At first glance, Holmfield looks like a quiet village. But for some residents, their lives are being made a misery by a mysterious rumbling noise in their homes. Not everyone can hear it and investigations have failed to find the source. The BBC went to investigate what locals call the Holmfield Hum.
"I love my home but some days I absolutely detest being in it. It feels like there's no happy space here any more."
Yvonne Conner hears the hum. Aside from the odd weekend when she has had to "escape", it has been the background sound in her Victorian stone terrace since 2019.
For her, the hum is a constant droning sound, like the whirring of a washing machine or an idling diesel engine. Not everyone in Holmfield experiences it, but for those that do, its impact has been severe, even costing Yvonne her health and job.
As we chat in the high-ceiling kitchen at the back of the house, Yvonne says the hum is whirring away, like it does most days and nights. I concentrate on trying to pick it up, but can't hear anything.
She explains: "As much as I can hear it I can feel it on my eardrums. It resonates and feels like a pressure against them. That's pretty much what it's like all the time."
Therefore, he says, it's not an exaggeration for these sufferers to say that their lives are being ruined by the hum. Since 2000, the World Health Organisation has recognised low-frequency noise as an environmental problem that causes various health impacts.
In Yvonne's case, she says living with it has caused shingles, anxiety and headaches. At its worst, she quit her job as a charity support worker because the stress left her unable to function properly.
The maddening reality she endures means at times she has questioned her own sanity, wondering whether the rumbling really exists.
It's not an uncommon response, says Peter. Having been involved in similar cases over his 30-years experience, he finds people like Yvonne are hearing real noises.
He explains: "Quite often they start doubting themselves and think they're going crazy. We're able to go in and prove with science that by measuring it, it's there and they're sane.
"The problem is then trying to find where it's coming from and it's a bit like searching for that elusive needle in a haystack.
"If you imagine the soundscape people are living in, there's all sorts of noises coming and going day and night so you've to effectively turn everything off to start the job of finding it."
Peter says common causes of such sounds can be something as minor as a mains hum in the home, a neighbour's hot tub, a transformer on a telegraph pole or industrial premises. Often it may be that residents are hearing different versions of the hum or the noise is coming from a mixture of sources.
"When you go in with the right equipment and approach you can get a sonic fingerprint which will then start giving you some clues as to what it could be.
"For example, if there's a 50Hz element to it, it's probably mains related so you would start looking at things likes transformers near the house."
Back in Holmfield, the council said it had "given its all to the investigation and left no stone unturned" but has now closed the case.
