Hoping for some advice before I go mad. We have been hearing noises in our house for over a year which sound like a TV on too loud and a vibrating through the bed.
We have turned off all electric in our house, the gas and mains and it persisted and we went and stopped at another house to make sure it wasn't us. Upon further investigation it seemed that there was a wall mounted TV causing the issue and when this was turned off the sound was better.
However we could still hear something and feel the vibration. I asked the neighbour and they said everything was off and offered to help.
They do have a TV with speakers and a sound bar and do stop up late as they both work shifts, but we have been assured that this was off when we said we could feel it.
We obviously don't want to be accusing the neighbours if it is not them, is there any way to prove where this sound and vibration is coming from. They do tend to leave the tv's on all night, and advised the heating is on too. We don't want to accuse anyone as they have been working with us but it's really affecting our mental health.
How do we get toe the bottom of this?
