This book was released on 1982 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Federal Aviation Administration's Integrated Noise Model (INM) is a series of computer programs designed to estimate environmental noise levels in the vicinity of an airport. As part of the effort's to validate INM outputs for the FAA, comparisons were made between the Sound Exposure Levels (SEL) of actual aircraft flyovers at Seattle-Tacoma International Airport and SELs which were computed by the INM for identical conditions. Data for this analysis were obtained from the FAA ARTS-III radar to determine the actual slant range and velocity of observed aircraft, and from noise monitors located beyond each runway end to determine actual SEL values associated with observed aircraft. The report presents the results of the comparison of INM and observed SEL values for seven transport-category aircraft.

This book was released on 2014-06-19 with total page 46 pages. Available in PDF, EPUB and Kindle. 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.

Book Synopsis Validation of Aircraft Noise Models at Lower Levels of Exposure by : National Aeronautics and Space Administration (NASA)
Download or read book Validation of Aircraft Noise Models at Lower Levels of Exposure written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. 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.

Book Synopsis Validation of Aircraft Noise Prediction Models at Low Levels of Exposure by : National Aeronautics and Space Administration (NASA)
Download or read book Validation of Aircraft Noise Prediction Models at Low Levels of Exposure written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-06-13 with total page 102 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.

ARTS-III radar data were used to determine actual altitude and velocities of aircraft at various distances from the runway during arrival and departure operations. This report presents the results of the comparison.
Book Synopsis FAA integrated noise model user's guide by : Peter A. Mansbach
Download or read book FAA integrated noise model user's guide written by Peter A. Mansbach and published by . This book was released on 1976 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: The FAA Integrated Noise Model (INM) provides a conceptually simple method for characterizing aircraft noise near airports. It includes a determination of the total time that the sound level exceeds six different thresholds, and also the equivalent A-weighted sound level, L sub eq, and the day-night average sound level, L sub dn, at a number of points surrounding a particular airport. Evening and nighttime exposures are broken out separately. Thus, several methodologies are integrated into a single model which provides a very complete picture of the noise environment. The computer program INMPROG is available to calculate all of the above information and to present it in tabular form. Plotter output is also generated, for contours of equal exposures to levels above 85 dBA. Equal L sub dn contours may be produced instead, at the user's option. This manual is intended to guide the user of the model through the preparation of data required by this program. A description of the airport and its operations must be assembled onto data forms. A separate chapter specifies the punched card formats, so that the punching of cards is distinct from the collection of data. Technical appendices provide the information required for a computer center to bring up and run the program. (Author).

This book was released on 2018-06-04 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The FAA's Integrated Noise Model (INM) relies on the methods of the SAE AIR-1845 'Procedure for the Calculation of Airplane Noise in the Vicinity of Airports' issued in 1986. Simplifying assumptions for aerodynamics and noise calculation were made in the SAE standard and the INM based on the limited computing power commonly available then. The key objectives of this study are 1) to test some of those assumptions against Boeing source data, and 2) to automate the manufacturer's methods of data development to enable the maintenance of a consistent INM database over time. These new automated tools were used to generate INM database submissions for six airplane types :737-700 (CFM56-7 24K), 767-400ER (CF6-80C2BF), 777-300 (Trent 892), 717-200 (BR7 15), 757-300 (RR535E4B), and the 737-800 (CFM56-7 26K).Shepherd, Kevin P.
