Nocturnal environmental noise also provokes measurable biological changes in the form of a stress response, and clearly affects sleep architecture, as well as subjective sleep quality.
The results are consistent with the hypothesis that noise exposure provokes a stress response causing a release of stress hormones, which in turn affect factors such as blood pressure and heart rate and thus cardiovascular disease risk [ 21- 23].
Noise levels provoked by the integrated ventilation system were measured in close proximity to both units and were found to be identical (sound meter model 2218 with 1/3 octave filter set model 1616, Brüel & Kjaer, Naerum, Denmark).
Our study shows that freight train noise and vibration provoke HR accelerations in sleep.
Furthermore, the high chairs have the same effect as a low ceiling, subjecting diners to noise levels sufficient to provoke deep animal panic.
This just in: A European mute swan attacks jet skiers on Devil's Lake outside of rural Adrian, Mich., provoked by engine noise and protective of his five young cygnets.
Sounds, including roars, may be provoked by any loud noise.
On the other hand, noise causes an increase in signal energy provoking an artificial increase of the coded signal bit rate.
It is the aim of the present study to detect if nocturnal noise and vibration exposure from freight trains provoke HR accelerations.
Those stories catch what is so hard to capture, people's attention -- so do loud noises -- but when the noise goes away, we need reporting that engages, provokes and informs us -- not just entertains.
