550/9-82-326

PB82-162066

[This report examines the judicial trends in airport noise litigation by analyzing the decisions from many of the relevant legal cases. The significant issues arising out of these various cases examine this conflict from four viewpoints: (1) who is liable for aircraft noise related damages? (2) what is the scope of airport use restrictions? (3) what are the legal theories and trends in awarding aircraft noise-related damages? (4) what is the effect of land use planning and environmental impact statements on airport control? This extensive case law review indicates that the courts are continuing to hold the airport proprietor liable for aircraft noise-related damages. The judiciary is also expanding the legal theories and granting recovery for noise-related effects on people under the nuisance theory of emotional distress as well as under the traditional inverse condemnation theory for deprivation of property.]

Procedures to Estimate Airport Residential Relocation Costs
550/9-82-327
PB82-239641

[The Uniform Relocation Assistance and Real Property Acquisition Policies Act of 1970 is reviewed. Procedures are provided for: (1) developing a well-defined set of cases for which relocation costs may be estimated; (2) determining the costs in current dollars for each expense item in each relocation case; and (3) determining the frequency of occurrence for each case as applied to specific airports.

[This report presents results of an estimate of the national exposure to aircarrier aircraft noise through the year 2000. The forecast was carried out to show the effect of two types of noise abatement options. The first consisted of modifications to FAR Part 36 proposed to the Federal Aviation Administration (Notice 76-22) by the U.S. Environmental Protection Agency which would establish lower noise limits for newly designed aircraft in the years 1980 and 1985. The second type consisted of alternative power cutback procedures (FAA AC 91-39 and two variations of ALPA/Northwest Airlines procedure) coupled with minor variations on approach procedures.]

Noise Effects of Concorde Operations at JFK International Airport (November 1977 through November 1978)
550/9-79-316

[The FAA measured the noise at several communities in the vicinity of JFK International Airport due to the operations of Concorde and subsonic aircraft. This report presents the results of an analysis by the EPA of the FAA noise data which leads to interpretations of the effects of Concorde operations on the public that are different in significant respect from what might be assumed from a cursory reading of the FAA reports.]

Urban Noise Survey
550/9-77-100
PB82-148982

[The results of a social survey of over 2,000 respondents at 24 selected urban locations throughout the United States. A social survey (coupled with an extensive noise measurement program to acoustically describe the urban environment) was conducted to sample opinion over the entire range of noise exposure and population density characteristic of non rural America. The objectives of the National Urban Noise Survey were to establish relationships between noise exposure and human response as a function of situational and attitudinal variables associated with the life styles of people residing in urban areas away from highways and airports, as well as to establish the outdoor noise levels at which noise becomes the salient factor in the generation of annoyance as a response indicator.]

Notice of Proposed Rulemaking on Two-segment ILS Noise Abatement Approach for Turbojet Engine-powered Airplanes (EPA/DOT)
550/9-75
DOT

[In accordance with a recommendation by the Administrator of the Environmental Protection Agency, the Federal Aviation Administration is considering an amendment to Section 91.87 of the Federal Aviation Regulations which would provide noise relief to communities in the vicinity of airports by prescribing a two-segment Instrument Landing System (ILS) approach for civil turbojet engine-powered airplanes.]

Notice of Proposed Rulemaking on Reduced Flap Setting Noise Abatement Approach for Turbojet Engine-powered Airplanes (EPA/DOT)
550/9-75
DOT

[In accordance with a recommendation by the Administrator of the Environmental Protection Agency, the Federal Aviation Administration is considering an amendment to Section 91.85 of the Federal Aviation regulations which would provide noise relief to communities in the vicinity of airports by prescribing reduced flap setting procedures for civil turbojet powered airplanes.]

Aircraft Noise Certification Rule for Supersonic Civil Aircraft
550/9-75
*

[This report presents the supporting data for a proposed noise certification rule for supersonic civil aircraft. The background information presented shows that supersonic transports are inherently noisier than subsonic jet transports. It is concluded that current designs of SST aircraft cannot comply with FAR 36 but that future designs can at least meet those requirements. In view of these conclusions as well as the other factors discussed, five of the various regulatory options are recommended for further consideration for the development of one or more rules.]

Noise Measurements of Concorde 02 Approach and Takeoff at Dallas-Ft. Worth and Dulles International Airports
550/9-74-013
PB-245156

[The numerous data points measured at Dallas-Ft. Worth and Dulles International Airports and plotted as a function of level versus distance show a scatter sometimes exceeding +5EPNdB. Direct comparisons of Concorde and 707 approach noise were possible at Dulles. These few measurements indicate the Concorde noise levels relative to the 707 levels to be less, in general, at 2.6 n.mi. and greater at 3.6 n.mi. from threshold. It would appear that when measured data are compared with the theoretical curves there is no reason to believe that the noise levels measured under FAR 36 or Annex 16 conditions claimed by the Concorde developers will not be achievable.]

Civil Subsonic Turbojeet Engine-Powered Airplanes (Retrofit and Fleet Noise Level
550/9-74
FAA

[The FAA has been concerned with the noise levels of turbojet (axial flow jet and axiam flow fan) powered airplanes that do not comply with FAR 36 since its promulgation in 1969. Two ANPRMs and one NPRM related to retrofitting operational airplanes to meet the noise levels specified in FAR 36 have been published for public comment. This report examines these three proposed actions in detail and recommends two regulations based upon their best features. The first regulation would be a straight retrofit rule. The second regulation would be a Fleet Noise Level (FNL) rule. The Analysis Section discusses technology options for source noise control including Quiet Nacelles, Refan, and miscellaneous other methods applicable now and in the future to all civil subsonic turbojet engine-powered airplanes. Included in the analysis are estimates of the noise levels and the unit and investment costs for the various retrofit options available to the large transport airplanes and to the smaller business jet airplanes as well. Also included in the Analysis, are discussions of the concepts of Fleet Noise Level (FNL), Day-Night Level (Ldn), and Noise Exposure Forecast (NEF) with numerical examples, which illustrate the pertinent relationships.]

AD-767205

[In support of the main document, "A Basis of Limiting Noise Exposure for Hearing Conservation", EPA Report 550/9--73-001A, this report compares the relationship of noise exposure of Noise Induced Permanent Threshold Shift (NIPTS) as predicted by the currently available works of Passchier-Vermeer, Robinson, Baughn and Kryter, and the yet unpublished work of the National Institute of Occupational Safety and Health. The works of Passchier-Vermeer, Robinson, and Baughn are selected since these are the only works that completely predict the relationship between NIPTS and noise exposure for various audiometric frequencies, sound pressure levels and population percentiles.]

Public Health and Welfare Criteria for Noise
550/9-73-002
PB-241000

[The Noise Control Act of 1972 requires that the Administrator of the Environmental Protection Agency (EPA) develop and publish criteria with respect to noise. These criteria were to "reflect the scientific knowledge most useful in indicating the kind and extent of all identifiable effects of noise on the public health and welfare which may be expected from differing quantities and qualities of noise. This criteria document, therefore, served as a basis for the establishment of the recommended environmental noise level goals to be related to the "Levels Document" called for the Section 5(a)(2) of the Noise Control Act (refer to EPA Report 550/9-74-004).]
