An estimate of the global impact of commercial aviation noise
This study estimates the impacts of commercial aviation noise at 181 airports around the world. These airports are located in 38 countries plus Taiwan, with 95 of the airports located in the United States. They are part of the 190 Shell 1 airports in the FAA's Model for Assessing Global Exposure to …

Comparison of methods for evaluating impacts of aviation noise on communities
Community opposition to the noise concentration from precise NextGen Performance-Based Navigation (PBN) aircraft arrival and departure procedures poses a significant threat to the future of these procedures in the U.S. National Airspace System. A substantial number of complaints concerning airport …

Development of an income-based hedonic monetization model for the assessment of aviation-related noise impacts
Aviation is an industry that has seen tremendous growth in the last several decades. With demand for aviation projected to rise at an annual rate of 5% over the next 20 to 25 years, it is important to consider technological, operational, and policy changes that can help accommodate the forecasted …

Impacts of airports on the quality of life of surrounding communities
… such as, for example, job creation and noise. The population living in the airport's proximity notices, cares about, and perceives its impacts which have often been studied only partially in literature. This thesis used the concept of Quality of Life to look at impacts …

Three-Bladed Propeller Design for the Reduction of General Aviation Radiated Noise Characteristics
… to design a quiet 3-Bladed propeller for general aviation aircraft. A combination of design technique and analytical predictions using the NASA Aircraft Noise Prediction Program - Propeller Analysis System (ANOPP-PAS) was used to achieve this goal. The propellers were designed for an engine power …
