In recent decades, population growth and progress of technology have shaped large and compact urban settlements. Existence of huge transportation systems and developed urban infrastructures are among the most important properties of modern cities. In spite of prompt transit and facilitated daily activities, development of transportation systems causes many problems, including traffic, air and n...

Noise pollution of roads can propagate within a broader extent than the road only. This spatial space is called "road ecological effect zone" which is known as the natural areas exposed by 40 dB or greater noise level in both sides of the road. In this study, using Calculation of Road Traffic Noise (CRTN) model, the propagation range of noise from Lorestan road network was simulated. Then, the ...

Background & Aims of the Study:  One of the most important harmful factors in big cities is noise, and traffic is regarded as the most important source of noise pollution. Therefore, this study aimed to investigate the level of knowledge, attitude, and practice of people in Kermanshah, Iran, regarding the potential effects of noise pollution on their health. Materials and Methods: A researc...

The relationships between road and rail traffic noise with pre-ejection period (PEP) and with respiratory sinus arrhythmia (RSA) during sleep, as indices of cardiac sympathetic and parasympathetic nervous system tone, were investigated in the field (36 subjects, with 188 and 192 valid subject nights for PEP and RSA, respectively). Two analyses were conducted. The first analysis investigated the...

The traffic spectra influence on indoor noise through windows is evaluated with laboratory and field measurements. Different traffic noise spectra were registered and reproduced, simulating the outdoor traffic conditions through different windows. Spectrum adaptation terms for the recorded spectra were different from the ones obtained from the Standards, showing that Normative gives a safe eval...

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 ...
