"The civil aviation industry is already introducing small, incremental decreases in aircraft noise", she says. "But we are aiming for a radical change in noise levels - so that beyond the perimeter of the airport, the noise of aircraft flying would be imperceptible to the public."

..make the perimeter fence further from the runway?

Main cause of noise is engine-related though isn't it?

I belive nowadays with the very latest engines the airframe actually generates more noise than the engines during the approach ie engines close to idle but lots of things hanging in the airflow.
