Residents of a village in Halifax have urged officials not to give up investigating the source of a mysterious humming that has plagued them for a year.
The low-level noise has left villages in Holmfield unable to sleep and has damaged their health, according to the BBC.
Calderdale Council and Bradford Metropolitan Council have been attempting to get to the source of the humming, which some residents believe is coming from local industrial units.
But locals fear that the local authorities are now getting ready to stand down their investigation and a petition urging them to continue has so far gathered 400 signatures.
One resident, Yvonne Conner, told the BBC that the sound was being detrimental to her health, adding that some neighbours were booking weekends away to escape it.
She explained: ”It's causing issues for people such as lack of sleep, headaches and pressure to the front of the head, foggy brain, painful ears, stress and anxiety which has led to me having a case of shingles.
"Residents have been unable to relax in their own home for nearly a year. The noise is continuous day and night.”
Calderdale Council councillor Scott Patient told a recent local council meeting that the investigations are ongoing.
He said that “tenable inquiries” were still being made and that “as long as this exists [they] will continue to investigate”.
