Modelling shows areas such as Luddenham,Eastern Creek,Glendenning and Werrington are among those that will experience up to 49 flights a day by 2033 where the sound will exceed 60 decibels – the equivalent of a conversation.
Greendale,a largely rural area south of the airport,will be one of the areas worst affected,with up to 199 flights a day each above 60 decibels by 2033,and up to 99 planes passing overhead at 70 decibels,which is equivalent to the sound of a washing machine. Homes near Erskine Park,north of the airport,will also be subject to aircraft noise over 70 decibels.
The areas that suffer high noise levels will also expand by 2040 as the number of flights to and from the curfew-free Western Sydney Airport grows.
Wollondilly’s independent mayor Matt Gould said residents in places such asSilverdale,close to Warragamba Dam at the foot of the Blue Mountains,would be heavily impacted by aircraft noise. That’s due partly to plans for planes to mostly land from the south-west and take off towards the south-west if wind conditions were calm late at night.
“We will be pushing for there to be some noise remediation. If it was good enough for Mascot when they built the third runway,it should be good enough for our residents,” he said. “Silverdale is a very quiet place,so the sensitivity to these noise levels are higher.”
The government releasedan online tool on Tuesday that allows residents to plug in their addresses to see how their homes will be disrupted by noise from aircraft flying to and from the $5.3 billion airport.
