The experiments presented compare the performance to PESQ and POLQA and benchmarks their performance over a range of common background noises and warp, clock drift, and jitter VoIP impairments.
A shiss, we learn, is "the increasingly common scratchy background noise that emanates from someone else's Walkman in an elevator, car or other enclosed space".
Previous experience in QTL interval mapping has indicated that it is common for "background" noise in LOD score profiles to occur in the range of LOD values between 0 and 1. Figure 3 provides an example of the usefulness of lowering the LOD detection threshold for QTL detection in the particular context of such across-experiment comparisons.
The study in [29] considers a variety of common sources of background noise in the separation algorithm, and modifies numerous pre- and post-processing algorithms in order to account for the characteristics of the background noise.
Under American occupation, the city had descended into chaos, with kidnappings common, gunfire a constant background noise, and the insurgency in its early stages.
Filtering of microarray data is common due to levels of background noise, below which gene expression cannot be accurately called.
The common limitation with microarray is high background noise interference introduced at different experimental and analysis stages.
Because low-frequency background noise is a common issue at the study site due to its proximity to the waterfalls of the Iguazú River, it was necessary to set the cutoff frequency at 800 Hz (i.e., nothing below 800 Hz was considered in calculating the acoustic parameters of the calls).
The PM has acknowledged he sometimes gets "distracted" by the amount of background noise in the Commons and that he should "try and tune out the noise and just concentrate on trying to answer the question".
Common situations are the presence of speech, a consistent background noise, increasing background noise, decreasing background noise, etc.
