A mystery noise is driving several Warrnambool residents to despair one even selling her house to escape the incessant drone.
Two residents in Mitchell Street and two others, less than a kilometre away in Alice Place, have aired their annoyance over what they describe as a low, turbine-like noise in their north-east neighbourhood.
"I just can't sleep and even when I put in ear plugs I can hear it," one woman said.
"I've got chronic fatigue syndrome and just can't rest, yet I still have to go to work.
"I've sold my house and am moving to another area."
Three other residents also said they too found it hard to sleep, especially on calm nights when the sound was more noticeable. "It's not excessive, just irritating and sometimes it keeps me awake night after night," one retired woman said.
"A pumping station has gone in near the Aberline Road roundabout. Maybe that's it."
A mother and daughter in Alice Place described the noise as intermittent.
"It drives me insane sometimes," the mother said.
"I put in ear plugs and pull the bed covers up high, but it still bugs me. It's very strange. At first I thought it must have been the smart meter."
Her daughter described the sound as "kind of like a really low turning noise". "It wakes me up in the mornings."
Checks by The Standard indicate the noise could be coming from nearby water system installations.
