Book excerpt: Low-frequency impulsive noise, characteristic of demolitions, artillery, and armor, is difficult to mitigate. In 2001, ERDC-CERL researchers were tasked to study the potential attenuation caused by a forest. After a thorough review of published work, it was determined that an experiment was necessary. This took place in July 2002 at the Lone Star Army Ammunition Plant in Texarkana, Texas. This report presents the data analysis and draws conclusions about the effectiveness of a forest stand on noise mitigation. Additionally, some predictive modeling has been performed, and those results also are included.

This book was released on 2012-12-12 with total page 591 pages. Available in PDF, EPUB and Kindle. Book excerpt: With major implications for applied physics, engineering, and the natural and social sciences, the rapidly growing area of environmental fluid dynamics focuses on the interactions of human activities, environment, and fluid motion. A landmark for the field, the two-volume Handbook of Environmental Fluid Dynamics presents the basic principles, fundamental flow processes, modeling techniques, and measurement methods used in the study of environmental motions. It also offers critical discussions of environmental sustainability related to engineering. The handbook features 81 chapters written by 135 renowned researchers from around the world. Covering environmental, policy, biological, and chemical aspects, it tackles important cross-disciplinary topics such as sustainability, ecology, pollution, micrometeorology, and limnology. Volume Two: Systems, Pollution, Modeling, and Measurements explores the interactions between engineered structures and anthropogenic activities that affect natural flows, with particular emphasis on environmental pollution. The book covers the numerical methodologies that underpin research, predictive modeling, and cyber-infrastructure developments. It also addresses practical aspects of laboratory experiments and field observations that validate quantitative predictions and help identify new phenomena and processes. As communities face existential challenges posed by climate change, rapid urbanization, and scarcity of water and energy, the study of environmental fluid dynamics becomes increasingly relevant. This volume is a valuable resource for students, researchers, and policymakers working to better understand environmental motions and how they affect and are influenced by anthropogenic activities.

This book was released on 2022-01-01 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mining refers to the process of extracting minerals and metals from the crust of the earth. Some minerals can be mined more easily as they are found on the earth’s surface, while others lie far beneath the surface and can be obtained only by digging deep underground. Gold, Silver, Diamond, Iron, Coal, Aluminum (Bauxite) and Uranium are some of the vast array of metals and minerals that are obtained by the latter process. In fact, mining is the source of all the substances that cannot be obtained by industrial processes or through agriculture. Mining, in its wider sense connotes extracting and processing of a non - renewable mineral resource. Minerals can be classified into metallic (iron, copper, gold, aluminum, uranium etc.) and non-metallic (sand, salt, phosphates etc.) These minerals are non-renewable or depleting assets and once mined-out, they are exhausted and are lost forever without any chance of replenishment. Simply, this exhaustible resource cannot be harvested, unlike agricultural products.

Download or read book Predicting Outdoor Sound written by Keith Attenborough and published by CRC Press. This book was released on 2021-03-07 with total page 690 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of Predicting Outdoor Sound is an up-to-date reference on the propagation of sound close to the ground and its prediction. New content includes comparisons between predictions and data for road traffic, railway and wind turbine noise; descriptions of source characteristics in the HARMONOISE model; propagation over rough seas, parallel low walls, and lattices; outlines of numerical methods; gabion (caged stones) and sonic crystal noise barriers; meteorological effects on noise barrier performance; and the prediction requirements for auralization. The book brings together relevant theories, prediction schemes, and data, thereby providing a basis for determining what model or scheme might be applicable for any situation. It also offers a background on useful analytical approximations and the restrictions, as well as difficulties and limitations associated with engineering prediction schemes. The text should be of considerable interest to researchers in outdoor sound propagation and, more generally, it should provide a comprehensive primer on the topic for lecturers, consultants and students in acoustics and noise control.

Download or read book Sound Recordings of Road Maintenance Equipment on the Lincoln National Forest New Mexico written by David K. Delaney and published by . This book was released on 2004 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this pilot study was to record, characterize, and quantify road maintenance activity in Mexican spotted owl (Strix occidentalis lucida) habitat to gauge potential sound level exposure for owls during road maintenance activities. We measured sound levels from three different types of road maintenance equipment (rock crusherlloader, dozerlroller, and grader), from seven distances (30,60, 120, 180,240,320, and 400 m), in two different habitat types (forested and meadow sites) on the Lincoln National Forest, New Mexico, on 22-23 October 2002 to determine how sound varied over distance, habitat type, topography, and stimulus type. Sound levels increased as the distance between road maintenance activity and microphone locations decreased, regardless of stimulus type or habitat type. Concomitantly, the amount of sound energy within the middle frequency range decreased substantially with increasing stimulus distance from microphone locations. The frequency range over which owls can potentially hear road maintenance events decreased with increasing stimulus distance. Sound recordings of road maintenance equipment were louder at tree microphones than at base microphones, regardless of stimulus distance, stimulus type, and site location. The difference in sound levels between tree and base microphones at each distance was consistently louder at meadow sites (tree microphones were located in trees along the edge of the meadow during testing at the meadow site) compared with forested sites, regardless of stimulus type or stimulus distance. Tree microphones registered a greater proportion of sound energy from road maintenance activities in the middle frequency range than at base microphones, regardless of stimulus type, stimulus distance or site location. Sound level and frequency spectra varied by stimulus type. Rock crushing equipment registered the highest sound levels of any of the road maintenance equipment tested, regardless of stimulus distance or habitat type. Rock crushing equipment had the greatest amount of sound energy in the middle frequency range of all the road maintenance equipment tested, followed by the dozerlroller and the grader, regardless of stimulus distance or habitat type. Road maintenance equipment was consistently louder than background ambient forest and meadow sound levels over a range of distances from 30 to 400 m. The extended duration of both rock crusher sound and the multiple passes required of the grader and dozerlroller are additional, potentially negative considerations. Based on our previous sound research with this species, it appears that spotted owls are capable of hearing all the sound sources tested during this pilot study out to distances of at least 400 m.
