The increasing number and size of wind farms call for more data on human response to wind turbine noise, so that a generalized dose-response relationship can be modeled and possible adverse health effects avoided. This paper reports the results of a 2007 field study in The Netherlands with 725 respondents. A dose-response relationship between calculated A-weighted sound pressure levels and repo...

We have studied sidebranching induced by fluctuations in dendritic growth. The amplitude of sidebranching induced by internal (equilibrium) concentration fluctuations in the case of solidification with solutal diffusion is computed. This amplitude turns out to be significantly smaller than values reported in previous experiments. The effects of other possible sources of fluctuations (of an exte...

Railways are an environmentally friendly means of transport that offer many advantages for sustainable development. However, noise and vibration remain a major reason for objections to new lines or network expansions. Railways will never be silent but, it is nevertheless important to reduce their noise and vibration as much as possible while not adding unnecessary cost or complication to their ...

The presence of subjective tinnitus is an important aspect in the evaluation of hearing loss induced by noise. Tinnitus due to this condition is characterised by a frequency of 3,000 Hz or above and is closely related to the frequency range of maximal hearing loss. Tinnitus below 1,000 Hz is not induced by noise, and indicates the presence of a different cause for the hearing loss. This type of...

background and aim : the quick speech in noise (q-sin) test have been designed to evalu­ate individuals’ ability to recognize speech in noise. this study established to evaluate the test-retest reliability and equivalency of the five test lists of the persian q-sin test in subjects with sensory hearing loss (shl) and normal hearing individuals. methods : this cross-sectional study was per­forme...

AIMS AND OBJECTIVES To identify and compare hearing protection interventions for youth working and living on farms. BACKGROUND Noise-induced hearing loss represents a significant risk factor for injury, disability and death in agricultural populations due to an inability to receive sensory information that can indicate dangerous situations. Despite the availability of hearing protection devic...

background: noise pollution has a particular importance in quiet environments such as hospitals. the main objective of this study was to evaluate the effects of noise exposure on the auditory system, blood pressure and precision, concentration and other psycho-neural components. methods: this cross-sectional study was carried out in three large hospitals of shiraz, during the period of 2012 to ...

conclusions the effect of coadministration of nac and coq10 was neither additive nor synergic in protecting against nihl. results the temporary hearing changes that occurred 1-day post exposure were not significantly different in all groups (p > 0.05). the total recovery (between 1 - 21 days after noise exposure) varied by a frequency increase between 1.08 - 19.10 in the noise group compared to...
