The authors examined whether air pollution at school (nitrogen dioxide) is associated with poorer child cognition and health and whether adjustment for air pollution explains or moderates previously observed associations between aircraft and road traffic noise at school and children's cognition in the 2001-2003 Road Traffic and Aircraft Noise Exposure and Children's Cognition and Health (RANCH)...

In 1992, 1998, and 2006, questionnaires were sent to stratified samples of residents aged 18-75 years living near petrochemical industries (n = 600-800 people on each occasion) and in a control area (n = 200-1,000). The aims were to estimate the long-term prevalence and change over time of annoyance caused by industrial odour, industrial noise, and worries about possible health effects, and to ...

Backgrounds and Objectives: Noise in large cities is considered by the World Health Organization to be the third most hazardous type of pollution. Buses are an interesting object of study in the theme of noise pollution. They are at the same time a source of urban environmental (traffic) noise and occupational noise exposure source for drivers. The object of this study is Occupational noise exp...

This paper proposes a novel optimization framework in passive control techniques to reduce noise pollution. The geometries of the structures are represented by Catmull-Clark subdivision surfaces, which able build gap-free Computer-Aided Design models and meanwhile tackle extraordinary points that commonly encountered geometric modelling. acoustic fields simulated using isogeometric boundary ele...

Noise pollution degrades natural acoustic conditions, potentially interfering with bird communication. However, exactly how noise impacts the ability of the signal receiver to detect and discriminate vocalizations from conspecifics remains understudied in field settings. We performed a natural experiment to determine the effect of noise pollution on the territorydefense behaviors of two emberiz...

Background: Noise pollution is the third most dangerous risk factor for human health after air and water pollution. The aim of this study was to evaluate the effect of noise pollution on sleep disturbance among Neyshabur governmental teaching hospital staff, Iran, in 2015. Materials and Methods: This cross-sectional study was conducted in winter 2015. The sample size was 261 people from 2 hosp...

In this paper we present a new approach to monitor noise pollution involving citizens and built upon the notions of participatory sensing and citizen science. We enable citizens to measure their personal exposure to noise in their everyday environment by using GPS-equipped mobile phones as noise sensors. The geo-localised measures and user-generated meta-data can be automatically sent and share...

The ‘Zomig Appropriate for Primary care’ programme was developed to address the needs of primary care physicians (PCPs) to improve migraine management. As part of the programme, an international, open-label, 6-month clinical study was performed. The study included new and tangible outcome variables relevant to PCPs and recruited patients presenting in primary care with an established migraine d...
