The good news is that Adelaide airport has a fairly restrictive curfew. These poor homeowners don’t have to put up with air traffic 24/7
Now I'm in Launceston a bit further from the airport, the 2am Toll Freight flight is definitely something I notice.
Have you considered Davenport? :D No flights but endless shipping going on.
Less serious questions: Is it a 140dB alarm? Do you recognize models by sound? I assume the A320 is medium-size, do they have bigger airplanes?
Not 140dB, but to give you an idea of how loud it was, we had to pause the TV or conversation when planes were coming over because we couldn't hear it.
We could absolutely recognize models by sound.
Very rarely did we have anything larger than an A320, Adelaide is not a big airport, but we did have some big military aircraft come through.
