Sentence examples for noise segments from inspiring English sources

Unbeknownst to the participants, five different target noise segments, which repeated within trials, also reoccurred across several trials (reference-RN, RefRN).

We used a noise-memory paradigm,29 in which participants have to detect repeating noise segments embedded within running white noise.

Background EEG was included in four test signals, modeled either as small additional sinusoids across the spindle frequency range or as filtered Gaussian noise segments.

In addition, as stimuli were randomly generated, prior exposure could be precisely controlled as the probability, for each participant, to have encountered the exact same noise segments before the experiment is close to 0. The white-noise learning paradigms provide therefore a unique opportunity to investigate the learning of novel sensory information.

A lot of noise segments are generated too.

We add the transient noise segments to the random points of time of the speech signals.

White noise being deprived of significant fluctuations in acoustic energy or salient perceptual landmarks that usually trigger ERPs (e.g., silence-to-noise transition in the case of AEPs), any deviation from the N condition for RefRN and RN trials can be interpreted as an indication that the brain had detected the presence of the repeated noise segment.

The fact that listeners could discriminate between RN and N trials demonstrates their ability to detect the reoccurrence of a nondescript noise segment embedded in running noise after only few presentations (max: 5 in the pre-sleep phase) and despite the statistical similarity between targets and fillers.

The next step is to sample an appropriate noise segment according to the noise type.

Figure 1a represents a transient noise segment which is added to speech signal.

The GIN [23] is composed of a series of 6-second segments of broadband noise containing 0 to 3 silent intervals or gaps per noise segment.
