Well here is a noise story. For ten years I lived at an airport, attached 800 sq.ft., condo to a 5,000 sqft hangar. This is an airport with airport people. My neighbor would always raise holly hell, when I did a compressor wash or any maintenance runs outside the hangar. Neighbor would come over and tell me to take it out to taxiway (not practical). It was a Turbine helicopter (the quietest one made). Haters are going to hate. Show up with a jet self launch and soon you will find out if your neighbors will accept, my guess is they will not. Turbofan are much quieter. This is why (among other reasons) early Lear Jets are not permitted at many airports (jet engine = noise)turbofan, much less noise.

*haters gonna hate* in the parlance of our times.
