This book was released on 2018-06-27 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: The FAA's Integrated Noise Model (INM) is widely used to estimate noise in the vicinity of airports. This study supports the development of standards by which the fleet data in the INM can be updated. A comparison of weather corrections to noise data using INM Spectral Classes is made with the Boeing integrated method. The INM spectral class method is shown to work well, capturing noise level differences due to weather especially at long distances. Two studies conducted at the Denver International Airport are included in the appendices. The two studies adopted different approaches to modeling flight operations at the airport. When compared to the original, year 2000, results, it is apparent that changes made to the INM in terms of modeling processes and databases have resulted in improved agreement between predicted and measured noise levels.

Book Synopsis A Guide To U.S. Aircraft Noise Regulatory Policy by : Sanford Fidell
Download or read book A Guide To U.S. Aircraft Noise Regulatory Policy written by Sanford Fidell and published by Springer Nature. This book was released on 2020-07-03 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aviation noise remains the primary hindrance to expansion of airport and airspace capacity in the United States. This book describes the development and practice of U.S. aircraft noise regulation, as well as the practical consequences of regulatory policy. Starting in the pre-jet transport era, the book traces the development of the modern framework for characterizing, standardizing, predicting, disclosing, and mitigating aircraft noise and its effects on airport-vicinity communities. Among other matters, the book treats noise-related consequences of the 1978 deregulation of the airline industry; prediction and mitigation of community reaction to airport noise; land use compatibility planning; recent research and industry trends; and some suggestions for potential improvements to current policy. Initial chapters describe the assumptions underlying aircraft noise regulation, and lay out the chronology of U.S. aircraft noise regulatory practice. Later chapters provide overviews of population-level effects of aviation noise, including health effects, speech and sleep interference, and annoyance. Readers will learn why predictions of the prevalence of aircraft noise-induced annoyance have systematically underestimated adverse community response to aircraft noise, and how such underestimation has complicated approval and funding of airport and airspace improvement projects. They will also learn why attempts at noise-compatible land use planning are seldom fully successful.

Available in PDF, EPUB and Kindle. Book excerpt: This guidebook should be of interest to airport managers and other staff from airports of all sizes who are responsible for responding to neighboring communities regarding aircraft noise issues. It provides guidance on how best to improve communications with the public about issues related to aircraft noise exposure. Specifically, the guidebook presents best practices that characterize an effective communications program and provides basic information about noise and its abatement to assist in responding to public inquiries. It also suggests tools useful to initiate a new or upgrade an existing program of communication with public and private stakeholders about noise issues. An accompanying CD-ROM contains a toolkit with examples of material that has been successfully used to communicate information about noise, as well as numerous guidance documents about noise and communications that have seldom been brought together in the same resource.
Book Synopsis Meteorological Reanalysis Data Inputs for Improved Aviation Noise Modeling by : Rachel Romond

Available in PDF, EPUB and Kindle. Book excerpt: To improve the prediction capabilities of aviation noise modeling tools, recent work has focused on including the vertical structure of the inhomogeneous propagation environment. Vertical profiles of interest are temperature, pressure, humidity, wind speed, and wind direction. Previous studies have used profiles from atmospheric soundings, which are limited to the time and place at which the measurements were made. If profiles are not available for a given location, assumptions must be made about the atmospheric structure. In addition, propagation modeling based on individual soundings or standard profile assumptions may be misinterpreted to imply a simple and/or unchanging atmosphere in cases where the actual atmosphere has much greater spatial and temporal variability. An alternate source of atmospheric data is meteorological reanalysis. Reanalysis feeds quality-controlled measurements from many sources into dynamic meteorological models. These models produce 4-D data fields describing the state of the atmosphere through time. Multiple global and continent-scale reanalysis products are produced and maintained by governmental institutions, and are freely available to the public. In this dissertation, the National Centers for Environmental Prediction (NCEP) Climate Forecast System Reanalysis (CFSR) is considered for use in the calculation of noise propagation from civil aircraft at en-route altitudes to receivers near the ground. Atmospheric profiles are extracted from CFSR data and input to the Advanced En-Route Noise Model (AERNOM) acoustic ray tracing program to show the effects of realistic inhomogeneous atmospheric conditions throughout the propagation path. It is demonstrated that the CFSR 6-hourly analysis product is a feasible data source for atmospheric profiles when calculating sound propagation from in-flight aircraft. Furthermore, calculated sound pressure levels at ground receivers show that realistic vertical profiles are increasingly important as aircraft source altitude increases. The techniques described for CFSR should also be applicable to similar reanalysis products, and would be useful in future development of the Federal Aviation Administration's Aviation Environmental Design Tool (AEDT) for en-route flight altitudes.

This book was released on 2003-12-18 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: As recently as the summer of 2001, many travelers were dreading air transportation because of extensive delays associated with undercapacity of the system. That all changed on 9/11, and demand for air transportation has not yet returned to peak levels. Most U.S. airlines continue to struggle for survival, and some have filed for bankruptcy. The situation makes it difficult to argue that strong action is urgently needed to avert a crisis of undercapacity in the air transportation system. This report assesses the visions and goals for U.S. civil aviation and technology goals for the year 2050.

Book Synopsis Using High-Fidelity Weather Data to Improve Impedance and Absorption Adjustment Values in Airport Noise Level Predictions by : Emma Shaw
Download or read book Using High-Fidelity Weather Data to Improve Impedance and Absorption Adjustment Values in Airport Noise Level Predictions written by Emma Shaw and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The acoustics of an atmosphere relies heavily on environmental factors and the makeup of the atmosphere itself. It has been theorized that the integration of improved high-fidelity weather data may positively affect the prediction and modeling of outdoor noise levels, especially in large scales, such as in the field of aircraft noise. Most formal noise prediction programs currently default to assuming atmospheric homogeneity and the use of high-fidelity weather data would align more closely to the reality of the airport weather. These high-fidelity sets can be used to calculate more complex corrective adjustments corresponding to the acoustic impedance and atmospheric absorption of the region surrounding airports. This thesis will offer insight into whether or not these noise modeling programs will benefit from the use of high-fidelity meteorological files and how the accuracy of future aircraft noise predictions might be affected. The results show that the atmospheric absorption adjustment is more profoundly affected than the acoustic impedance adjustment when atmospheric inhomogeneity is incorporated.
