Metgasco noise is just ho hum
A SYDNEY University professor reviewed Metgasco's study of the noise made by test drilling at the Glenugie site and said the results would not be loud enough to keep people awake at night.
Geoscientist Dr Iain Mason reviewed the Metgasco study.
"The consultant who undertook the measurements is competent, his grasp of prevailing standards is sound, his interpretation was reached objectively, as was his recommendation," Dr Mason said.
The study found the Glenugie site complied with noise regulations and recommended no change to the operation.
"Noise levels are only a part of the story.
"Noises one dislikes can be incredibly distressing.
"A mosquito puts out very little energy. Yet the human ear tunes in so hard that sleep may become impossible without a white noise source in which to drown it."
The consultant scientist from Pollution Control Consultancy and Design who did the study said all equipment on site was running during the data collection period.
No reading (taken at distances from 520-1940m from the site) exceeded 40 decibels, equivalent to the hum of a fridge.
Glenugie resident George Oxenbridge claimed the drilling was like a jet plane taking off.
Mr Oxenbridge lives about 1km away and said in an interview with the ABC on January 11 noise from the drilling was so loud it disturbed his sleep.
"I was awoken at 10 o'clock last night to the roar of like a jet plane taking off," he said.
Metgasco confirmed there had been one-off work on January 10 which was louder than usual.
The study started taking readings the day after that louder work.
