Alpine Airport - Phillips Petroleum, North Slope Alaska - performed detailed noise analysis for the Alpine Airport as part of a study of the affects of aircraft on birds and nesting habits. Constructed INM noise model using base maps provided by Phillips Petroleum and ABR, Inc. for 5000 foot airport in the north slope of Alaska . Performed on-site noise monitoring and noise model calibration over a 1-week period to include 20 monitoring locations surrounding the airport and performed flight track monitoring to include as input into the FAA IMN. The noise monitoring was performed in 1-second time intervals, and the data downloaded into a computer for post analysis. The data post analysis provided a second-by-second time records for each aircraft event, and included L max , L eq , and SEL. The data was tabulated by aircraft type for use in the final report. The technical report included methods of analysis, noise modeling and monitoring results, and other general information, such as helicopter flight and noise level information. Worked with ABR Alaska to plot noise contours over CAD files with nesting sites. Published technical documentation on analysis.

Medford Regional Airport, Medford, Oregon - Performed analysis for runway extension. The purpose of the study is to evaluate the potential for aircraft noise impacts due to extending the airport’s primary runway from 6,700 to 8,800 feet, an increase of 2,100 feet. The extension would occur at the north end of the main runway. Airport noise level projections were performed using the FAA Integrated Noise Model (INM) Version 5.2. All airport noise levels in this report are assessed in terms of the yearly day-night average sound level (YDNL) contours.

Seattle-Tacoma International Airport, Seattle, Washington - Assisted with the design of complete noise monitoring and flight tracking system. Recommended products and assisted in system specifications.

Seattle-Tacoma International Airport, Seattle, Washington - Designed a system for the measurement of noise transmission for homes located near the flight paths of aircraft at Seattle-Tacoma Airport. System included hardware and custom-written software with measurement and analysis of noise due to aircraft overflights.

Portland International Airport, Portland, Oregon - Assisted with the design of complete noise monitoring and flight tracking system. Recommended products and assisted in system specifications.
