Mystery squeak

I work nights, which is why I was sleeping at 12.07pm to be woken by a loud, piercing, brief electronic-sounding squeak. There was another at 12.08, then another at 12.09. I figured my clock radio was finally going round the bend, but when I pressed it to my ear there was no discernible difference in the sound. I turned the volume to zero with no effect and finally disconnected it (it has no batteries) to no effect.

I have checked both my smoke detectors in case they’re trying to alert me to low battery power. No effect. I timed the squeaks; they’re 55 seconds apart. I have poor directional hearing which is a curse in cases like this, but I thought I’d tracked the sound down to my bathroom, so I disconnected the only electrical thing in there: my dishwasher. No effect. Eventually I turned off all power in the apartment, but the squeak is still with me.

There’s a wardrobe next to the bathroom that’s my current best candidate for a source, but there is nothing in there that could reasonably start squeaking every 55 seconds. For a while I thought it was coming from next door’s since the bathroom and wardrobe are next to the shared wall, but I went out into the hallway and listened outside their door and no, as far as I can tell it’s my squeak.

I need ideas now. Brainstorm. Throw things at me. What the hell starts squeaking loudly and keeps squeaking every 55 seconds, on the clock?

Never mind. Guess what? I have a third smoke detector that must have come with the place and that I’ve never known I had. Hey, at least I’m safe from fire.

Nope. Not gonna ask. Nope. Not me. Uh-uh.

I thought for a moment that the ck and the sh keys were swapped on the OP’s keyboard.

:wink:

Ooh, nice one.

I was going to tell you it’s your electric toothbrush - mine evidently makes an “alarm clock” sound when its battery is low, but it’s such a weird noise that you can’t follow it to the source.

I was going to suggest it was this.

My brother did EXACTLY the same thing you did. Drove him and his wife batty for a few days until they finally found a smoke detector in the back of a drawer somewhere.

We had replaced a smoke detector and it was doing the periodic beep. We put a new battery in in, still beeping. We took the battery out - still beeping.
Turns out the beeping was coming from the old one that we replaced, sitting nearby on a desk piled over with papers. :smack:

Whoops. Substitute “washing machine”.

You should have left us with the mystery.
