The present study aimed to obtain reliable, objective data on other expressions of SIHL beyond pure-tone thresholds, such as potential central auditory dysfunction and speech-in-noise difficulties.
Although blood pressure normally drops during sleep, people experiencing sleep fragmentation from noise have difficulty achieving a nadir for any length of time because blood pressure rises with noise transients and heart rate increases with noise level (Haralabidis et al. 2008).
A miniature SEE probe with a dual-clad fiber, however, had suffered from background signal from reflections within the probe optics; such high background resulted in overwhelming shot noise and difficulty at subtracting the time-varying reflections during the constant probe motion (unpublished data).
The FECG contains potentially valuable information that could assist clinicians in making more appropriate and timely decisions during labor, but the FECG signal is vulnerable to noise and difficulty of processing it accurately without significant distortion has impeded its use [ 19- 22].
When listening to music in a high-noise environment, difficulty in hearing the music and the presence of ambient noise can decrease the level of enjoyment.
In addition the difficulties with various intense noise fields, there difficulties with multi-path and multiple echoes.
However, presence of strong noise brings inherent difficulty to precise phase tracking through several dominant scatters.
Visually, the defect, particularly in Figure 19b, appears to be completely buried in noise, causing the difficulty in extracting features from this image.
We hypothesized that these individuals' failure to maintain perceptual continuity of the tone was due to some kind of interference between the neural representations of tone and the noise, leading to difficulty attending to the tone during the noise.
These capacity results were consistent across a variety of manipulations: stimuli (facing or pointing), difficulty (no noise or pink noise), viewing duration, and variability in single-sensor image placement on the screen (random or predictable).
