Book excerpt: The U.S. Department of the Interior (DOI), National Park Service (NPS), and the U.S. Departmentof Transportation (DOT), Federal Aviation Administration (FAA) are jointly sponsoring a study toexamine the accuracy of existing models used for predicting tour aircraft noise in Grand CanyonNational Park (GCNP). In particular, three models will be included in the study: the NPS' NoiseOverflight Decision Support System (NODSS), the FAA's Integrated Noise Model (INM), and athird model, the Noisemap Simulation Model (NMSIM), which has been developed with fundingfrom both the U.S. Air Force and the National Aeronautics and Space Administration. A keycomponent of the GCNP Noise Model Validation Study is the collection of field data to support thevalidation effort. These field data will be translated into formats usable by the three noise predictionmodels. This common set of high quality field data will allow an unbiased comparison of the threemodels. This letter report addresses portions of the field data collection activity and associated dataanalysis.

This book was released on 2018-07-23 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Noise levels around airports and airbases in the United States arc computed via the FAA's Integrated Noise Model (INM) or the Air Force's NOISEMAP (NMAP) program. These models were originally developed for use in the vicinity of airports, at distances which encompass a day night average sound level in decibels (Ldn) of 65 dB or higher. There is increasing interest in aircraft noise at larger distances from the airport. including en-route noise. To evaluate the applicability of INM and NMAP at larger distances, a measurement program was conducted at a major air carrier airport with monitoring sites located in areas exposed to an Ldn of 55 dB and higher. Automated Radar Terminal System (ARTS) radar tracking data were obtained to provide actual flight parameters and positive identification of aircraft. Flight operations were grouped according to aircraft type. stage length, straight versus curved flight tracks, and arrival versus departure. Sound exposure levels (SEL) were computed at monitoring locations, using the INM, and compared with measured values. While individual overflight SEL data was characterized by a high variance, analysis performed on an energy-averaging basis indicates that INM and similar models can be applied to regions exposed to an Ldn of 55 dB with no loss of reliability.

This book was released on 2018-06-13 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aircraft noise measurements were made at Denver International Airport for a period of four weeks. Detailed operational information was provided by airline operators which enabled noise levels to be predicted using the FAA's Integrated Noise Model. Several thrust prediction techniques were evaluated. Measured sound exposure levels for departure operations were found to be 4 to 10 dB higher than predicted, depending on the thrust prediction technique employed. Differences between measured and predicted levels are shown to be related to atmospheric conditions present at the aircraft altitude.

Download or read book Aircraft Noise written by Oleksandr Zaporozhets and published by CRC Press. This book was released on 2011-05-13 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aircraft noise has adverse impacts on passengers, airport staff and people living near airports, it thus limits the capacity of regional and international airports throughout the world. Reducing perceived noise of aircraft involves reduction of noise at source, along the propagation path and at the receiver. Effective noise control demands highly skilled and knowledgeable engineers. This book is for them. It shows you how accurate and reliable information about aircraft noise levels can be gained by calculations using appropriate generation and propagation models, or by measurements with effective monitoring systems. It also explains how to allow for atmospheric conditions, natural and artificial topography as well as detailing necessary measurement techniques.
