"It was good to join the team and go out and see for myself the hotspots where the predominant number of these concerns are from and to hear the noise myself," Mrs Chadwick said.
"I found it very inconsistent, but it is obviously a growing concern for the community. It is a complex issue and there is not one simple fix."
Mrs Chadwick said she did not hear the "crashes and clatters" reported by residents in the area, but was looking forward to meeting with members of the Eastside Residents Action Group to discuss the problems.
"I didn't stay there all night but now I have a much better understanding of the issues, it doesn't throw up an easy answer."
She said she visited areas on both sides of the mill and places up the hill in Lynmore.
"There was a consistent low level noise but I did not hear lots of bangs and crashes. I really thought I would have heard those," she said.
Mrs Chadwick said the council had almost completed compliance testing and staff had "the noise levels pretty clear and I expect a full report by Friday".
The council is now undertaking a review of its processes around the complaints.
