Echo Suppression in a Computational Model of the Precedence Effect
Recent neurophysiological evidence suggests that the so-called precedence effect is a composite of multiple phenomena, in particular echo suppression and “active” mechanisms that build up and release suppression. We propose a simple functional model of echo suppression in a population of low-frequency ITD-sensitive neurons in the inferior colliculus. Our model is based on Zurek’s 1987 proposal,...
متن کاملTHE EFFECT OF ANTIHYPERTENSIVE DRUGS IN THE SUPPRESSION OF ATHEROSCLEROSIS
The present investigation was undertaken to evaluate the effect of antihypertensive drugs on aortic atherogenesis in hypercholesterolemic rabbits. In enalapril and nifedipine treated rabbits aortic atherosclerotic plaque involvement was significantly decreased (p<0. Oland p<O. 05, respectively) as compared to the control group. However, in hydrochlorothiazide treated rabbits aortic atheroge...
متن کاملInvestigation of the relationship among three common measures of precedence: fusion, localization dominance, and discrimination suppression.
Listeners have a remarkable ability to localize and identify sound sources in reverberant environments. The term "precedence effect" (PE; also known as the "Haas effect," "law of the first wavefront," and "echo suppression") refers to a group of auditory phenomena that is thought to be related to this ability. Traditionally, three measures have been used to quantify the PE: (1) Fusion: at short...
متن کاملEstimating the Delay and Coloration Effect of the Acoustic Echo Path for Low Complexity Echo Suppression
Acoustic echoes arise whenever there is acoustic coupling between a loudspeaker and a microphone. A traditional solution for eliminating the undesired echo signal is an acoustic echo canceler (AEC), which identifies the echo path between a loudspeaker and a microphone by means of an adaptive filter. The echo signal can be canceled successfully when the modeling filter approaches the true echo p...
متن کاملDNN-based residual echo suppression
Due to the limitations of power amplifiers or loudspeakers, the echo signals captured in the microphones are not in a linear relationship with the far-end signals even when the echo path is perfectly linear. The nonlinear components of the echo cannot be successfully removed by a linear acoustic echo canceller. Residual echo suppression (RES) is a technique to suppress the remained echo after a...
