Available in PDF, EPUB and Kindle. Book excerpt: This report describes a computer program to calculate community noise exposure as determined by the Noise Exposure Forecast (NEF) methodology. Studies by the United States Environmental Protection Agency have meanwhile led to the specification of another community noise exposure measure: the Day/Night Average Level (DNL). Since the two types of descriptors are essentially similar, the computer program may be adapted to this new unit when the need arises without the need to redevelop the computational algorithms.

Available in PDF, EPUB and Kindle. Book excerpt: This report is one of a series describing the research program undertaken by the Aerospace Medical Research Laboratory to develop procedures for predicting the community noise exposure resulting from aircraft operations. It reviews current methods for predicting noise exposure around an airport, the results of various social surveys around airports, and psychoacoustic studies of aircraft noise signals, as well as effects of aircraft performance, flight path dispersion, non-standard weather effects, and other factors affecting the accuracy and variability in predicting aircraft noise exposure on the ground. These reviews and analyses are used to recommend a revised procedure for predicting noise around air bases.

This book was released on 1975 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is one of a series describing the research program undertaken by the Aerospace Medical Research Laboratory to develop procedures for predicting community noise exposure resulting from aircraft operations. This report outlines the acoustic measurement test conditions, the acoustic data reduction and interpretation procedures, and the type of aircraft performance information needed to obtain a noise data file for predicting the noise produced by aircraft operations. The procedures result in the descriptions of the noise of an aircraft in terms of the effective perceived noise level, the sound exposure level and several other noise measures. Level flight measurements and static engine noise tests are described, and are applicable to conventional fixed wing aircraft and helicopters.

This book was released on 1977 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is one of a series describing the research program undertaken by the Aerospace Medical Research Laboratory to develop the procedures (NOISEMAP) and data base (NOISEFILE) for predicting community noise exposure resulting from military aircraft operations. It presents the results of field test measurements to define the single event noise produced on the ground by military fixed wing aircraft during controlled level flyovers and ground runups. For flight conditions, data are presented in terms of various acoustic measures over the range 200-25,000 feet minimum slant distance to the aircraft. For ground runups, data are presented as a function of angle and distance to the aircraft. All of the data are normalized to standard acoustic reference conditions of 59 F temperature and 70% relative humidity. This particular volume (Vol. 1) discusses the scope, limitations, and definitions needed to understand and use the subsequent volumes containing the noisefile data for military aircraft.

This book was released on 1976 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report delineates the program operator changes consistent with the additional developments made on the computer program described in AMRL-TR-73-109 (AD-A004 821). The added capabilities and improved diagnostics that form NOISEMAP 3.2 are discussed. NOISEMAP 3.2 is used Air Force-wide to compute community noise exposure from aircraft flying and ground runup operations for preparing/assessing candidate Environmental Impact Statements and planning compatible land use in the vicinity of air installations. Improvements made to NOISEMAP include: (1) Optional outputs in terms of day-night average sound level, noise exposure forecast, and these measures with tone correction and ground runup penalty weightings; (2) Optional contour plotting on a line printer when sophisticated contour plotting software and hardware are not available; (3) Optional capability to perform the noise exposure computations over limited areas rather than the entire airbase vicinity; (4) Computation of the area contained within specified noise exposure contours; (5) Variable grid spacing of the computations to provide sufficient data points in high gradient noise exposure regions; and (6) Plotting of the aircraft altitude profiles to aid in checking the input operational data.

This book was released on 1974 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: A user oriented description of a computer program to calculate community noise exposure due to aircraft operations is given. Formal definition of all allowable card sequences and examples of coding for all types of aircraft operations are presented as well as guidelines for efficient use. The program which is entirely written in FORTRAN 4 produces printed output as well as output compatible with the CALCOMP GPCP contouring package. A discussion of the architecture of the program and the interpretation of the output can be found in companion volumes AMRL-TR-109 and AMRL-TR-73-105, respectively. (Author).

This book was released on 1979 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of field measurements of the far-field noise produced on the ground by military aircraft operating inside Grade-II demountable suppressors during ground runup operations. For these ground runups, data are presented as a function of angle and distance to the aircraft. All of the data are normalized to standard acoustic reference conditions of 59 F temperature and 70% relative humidity. Volume 1 discusses the scope, limitations, and definitions needed to understand and use the volumes containing the noise data. Noise data are presented in this Volume 7 for the following aircraft suppressor systems: A-7 in the AF32A-19 and AF-32A-24 noise suppressors, KC-135A in the modified AF32A-52 noise suppressor, F-4 in the AF32A-14 noise suppressor, F-5 in the AF32A-18 noise suppressor, F-15 in the AF32A-23 nose suppressor, F-16 in the AF32A noise suppressor, F-100 in the AF32A-16 noise suppressor, F-106 in the AF32A-17 noise suppressor, F-111 in the AF32A-13 noise suppressor and T-38 in the AF32A-18 noise suppressor.
