distant room is being filtered and delayed in order to look like the same signal, that got into a microphone at the nearest room.The signal is received by a microphone at the nearest room.The nearest speaker reproduces this signal.The following suppression algorithm is applied to eliminate acoustic echo: If that’s true, then Acoustic Echo Cancellation (or AEC) is a truly special kind of dark magic that the many use, but only the most talented of audio wizards truly. It’s a standing joke within the AVL industry to refer to the work of AVL integrators as the dark arts. Reflection from the elements surrounding a device. Clarity on Acoustic Echo Cancellation Operation Brings Clarity to Audio Calls.In telephony, the source of these reflections can be generated electrically due to an impedance mismatch in the transmission path or as a result of an acoustic and/or mechanical coupling between a loudspeaker and a microphone, usually because they are in the same physical enclosure. Mechanical connection between a microphone and a speaker. Echo Cancellation is the reduction of the reflected copies of a direct path wave in a signal.There are two types of regenerative coupling: That happens when the sound from the handsfree speaker enters the microphone in the same room. The acoustic echo appears due to regenerative coupling. There are two types of echo: acoustic and electric (hybrid). This process is carried out with the help of echo suppressors and echo cancellers.

Echo Cancellation is the process of removing echo from transmitted audio signals.
