BACKGROUND Results from studies of road traffic noise and hypertension are heterogeneous with respect to effect size, effects among males and females and with respect to effects across age groups. Our objective was to further explore these associations. METHODS The study used cross-sectional public health survey data from southern Sweden, including 24,238 adults (18 - 80 years old). We used a...
OBJECTIVES To determine (i) noise exposure levels of spectators at a FIFA 2010 designated training stadium during a premier soccer league match; and (ii) changes in auditory functioning after the match. METHODS This was a one-group pretest-post-test design of football spectators attending a premier soccer league match at a designated FIFA 2010 training stadium in Gauteng, South Africa. Indivi...
There has been a growing recognition among noise researchers that natural elements and natural areas of the built environment have potentials to reduce annoyance due to traffic noise. It has been suggested that presence of vegetation (e.g., trees, bushes, grass, flowers) contributes to an aesthetically pleasing environment, which influence overall residential satisfaction and people‟s perceptio...
Annoyance, recognition and detection of noise from a single wind turbine were studied by means of a two-stage listening experiment with 50 participants with normal hearing abilities. In-situ recordings made at close distance from a 1.8-MW wind turbine operating at 22 rpm were mixed with road traffic noise, and processed to simulate indoor sound pressure levels at LAeq 40 dBA. In a first part, w...
Noise pollution is a growing problem across the world and one which many people may not be aware of impacts on their health. The environmental noise, in particular road traffic remains major affecting health well-being millions people. With this background, comprehensive ‘noise assessment study’ was undertaken for busy corridor Ahmedabad city India. spans around 22.25 km passes through mix diff...

It offers definitions right-of-way zone highlights topics that have not yet been regulated. At same time, research methods...
INTRODUCTION The aim of this study was to investigate self-reported hearing and portable music listening habits, measured hearing function and music exposure levels in Swedish adolescents. The study was divided into two parts. MATERIALS AND METHODS The first part included 280 adolescents, who were 17 years of age and focused on self-reported data on subjective hearing problems and listening h...
BACKGROUND Wind turbine noise exposure and suspected health-related effects thereof have attracted substantial attention. Various symptoms such as sleep-related problems, headache, tinnitus and vertigo have been described by subjects suspected of having been exposed to wind turbine noise. OBJECTIVE This review was conducted systematically with the purpose of identifying any reported associati...
BACKGROUND The wind turbine's sound seems to have a proportional effect on health of people living near to wind farms. This study aimed to investigate the effect of noise emitted from wind turbines on general health, sleep and annoyance among workers of manjil wind farm, Iran. MATERIALS AND METHODS A total number of 53 workers took part in this study. Based on the type of job, they were categ...
CONTEXT Distortion product otoacoustic emissions (DPOAEs) may indicate preclinical noise-induced hearing loss (NIHL) in adolescents from unsafe personal music player (PMP) use. AIMS The objective, therefore, was to observe preclinical signs of NIHL in 9th grade adolescents with clinically normal hearing by comparing DPOAE signals between different levels of A-weighted equivalent PMP exposure....
