Natural environments are increasingly exposed to high levels of noise pollution. Noise pollution can alter the behavior of animals but we know little about its effects on antipredator behavior. We therefore investigated the impact of noise pollution on vigilance behavior and roost selection in an avian species, peafowl (Pavo cristatus), that inhabits urban environments. Captive peahens were exp...
Introduction: The body's response to noise pollution is very similar to the way the body responds to stress, which can lead to poor health over time. In this regard, this study was conducted to determine the general health of the elderly and its relationship with traffic noise pollution in Ardakan. Methods: This descriptive cross-sectional study was conducted in 1399. Participants were 200...
Introduction: Safe driving requires the ability of the driver to receive the messages and complying with them. The most significant consequences of noise pollution are on the human auditory system. Disorders in the auditory system can have harmful side effects for human health. By reducing this kind of pollution in large cities, the quality of life, which is one of the biggest goals of the gove...
Introduction: exposure to noise pollution leaves Different effects on human. Goal in this Paper is the prioritizing methods of control and reduce noise pollution in Larestan cement Factory using analytical hierarchy process (AHP).

A four year long research programme divided into four phases has been designed for the first time to assess the combined Noise-Air quality and combined exposure to Noise-Air pollution at the curbside open-air microenvironment of Kolkata city, India. The results and the findings of the different phases of study had already been published. The objective of the review work is to fuse the findings ...
conclusions according to the factory noise map, except for the control rooms with 81 dba noise, other cases of measuring stations were higher than the standard exposure of 85 dba noise. as a result, the implementation of control strategies, such as inspection and performance of control systems and insulation of the control room to prevent unnecessary exposure noise, are necessary. background st...
Background and Aim: Noise is the most common source of environmental stress that influences negatively the psychological and physiological aspects of human. The purpose of this study was determining the noise sources and assessing in General Intensive Care Unit. Materials and Methods: In this cross-sectional study, equivalent noise level "Leq 15 min", Maximum and Minimum sound pressure level we...
introduction: the improvement of technology has increased noise levels in hospital wards to higher than international standard levels (35-45 db). higher noise levels than the maximum level result in patient’s instability and dissatisfaction. moreover, it will have serious negative effects on the staff’s health and the quality of their services. the purpose of this survey is to analyze the level...
BACKGROUND Evidence for an association between transportation noise and cardiovascular disease has increased; however, few studies have examined metabolic outcomes such as diabetes or accounted for environmental coexposures such as air pollution, greenness, or walkability. OBJECTIVES Because diabetes prevalence is increasing and may be on the causal pathway between noise and cardiovascular di...
