Thanks for finding that article. I never would have looked for it. Our club is in the process of negotiating a new flying site. There are two neighbors that have expressed some concern about possible noise from the site. One is approximately 120 yards from the closest boundaryand 370 yards from the runway, the other is approximately 170 yards from the closest boundary, and 420 yards from the runway. I think we will propose performing just such a survey after opening the field. Our local jusrisdiction has a 65 db limit at the property boundary, so we can use the survey to either document compliance, or modify our operations.
