Nonlinear Acoustic Echo Cancellation using Voltage and Current Feedback
, 2015 Acoustic echo cancellation (AEC) is a well-studied problem. The underlying assumption in most echo cancellation solutions is that the echo path following the reference signal is completely linear.

Engineering Reports, Volume 8, Issue 6, June 2026.This study proposes an elastic wave reverse time migration (RTM) method to suppress multiple scattering noise in heterogeneous concrete. By effectively utilizing scattered wavefields, RTM enables high‐precision, robust imaging of sleeve grouting defects in prefabricated buildings, significantly outperforming traditional algorithms.

International Journal of Information and Communication Technology Research, 2009 Stereophonic acoustic echo cancellers are being used in high quality audio communication systems to reduce the echoes that arise from coupling between the loudspeakers and microphones. These echo cancellers have problems more severe than their monophonic

Acoustic Echo Cancellation Using Adaptive Least Mean Square Algorithm
, 2010 In telephony system, the received signal by the loudspeaker, is reverberated through the environment and picked up by the microphone. It is called an echo signal. This is in the form of time delayed and attenuated image of original speech signal, and

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract The vertical shear of horizontal neutral winds plays an important role in forming dense metallic layers in the E region. Previous studies suggest that metal ion layers may inhibit equatorial plasma bubble (EPB) development by enhancing E‐region Pedersen conductivity.

Stereo Acoustic Echo Control Using A Simplified Echo Path Model [PDF]
In handsfree tele- or video-communication, acoustic echoes arise due to the coupling between the loudspeakers and microphones. It is much more challenging to remove the undesired acoustic echoes for stereo or multi-channel tele-communication systems than

Speech Neurophysiology in Realistic Contexts: Big Hype or Big Leap?
European Journal of Neuroscience, Volume 63, Issue 12, June 2026.Speech neurophysiology is moving from controlled listening tasks to dynamic, socially rich interactions, challenging traditional methods. This shift promises deeper insights into how the brain processes and represents speech in real‐world contexts, while introducing new analytical complexities.

Journal of Applied Social Psychology, Volume 56, Issue 6, Page 475-492, June 2026.ABSTRACT Team creativity is central to organizational success and relies on the open exchange and integration of diverse ideas, a process known as information elaboration. Yet, the differences members naturally bring to their team can sometimes impair effective team functioning and hinder creativity.
