A Levin man is being driven to madness by a mystery noise that wakes him every night.
Gary Madsen said the noise, which he described as a low hum, caused the walls and windows in his home to vibrate and one morning made ripples in his coffee cup.
He's tried everything from sleeping pills to ear plugs, but the mystery noise was so irritating and having such an effect on him that he was considering moving house, or maybe moving town.
"I live close to the train tracks and sleep through that, but this noise - nah," he said.
"It's like a "mmmmm". It's really annoying. It just keeps going and going. It's getting to the stage where I can't handle it anymore."
