Sound Pollution Due To Industries, Occupations And Municipalities Role In Managing Industries Decreasing It
Noise pollution is one of the most important features of architectural spaces having a great impact on the comfort of residents. Therefore, providing appropriate and sustainable solutions for noise pollution control is essential. Today, with the use of man-made synthetic materials, it has been tried to improve the sound performance of buildings. The purpose of this study is to show the characte...
Plants are influenced inevitably by environmental stresses due to their immobility. Sound waves are one of these environmental factors affecting plants. This study was designed to understand the relationship between sound waves and plant responses that is still low knowledge. For this purpose, Salvia splendens, one of the common plants in urban green spaces, were influenced by sound wa...

Background and purpose: Noise is one of the most harmful factors in the environment. It is also one of the harsh phenomenons in this century that people are exposed to. Exposure to noise higher than threshold limit value could cause some physical and mental disorders. High traffic flow due to recent increase in number of vehicles causes higher noise pollution. There are few studies regarding ...
OBJECTIVES Spatial assessment of traffic noise pollution intensity will provide urban planners with approximate estimation of citizens exposure to impermissible sound levels. They could identify critical noise pollution areas wherein noise barriers should be embedded. The present study aims at using the Geographic Information System (GIS) to assess spatial changes in traffic noise pollution in ...
Background and Objective: Noise pollution is an important environmental problem that may cause hazardous effects, such as hearng loss, sleep disorders, hypertension and digestive problems in communities. To prevent these effects, achieving recommended standards of noise pollution measuring in cities is mandatory. This study was aimed to evaluate noise pollution in zanjan city in 2007. Materials...
Background: Today, the effects of environmental pollution on human life and human needs, which reduces the level of community health caused by traffic noise in large cities, are clearly visible by creating irritation and pathogenic conditions. The aim of this study was to assess the risk of noise pollution resulted from central traffic in Shiraz by analyzing its indicators and related componen...
