A resident has made a tape recording of a mystery humming noise that has been driving people mad as far apart as Halifax and Queensbury.
The recording was made around midnight in Queensbury where residents have complained about being kept awake by an incessant humming noise.
Listeners are urged to wear a pair of good quality headphones which will allow them to properly hear the humming noise, which was recorded this week.
Many residents in Halifax have complained about the noise to Calderdale Council, either by email or by filling in an online form to report it as ‘noise pollution’.
Residents in Queensbury, near Bradford, which is about four miles from the centre of Halifax, have also complained to Calderdale but have been told to raise it with their own local authority.
Some householders have had to take sleeping tablets and have been unable to properly focus while at work.
One Halifax woman said: “I thought I was imagining it until I saw others mention it on Facebook.
“I’d say the last three or four months have been the worst – a constant low hum at night.
“I work full-time and have had to now rely on sleeping tablets to help me sleep for the past month and probably until it stops.
“It’s affecting my performance at work and my mental health. I really hope it gets sorted.”
Last week Calderdale Council confirmed that officers were investigating the source of the noise.
Councillor Scott Patient, Calderdale Council’s Cabinet Member for Climate Change and Resilience, said: “Complaints about noise are assessed by the Council and where appropriate we will take action to try to resolve the issue.
“Our Environment Health team is currently investigating complaints from residents of North Halifax about noise in the Holmfield area.
“Officers are in contact with the complainants and with a business in the area to understand the problem and assess options.”
YorkshireLive has approached Bradford Council for comment.
