Available in PDF, EPUB and Kindle. Book excerpt: The primary questions investigated in this project were: What are the atmospheric conditions in the Phoenix valley that contribute to higher than normal sound levels? Are the conditions unique to the Phoenix valley? Can the atmospheric effects be anticipated? The main components of the project were: (1) a review of literature relevant to sound propagation, (2) detailed noise measurements in a Scottsdale neighborhood along the East Loop 101 Freeway, (3) computer modeling of sound propagation under various measured and inferred atmospheric conditions, (4) noise measurements before and after installation of an asphalt rubber friction course (ARFC) on the Pima Freeway by the ADOT Quiet Pavement Pilot Program, and (5) a pilot study investigating parametric models of tire/pavement noise. Some key conclusions are: nighttime thermal inversion conditions that are common in the Phoenix valley from October through March cause sound level increases of 5 to 8 dB at distances greater than 1/4 mile from freeways, nighttime down-slope drainage flows off the mountain ranges surrounding the Phoenix valley cause localized focusing and de-focusing of sound levels, sound level variations under inversion conditions appear to be greatest at locations that are upwind relative to the down-slope flows, the highest sound levels during the October to March period will usually occur right around sunrise when high traffic volumes coincide with strong inversion conditions, and installation of the ARFC reduces sound levels by 8 to 10 dBA both close to the roadway and at distances of 1/4 mile and greater. A final tentative conclusion is that, based on the computer modeling, there may be a rapid onset of refraction effects between about 200 and 300 m (650 to 1000 ft) from Phoenix valley roadways,
Book Synopsis How Weather Affects the Noise You Hear from Highways by : Ken Kaliski
Download or read book How Weather Affects the Noise You Hear from Highways written by Ken Kaliski and published by . This book was released on 2018 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: TRB's National Cooperative Highway Research Program (NCHRP) Research Report 882: How Weather Affects the Noise You Hear from Highways documents the meteorological effects on roadway noise propagation under different atmospheric conditions. Highway noise changes from day to day and hour to hour--not just because of variations in traffic volumes, vehicle mix, and speed, but also because of the weather. The report develops guidance to identify when atmospheric conditions should or should not be considered in noise analyses.

Book Synopsis Environmental Impacts of Road Vehicles by : R M Harrison
Download or read book Environmental Impacts of Road Vehicles written by R M Harrison and published by Royal Society of Chemistry. This book was released on 2017-06-16 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first concerns that come to mind in relation to pollution from road vehicles are direct emissions of carbon dioxide and toxic air pollutants. These are, of course, important but the impacts of road traffic are altogether more substantial. This volume of the Issues in Environmental Science and Technology Series takes a broader view of the effects on the environment and human health, excluding only injury due to road traffic accidents. By looking across the environmental media, air, water and soil, and taking account also of noise pollution, the volume addresses far more than the conventional atmospheric issues. More importantly, however, it examines present and future vehicle technologies, the implications of more extensive use of batteries in electric vehicles and the consequences of recycling vehicles at the end of use. Finally, examples of life-cycle analysis as applied to road vehicles are reviewed. This book is a comprehensive source of authoritative information for students studying pollution, and for policy-makers concerned with vehicle emissions and road traffic impacts more generally.

Book Synopsis Computational Atmospheric Acoustics by : E.M. Salomons
Download or read book Computational Atmospheric Acoustics written by E.M. Salomons and published by Springer Science & Business Media. This book was released on 2001-08-31 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Noise from cars, trains, and aeroplanes can be heard at large distances from the source. Accurate predictions of the loudness of the noise require accurate computations of sound propagation in the atmosphere. This book describes models that can be used for these computations. The models take into account complex effects of the atmosphere and the ground surface on sound waves, including the effects of wind and temperature distributions, atmospheric turbulence, irregular terrain, and noise barriers. The main text of the book focuses on physical effects in atmospheric acoustics. The effects are illustrated by many numerical examples. The main text requires a very limited mathematical background from the reader; detailed mathematical descriptions of the models, developed from the basic principles of acoustics, are presented in appendices. Models for moving media are compared with models that are based on the effective sound speed approach. Both two-dimensional models and three-dimensional models are presented. As meteorological effects play an important role in atmospheric acoustics, selected topics from boundary layer meteorology and the theory of turbulence are also presented.
