The performance of an echo canceller is measured in echo return loss enhancement (ERLE), [3] [9] which is the amount of additional signal loss applied by the echo canceller. Most echo cancellers are able to apply 18 to 35 dB ERLE. The total signal loss of the echo (ACOM) is the sum of the ERL and ERLE. [9] [10]
The ERN is a sharp negative going signal which begins about the same time an incorrect motor response begins, (response locked event-related potential), and typically peaks from 80 to 150 milliseconds (ms) after the erroneous response begins (or 40–80 ms after the onset of electromyographic activity).
[7] [11] This increase in amplitude has been hypothesized as the mental need to control incorrect response preparation. Latency is correlated with response time in the flanker task. [1] Although the N200 is primarily distributed over anterior brain regions, posterior distributions have been reported in visual attention paradigms, such as visual ...
Three of the most studied attributes of the N170 include manipulations of face inversion, facial race, and emotional expressions. It has been established that inverted faces (i.e., those presented upside-down) are more difficult to perceive [13] (the Thatcher effect is a good illustration of this).
Adaptive feedback cancellation originated during the evolution of the hearing aid. The hearing aid became digital, and as such feedback cancellation was needed. In 1980 a directional microphone was introduced in the digital hearing aid, and adaptive feedback cancellation was created to block external noise that the microphone picked up. Today ...
The P3b has been a prominent tool used to study cognitive processes, especially psychology research on information processing. Generally speaking, improbable events will elicit a P3b, and the less probable the event, the larger the P3b amplitude. [10] This was shown to be true both for the overall probability and for the local probability. [2]
Psychoacoustics is the branch of psychophysics involving the scientific study of the perception of sound by the human auditory system.It is the branch of science studying the psychological responses associated with sound including noise, speech, and music.
Latency, from a general point of view, is a time delay between the cause and the effect of some physical change in the system being observed. Lag, as it is known in gaming circles, refers to the latency between the input to a simulation and the visual or auditory response, often occurring because of network delay in online games.
