Combating Harassing Use of Mosquito Noise Device?
amicold asks: "For a while now my neighborhood has had to deal with an elderly neighbor who has displayed a slightly paranoid attitude towards myself and the fellow younger-adults of the neighborhood, believing us to be attempting to harass him in our day-to-day activities. Recently, he installed a Mosquito ultrasonic noise device as an apparent attempt to 'get back at us' for our harassment. As the Mosquito emits a sound that's well out of his hearing range, he can't hear it, while most of the rest of the neighborhood is under 40 and can; at which point it's causing everyone a great deal of discomfort. Unfortunately, because the police also can't hear it, we can't get the authorities to do anything about it, leaving us empty-handed in our attempts at getting some peace and quiet back. What can we do to either help the police realize how disturbing this device is, or counteract it so that it's no longer disturbing us? And is this the first of what may be a growing trend of civilians using high-tech discomfort weapons as a method of neighborhood warfare?"

Take pictures of it. Print out the link you have in your post and any other documentation you can find on the thing. Ask a community service officer from the police to come out. She will probably be a she. She will probably be young, and since not carrying a gun, will not have spent a bunch of time on the firing range ruining her hearing. She will hear it, and since the docs clearly show it is designed to be annoying, she will be on your side. Probably. Maybe. You can try it and hope, anyway.
Plan B. You like Hendrix, right? With breakfast. Early. Turn it up to eleven.
Some mornings it's hardly worth chewing through the restraints to get out of bed.
Build a similar device to emit noise at a slightly different frequency. The result will be horrible sounds as the two waves interfere. The horrible sounds will seem to come from both your source and the original source. You may get the blame but at least the cops/etc will believe that an issue exists.

Am I the only one that thinks this is a novel Slashvertizement?
How many of you thought "hmmmm. I could use this to really annoy xxx"?
And note that the link goes to a specifc supplier of such items. Not a generic link.... say a wiki. I mean, who really believes that some guy cannot get a cop under 40. Cannot figure out that he should talk to the police and explain more, or maybe go to see a lawyer... or maybe sneak into his neighbor's year with a baseball bat and a ski mask?

Betcha if you inject in some epoxy or expanding foam into said cone in quantities that won't be visible from the outside, the horn tweeter will stop making said annoying tone or at least attenuate the sound output or alter the frequency so that it won't be as bad.
Do it right and it'll probably still look like it was still working this way too. Much faster than trying to disassemble something and disable it while making it look like it's still working. The old fart can't hear it anyways, so he'd never know that you'd broken the horn tweeter as many others have pointed out.
You can also just go for a brute force/economic war approach:
Your cost: A couple of bucks for a tube of quick setting epoxy with syringe type applicator. Or, if you don't want to do this manually or the unit isn't readily accessible try some home made/customized paint balls filled with acid/epoxy/superglue/something nasty His cost: $600-$750 + shipping per unit disabled.
Just how many times do you think this guy will be able to afford to replace this device repeatedly? He's probably on fixed income so it's either the Mosquito or the Heart Medications/Doctor's Visits/Food/Heat/etc. The problem will soon go away given enough cheap paintballs I suspect.
War after all is really a matter of economics. Does the damage you cause cost more to your opponent than it does to you and which of you can continue spending money while racking up damage/cost the longest? The guys with the biggest budget or the ability to do massive damage to the other side for cheaper usually wins.

There are no stupid questions...just stupid people.
That sound is only 15 KHz, and the mp3 has 48Khz sampling rate. And the buzzer in the mobile is perfectly able to reproduce high frequencies, it's the low freqs that cannot be reproduced.
You could escalate the conflict by using high tech countermeasures which will piss him off and turn his relatives and friends against you, or make peace and have a nice quiet neighborhood. Hmmm, which way to go, never ending warfare on the one hand, or peace and quiet on the other?
If you go with high tech warefare then you will stimulate the economy by propping up the companies selling sonic noise cancelling systems. And he will of course provide even more stimulation to the economy when he installs an infra-red insect repellent that fries your border plants. And then you have to invest in a cryogenic thermal redirection unit to protect your flowers, after which he will escalate with a plastic dissolving mist spray device, all great news for the high tech neighborhood armament corporations, aka, the militarized neighborhood complex.
This will be fraught with unforseen complications and collateral damage. Your paper boy will refuse delivery, the water meter reader will not dare enter the property, causing an unpaid bill, and various charges about maliciously killing pets will pop up. You can stay the course until he gives up, but just make sure you understand that you may be liable for accidents caused by radio frequency interference with passing vehicle's electronics.
Or you could just walk up to the guy and say "Hi neighbor, is there a problem, and if so, lets work it out."
Naahh, not a chance. Get out the mini trebouchet and carpet bomb the hell out of him with marbles, eggs, and anything else you have handy! Screw the bastard more than he ever thought of screwing you! Worry about the consequences later, after all you don't have to pay for it, or at least not most of it.
No no, you don't want to do anything he can press charges about, and you shouldn't do anything that isn't a direct step in solving the problem.
Find the noise device, find its speaker, and stick a hat pin in through the speaker grille to pierce the speaker. Then remove the hat pin and walk away. The hole will cause the speaker to tear itself and will cease making any meaningful volume of noise, and the old coot won't be able to hear the difference. More importantly, he can't really do anything with the police about it because to explain how it's broken he'd have to explain what it's supposed to do in the first place, and then he'd be admitting that your complaints about him were true. He can hardly complain "hey, they broke my illegal noise making machine!"
