When DP took the DC out earlier I heard a pinging noise, it sounded just like notifications on a phone, possibly from the front room.
Which freaked me out a little as my phone was next to me, DP and DS had theirs on them. No other phones in the house.
I got up and checked anyway and the sound stopped.
I've heard it again, several times, all day. I'm not sure it is a notifications noise or not now, although it is very like it. I think it might be a muffled noise that's the same pitch. There's no rhythm to it, it's random just like notifications.
I've heard it about 20 times while writing this.
Can anyone help work out what it is?
I've only heard it when I'm in the dining room. I'm on the computer but it sounds like it's coming from behind me.
I've can only heard it in here.
I still heard it when I turned the computer volume off.
No other devices in here, although there is a piano in here. Could a piano make a muffled noise that sounds like a bing?! How would that happen?
I'm mystified!
