I'm trying to figure out what is causing the sounds that I'm hearing from planes passing over my house. I'm located approximately 60 miles NW of ATL. The noise I hear sounds like a turbine rapidly spinning up, and then back down approximately 5 seconds after. My theory is that this is from an initial descent, relieving some resistance on the turbine blades, but can't quite find the sound anywhere else. I have never heard this sound prior to moving here to GA a year ago and I have lived near major airports near Newark, Virginia Beach, and several military bases throughout my career. I do not have a recording yet as the planes are not quite visible when this occurs and I also don't hear the approach.
