Noise, as the most common physical agent in workplace, not only causes hearing loss but also leads to various diseases, such as hypertension and cardiovascular disease. Sound is likely to stimulate and increase the secretion of adrenal catecholamines, and may have an indirect role in the pathogenesis of diseases caused by stress. This study was performed to investigate the effect of noise on ur...

The objective of this study was to evaluate inter-individual variability in absorbed and internal doses after multi-route exposure to drinking water contaminants (DWC) in addition to the corresponding variability in equivalent volumes of ingested water, expressed as liter-equivalents (LEQ). A multi-route PBPK model described previously was used for computing the internal dose metrics in adults,...

OBJECTIVES Spatial assessment of traffic noise pollution intensity will provide urban planners with approximate estimation of citizens exposure to impermissible sound levels. They could identify critical noise pollution areas wherein noise barriers should be embedded. The present study aims at using the Geographic Information System (GIS) to assess spatial changes in traffic noise pollution in ...

This study evaluated the impact of a participatory program to reduce noise in a neonatal intermediate care unit of a university hospital. A time-series quasi-experimental design was used, in which sound pressure levels were measured before and after the intervention was implemented using the Quest-400 dosimeter. Non-parametric statistical tests were used to compare noise with the level of signi...

The aim of the study was to determine whether or not delivery of live music poses a significant risk to the hearing of musicians involved and to evaluate current practices that are employed (if any) to protect the hearing of musicians. Method: consisted of two parts; firstly monitoring of noise exposure levels at four gigs with the application of dose meters, and secondly the completion of a qu...

Acousticians have industriously devised and refined metrics for measuring and predicting human responses to environmental noise such as sons, phons, noys, NC, NR, dB(A) dB(C), Leq, Ldn, and when rigorously applied in ISO standards offer effective reproducibility and repeatability, but they fall short when it comes to charting the vicissitudes of everyday listening and the communication of that ...
