Abstract
With few exceptions, the echo is a common phenomenon that occurs more or less during our talks. We then hear our own voice as a sound wave that bounced off the floor, walls, or other objects and returned to our ears. If the reflected sound comes back after a very short period of time, then it is perceived not as an echo, but as a kind of spectral distortion or reverberation, consisting of extending the sound. Depending on the situation, the occurrence of reverberation may or may not be desirable. When the time of arrival of reflections exceeds a certain value, it occurs as a separate sound that interferes with the reception of sound information. This paper will present methods of acoustic echo cancellation in telecommunication networks, in which parallel and distributed computing environments will be applied using multi-pass parallel algorithms based on non-recursive adaptive filtering.
