"The noise walls, between Stephensons Road and Stanley Avenue, have been the subject of residents' complaints since they were installed last year - many complaining that traffic noise had increased since the wall's construction.

The outcry prompted VicRoads to test noise levels near the freeway.

Last week, VicRoads told the Journal that several locations such as the one in Therese Avenue surpassed threshold noise levels of 68 decibels.

Group convener Peter Smith said the results validated what residents had been saying "for years".

A recent survey of 330 households by the group revealed 72per cent of households believed noise had increased since the noise walls' construction. Many also feared that noise levels would increase after extra lanes on the Monash Freeway were opened next year and speed limits returned to 100kmh.

"I think VicRoads has got to have a look at the whole design of these walls," Mr Smith said. "Our argument was essentially that we don't care what the readings are, the transport minister said it would be quieter and it's clearly not."

He called for VicRoads to upgrade its 30-year-old noise wall standards to match EastLink's 63dB(A) threshold.

A spokeswoman for VicRoads said the areas which exceeded noise levels would be "prioritised for additional noise attenuation treatment under the retrofitting program". She said noise levels were continuously monitored in response to community concerns.

VicRoads' traffic noise reduction policy had been in place since the 1970s with "minor amendments" adopted since its introduction and there were no plans to review it , she added.

A State Government spokesman did not respond before deadline.
