Title:House Noise-Reduction Measurements for Use in Studies of Aircraft Flyover Noise
Issuing Committee:A-21 Aircraft Noise Measure Noise Aviation Emission Modeling
Scope: This AIR describes the results of some house noise reduction measurements that were made in five locations in the U.S. in 1966, 1964, 1967, and 1969. The houses used in these tests included a wide range of construction types of single and multiple family dwellings. The house noise reductions also cover a wide range. The average house noise reduction developed in this AIR should be used only when such an average is needed. The principle objective of this AIR is to use these noise reduction measurements to develop curves showing the noise reduction of aircraft flyover noise when the noise passes from the outside to the inside of houses located in various climates. The noise-reduction data presented herein can be applied to measurements of aircraft noise made outdoors in order to estimate the noise levels indoors.【英文标准名称】:Eurocode3:Designofsteelstructures-Part1-5:Platedstructuralelements;GermanversionEN1993-1-5:2006+AC:2009
