CONSTANT noise from the Sapphire to Woolgoolga Pacific Hwy upgrade has residents at their wits' end and demanding action from the State Government.
The United Residents Group of Emerald is calling on Coffs Harbour MP Andrew Fraser to petition the NSW Parliament for an open dialogue with Roads and Maritime Services on implementing adequate solutions.
During a peaceful protest on Tuesday, residents said ongoing delays to the release of a highway noise report commissioned by RMS last year were "unacceptable".
Woolgoolga resident Steve Moody lives 500 metres from the highway, and said noise levels are already above accepted standards outlined by the Environmental Protection Authority.
Steve has conducted his own readings on a validated noise monitor which he said are higher than approved levels of 55db during daytime hours, and 60db at night.
He claims to have registered night-time readings of 60 to 70db, strengthening his call for the RMS to extend highway sound barriers and install noise-breaking cameras.
"We are sleeping with ear plugs at night and that's with the windows closed," he said.
"The are many mitigation measures that can be taken to limit the effects of heavy vehicle compression breaking but so far there has been a total unacceptable response to the level of harm and community angst being caused."
The World Health Organisation says sound noise levels more than 55 decibels are considered "increasingly dangerous for public health" and can impact on hormone level changes, mental illness and cardiovascular illness.
RMS states the post-construction noise report will be released later this month.
