    Default next door neighbor's dogs

    My next door neighbors have two big dogs that bark and howl all day and night. I have tried telling them about it and asking them to fix the situation but they refuse. Then a few doors down from them is another dog that barks. There is also a few small dogs that live across from me that yap constantly.

    I bought one of those 'bark free' things that emits an ultrasonic sound should to annoy the dogs whenever it detects barking, however it only works for 25 feet. I COULD buy another one for $80+ that would work for 50 feet, but I need something even better than that to go farther and be cheaper.

    I made the 'bark-free' thing go off and placed a microphone next to it. Though I could not hear anything, my computer detected a loud sound. I saved the file.

    Next, I downloaded a free software Oscilloscope. I ran the FILE (without use of my speakers) and it came up at about 20.5Khz. Then, I played the file using my speakers and placed the microphone next to the speakers and tested it using the oscilloscope again. It detected the same frequency but it was about 95% quieter. I tried amping it up but it didn’t help much. I think if I need to play ultrasonic sound correctly then I need special speakers.

    Does anybody know where I can find ultrasonic speakers that plug into a computer?
    Do I need an ultrasonic sound card as well?

    This one’s a toughfy and if you can find the answer, I shall bow down to you…I tried doing research but it just doesn’t seem to be quite in use yet. Please help me, it will be greatly appreciated.

    Google on the internet for the specific hertz that dog whistles are at.

    Then... play it fro yo speakers, you won't be able to hear it, but the dogs sure will... oh... and remember to turn it off at some point, it's really damaging to the dogs hearing.

    sacsourse: did you even read my post? I did that I know the frequency, I recorded it into my computer. Then using a tool that CAN hear the volume of the sound as well as the frequency (surpassing my own abilitys) It detected like no sound being emitted through my speakers, but it did through my file. That means that you need special equipment outside the typical speakers you get at a store.

    I was asking if anybody knew about a SPECIAL pair of speakers that would reach 20-25khz without any loss in volume and still maintain 110 db+. I was asking if anybody knew if weather the bottle neck was either my speakers or my soud card.

    michaelsa : i have a similar problem at my apartment but with birds instead of dogs. i'm wondering if i can design a device like what you are talking about and run it out of a spare computer. i *think* i've found some speakers that output in the 40khz range (http://www.circuitspecialists.com/level.itml/icOid/1059), however your post about the output being in the ~20khz range has me confused. humans can hear up to ~20khz(http://www.enerchecksystems.com/articl14.html) so i'm wondering if the dog repellers would really be that close to the threshold of our hearing. is there any way that your audio program could have a ceiling on the spectrum and so it is just bucketing anything >20khz as 20.5khz?

    regardless i would be interested to find the right solution whatever it is, so feel free to email with any thoughts / questions... ttconrad at gmail dot com thanks!

    Jeez never heard of a telephone? Phone your local council or whatever you have where you live and report it as a nuisance.
    1. They can enforce local law to make the neighbours make an effort in stopping it and remove animals if it persists.
    2. You won't be damaging the dogs hearing. It isn't their fault they're barking, they've just got bad owners. Cruelty to their poor ears is not fair.
