High rate serial-data technologies require that receivers be tested under the stress of calibrated levels of Gaussian Random Jitter (RJ) and/or voltage noise. Every standard assumes that noise follows a Gaussian distribution with a white frequency spectrum. Several emerging standards require that stress signals used to test receivers be filtered, PCI Express Gen 2 requires two separately filter...

OBJECTIVES To identify the main causes of stress in patients staying in a coronary unit and to assess the influence of noise levels on their perception of stress. METHODS This was a prospective, descriptive and quantitative study conducted between June and November 2009 in the Coronary Unit of the Hospital de Clínicas da Universidade Estadual de Campinas. The Intensive Care Unit Environmental...

Noise is defined as a displeasing and unwanted sound. It is one of the most encountered stressor to which mankind is exposed. Frustration, poor reading, impaired hearing and difficulty in problem solving activities are the common consequences of noise stress. It has been reported to produce atrophy of dendrites and alterations in neurotransmitter levels. Long term exposure to inescapable noise ...

In spite of the existing reports on behavioural and biochemical changes related to the cerebellum due to noise stress, not much is known about the effect of noise stress on the neuronal changes in the cerebellum. The present study aims at investigating the effects from one week noise exposure on granule cell number and Purkinje cell volume within the neonate rat cerebellum. 15-day-old male Wist...

This study aims to determine the relationship between noise levels and work stress in employees of Gotri Gentong Factory Semarang. The research location working area Semarang administration production department. sample was 36 samples department administrative Analysis using chi-square test. results showed that there a meaningful intensity with prevalence value 0.000 (< 0.05). For further re...

High-intensity environmental noise is known to be detrimental cardiovascular health. However, individual differences have not been considered, and reported effects cannot generalized levels reflecting everyday life. Here, we explore the relationship between daily-life sound exposure heart rate with longitudinal data from ten individuals across three weeks. We analyze daily short-term covariatio...
