Determination of Noise Exposure around an Airport IGARASHI, Juichi NISHINOMIYA, Gen This paper presents a study of drawing the noise exposure contour around an airport. The contour was figured out from the measured data obtained in the vicinity of Osaka Airport. It is compared with the calculated contour based on the data of FAA, the specified flight paths and the scheduled operations similar to those of the period of measurements. The methods of determination of PNdB, duration and tone corrections are also mentioned together with the relation between PNdB and dB(D) or dB(A). 資料番号: SA2400849000 東京大学宇宙航空研究所 Institute of Space and Aeronautical Science,University of Tokyo 1972-03 eng departmental bulletin paper https://jaxa.repo.nii.ac.jp/records/34455 0372-1418 AA00675986 ISAS report/Institute of Space and Aeronautical Science,University of Tokyo 37 2 53 69 https://jaxa.repo.nii.ac.jp/record/34455/files/SA2400849.pdf application/pdf 955.1 kB 2020-01-24
