Just a quick question-
We’re on Crystal Palace Road, backing onto Darrell Road, about midway between The Great Exhibition and The Actress, and both my daughters (late teens/early twenties) are complaining about an intermittent, very high frequency noise that they find very uncomfortable. It’s worse for the older one as she’s trying to study for the finals of her degree coming up in May, and she’s already having hospital treatment for an ear condition. The sound can even be heard from indoors with the windows closed.
Neither my wife or I can hear it but it’s been going on for a few days now and I wonder if it’s one of those ultrasonic cat/dog/fox repellents, maybe connected to a movement sensor, that only registers with animals and younger people with much more sensitive hearing?
If that is the case would you mind turning it off please as it’s causing a very real problem.
Many thanks.
