The man is said to be a “severe disruptive vocaliser” — someone who regularly makes loud, unintelligible noises.

One neighbour said at least half a dozen households near the property found the noise “distressing”.

“We’ve had neighbours who sleep in the loungeroom because they can’t sleep in their bedroom,” Carol (not her real name) said.

Severe disruptive vocalising is said to be common in long-term care, affecting as many as 10 to 30 per cent of nursing home residents.

The house was purpose-built by the Department of Human Services and is run by the EW Tipping Foundation.

Carol did not want to identify herself to prevent identification of the disabled man and his mother.

Benambra MP Bill Tilley said it was a “very complex” issue that he was working hard to try to resolve.

“When it comes to the residents being able to have peaceful enjoyment of their properties, I absolutely support them in this,” Mr Tilley said.

“And I support the work that Tipping is doing and other services in that area.”

Mr Tilley said he only just received a letter from Community Services Minister Mary Wooldridge over the issue, which said it was still being assessed “and work being done to remediate all the challenges so that everybody can have peaceful enjoyment of where they live”.

Carol said she had been in regular contact with the department and the foundation since last November.

The house — built under the “My Future My Choice” program for younger people under 50 — was retro-fitted with double glazing in March.

“I was starting to relax a little bit, and then a few nights ago a window was left open so I was subjected to it yet again.”

Carol said residents had backed the concept of the house from the moment they received a letter flagging its construction.

In an email to Carol, the foundation said the resident did not give any indication when he moved in that there could be such problems. “When the tenants moved (in) none of them presented as individuals that would cause any concerns to the neighbours, none of them presented as challenging or disruptive and they were all seen to be suitable for the model,” it said.
