The hum from hell.

I have a problem. I use a wired USB mouse because none of my wireless mice will work anymore, except the old white Dell mouse that I use for my laptop, and switching it between the two computers is a fucking pain in the arse. As if that weren't bad enough, the wired mouse I use causes the speakers to produce this annoying fucking hum. I can't turn the speakers off, because I play videos on YouTube and games with sounds too much, and constantly turning the speakers on and off would drive me batshit faster than the hum. Can't use the wired Hello Kitty mouse I have, either, or another black wired mouse I have, because both are PS2 mice, there's only one PS2 connector on the back of my desktop machine, and that connector is where I plug my awesome curvy ergonomic keyboard at (yes, it's PS2; I got it cheap at a thrift store). Never had any luck with splitter thingies for PS2 connectors, either.

On the upside, the hum can be hidden by music. So I play music. Unfortunately, I tended to play music anyway before the hum; this is unfortunate because I have a habit of listening to an artist's albums over and over and over again until I get bored or tired of that artist, and move on. It takes a few months to go back to some artists under this system, and if I go back too soon I go batshit. So though I have an extensive music collection, I'm limited in what I can play. And lately I've been playing things that I wasn't ready to go back to yet, all because playing them makes me less crazy than the damned hum does.

Luckily, I was reminded earlier today of something that may save my sanity: certain sounds are like a stimmy to me. I had to stop using this noise-making tube toy I got at OMSI months ago because I'd constantly be making noise with it, to the point where it felt like trying to go cold turkey on an addiction when I put it aside. When Lilla and I lived together, I used to spend hours thrumming the bars on the daybed thing that was my bed, because the sound they made was addictive. And I was reminded today, I feel the same way about bagpipes, harpsichords, and the pipe organ, along with a few other instruments I can't recall offhand. So armed with this knowledge, I can compile a playlist of songs that are addictive to the point where I can play them over and over and over again and never get tired of them. Hell, it may come to a point where I have to put that playlist in my liePod to keep from going insane from cold-turkeying it when going out of the house.

Oh, that hum? It isn't even steady. It has a kind of pattern to it. It varies in pitch and volume in a pattern. I just don't know why it happens. But it's like an anti-stimmy. I can tolerate it for a few minutes, and then it's like "MUST STOP THE HUM OR GO FRAKKING BATSHIT INSANE!!!"

Heh, this is the kind of thing I think I should cross-post to asperger. I think I will.

Wrap aluminum foil around the whole length of the speaker wires (or as much as you can); connect it to "ground" if possible. Ask kengr to help if you don't know what I'm talking about.

It's a laptop. Internal speakers. My guess is that the shielding (or lack thereof) on the USB mouse is picking up 60-cycle. I've suggested looping it thru a ferrite donut. If we can find one. Radio Schlock doesn't seem to have those anymore, just some snap together ferrite "chokes" that may not have a big enough hole to run the looped cable thru...

No, it isn't. The problem is with my desktop PC, you silly thing.

the reason i didn't suggest shielding the mouse wire is because moving the mouse around will soon break the aluminum foil. perhaps the kind of cylindrical choke they put on monitor cables (and sometimes even power supplies) would work, but i think those are tuned for RF, not for 60 Hz. maybe even just re-routing the speaker wires would help - try to get them at 90° to the mouse wire if possible. get a piece of perforated aluminum (the kind of stuff they use for radiator enclosures) at Home Depot, attach a ground wire with an alligator clip and ground it to whatever's convenient, and position it between the mouse and the speaker cables. i'm sure you can think of lots of other possible ways to shield one from the other.

It might be simplest to get a new mouse. The Best Buy website has a few wired and wireless ones for about $10 with free shipping.
