cardiovascular adverse effects are interesting aspects of occupational noise exposure. one possible mechanism of these effects is an alternation in hypothalamic-pituitary-adrenal axis. our aim was to measure salivary cortisol response to relatively high-intensity noise exposure in a controlled randomized trial study. we exposed 50 male volunteers to 90 dba noise for 20 minutes and compared thei...
In this paper, we examine the effects of correlated Gaussian noise on a two-dimensional neuronal network that is locally modeled by the Rulkov map. More precisely, we study the effects of the noise correlation on the variations of the mean firing rate and the correlations among neurons versus the noise intensity. Via numerical simulations, we show that the mean firing rate can always be optimiz...
Background and aims During last decades one of the hazardous agents on workers health has been workplaces noise. The aim of this study was to investigate the level of noise exposure in different jobs and noise induced permanent threshold shift in relation to noise level and work experience. Methods This is a cross-sectional and descriptive study that performed among total workers. Dosimet...
