Guys
Please don't lose sight of the blindingly obvious here.
Just 'cos ATC tell you something at 1000' doesn't mean (and never has meant) that you have to action it at 1000'.
Deal with it however you like, even scribble it down and read and do it later, but the noise abate is there for a reason. Do the other stuff when it needs to be done.

Ask you Chief Instructor what you should do if the instruction were prefixed "..after noise procedure, climb FL140........."
