Anyone know how to make a freestanding sound-emitting device to stop a neighborhood barking dog? Answered

My wife and I just purchased a home and we found out one of the neighbors have a couple dogs that bark all day and into the night. I suffer from migraines and these things are driving me crazy! We have talked to the owners very politely and they don't seem to care. I would love to make a freestanding sound-emitting device that I can direct in the directions of the neighbors fence. Can anyone point me to a instructable  or something that explains how to make one. I know I can buy one for like $75 but I would love to learn how to make one and maybe be able to have more control over how it's used. Any help would be greatly appreciated.

Going Crazy!


The anti barking dog cd works the best. I still use it after all of these years when the dogs start to get out of hand! You can get it at http://antibarkingdevice.com

Once you train the dog in a couple of days, you dont need it for a while. Great product and works fast.


For me the commercial bark sensor/ultrasonic dog thing didn't work either. Then I got some Piezo tweeters connected them to a old stereo amp and used a MP3 sound file of a high frequency tone comming out of a old MP3 player. I cranked it to full volume. This made the barking dog run into it's garage and he stays quiet for about an hour. I turn it on only long enough to send him running which is only about a second. I have a ON button run to my kitchen window. I think this is probably many times louder than that automatic thing you can buy that has poor results.

I got the stereo amp at Goodwill for $10.00. The I connected 4 speaker in parallel to both the Right and Left speaker connections. The speakers were only $2.50 each on Amazon.com. I mounted them on sticks just over the edge of the fence and wrapped them in thin plastic for rain protection and so that no one knows what they are. The MP3 sound file I made from the free ware program Audacity which is a audio file editor which can output in MP3 format. It has a function that you can create a tone just define what frequency you want. You can make any tone or condemnations of pulsing tones. I made several files to see which worked best and most worked fine, I think it is the volume not the tone that gets the dogs but I wanted something people couldn't hear. I'm now using a 17KHz square wave. I read that the physics of a Peizo responses better to the square wave.

This dog is about 30 to 40 feet from the speakers and keep in mind distance matters.

I also found that if the speaker wire is to long an oscillation sets up between the speaker and the amp and a harmonic sound is produced that you and anyone (your neighbor) can hear. If the wires are not to long it's perfectly quiet.

Keep in mind that even though you can't hear it, IT CAN HURT YOUR EARS and damage you hearing if exposed to it for to long. Don't use it if children will be exposed, their ears are particularly sensitive. If you don't heed this warning you will get the feeling like you have been to a rock concert, both the pain in the ears and that typical ringing that becomes very apparent when you lay down to sleep, and it doesn't take long to get this effect. Only about a minuet for me.

Thank for your blog. I'm going to try your solution. I have tried the best of the commercials and they don't work as the distance is the issue. I'm looking at 75-100 ft. My Son has a 20watt PA unit he wants me to try. You mentioned cheap speakeres but I'm concerned about ohms and how much power a speaker can handle. Can you provide a little more intel on your speakers?

75 - 100 ft is a long way you will have to see if it is effective at that distance. There is a good chance it works. I get the feeling that it isn't necessarily the loudness that shuts up my neighbors dog as much as it irritates him like fingernails on a chalk board.

The 20 watt amp seems small but give it a try. If you shop for one at Goodwill there is usually a half off sale a couple times a month.

As for the specs on a piezo tweeter, piezos are much different than typical speakers. Although they rate them in 4 or 8 ohms like a standard speaker this not accurate. Don't worry about this sec. Piezos are more like a capisitor rather than a resistor so at low frequencies they have very high resistance (impedance) and at high frequencies they have low resistance. We are operating at a high frequency with dog sounds. The only thing to caution against is putting a DC voltage on the piezo for very long. That may damage them. You probably won't damage the piezo by putting excessive power into them, More likely you my damage your amp if you run them to at max power on very high frequencys for long periods of time since this will produce heat in the amp.
Shopping for a speaker? I question the accuracy of the manufacture specs. With that said, the SPL (sound pressure level) is the loudness of a speaker abd is given in Db. A SPL of 93dB to 97dB is typical for this spec . This is what you want the most of so consider SPL the main spec to shop for. Also when judging this spec know that three dB is considered twice the sound power so there is a big diffrence between 93 and 100dB.
As for other specs: The "frequency response" is often given on piezos from ~5KHz to 20Khz. Don't worry about this spec. Any piezo will go much higher. They usually say the top end is 20KHz because 20KHz is commonly accepted as the top of human hearing (why spec it higher). I'm 51 years old an I can't hear above 12KHz, my teenagers can hear to 15KHz.. You can test you self using the freeware program Audacity http://audacity.sourceforge.net/download/ With this you can make sound files with various frequency tones and see if you can hear them. Computer speakers usually have piezos in them and work well for the test.
Just saw a great one on amazon.


Re: How I Got My Neighbor's Dog To Stop Barking!

I recently had a really bad situation involving my neighbor's dogs and their barking. I work at night and sleep during the day when people usually don't pay attention to their barking dogs.

I asked my neighbors to quiet their dogs down and they agreed. The dogs are still barking at about the same rate so I am sure that they did not take me seriously.

After weeks of not being able to sleep, I decided to check the internet and found a lot of people that recommended "The Barking Dog CD".

To make a long story short, I popped the CD into my CD player and the dogs stopped barking almost immediately. As on person stated "I almost fell out of my chair when the dogs stopped barking". I totally agree with them. It worked like a charm. The website is at http://www.antibarkingdevice.com if you are interested.

This method should also work on your own dog if you are having problems with your dog. I certainly hope that I was helpful to you.

bark off units they are avail. at www.barkoff.com. 2 units for 10 bucks. the only catch is you pay s&h for the second unit. but 2 units for 24 bucks(incl. the 14 shipping) isnt too bad. idk thier range but itll shut them up. just waterproof one unit and get a 9 volt battery eliminator(also waterproof that box with silicone caulk locking door with gasket will work. place it as close to the border fence as possible youd just either have to dig or string a wire for the source unless you want to keep changing 9 volts out every day or so. also putting a barkoff and a condensor mic DIRECTLY in the path with an amp maybee 10 watts and a supertweeter will amplify the sound further again anything thats outdoors is to be watertight and have an access door(if you ever plan on repairing things) just a few suggestions

Crappy neighbors are everywhere! I have one that couldn't care less about their barking k9.


I'm working on an ultra-sonic "trainer" that uses one of the bark controlers on the market as a triggering and signal source for a horn loaded, ultra-sonic emitter.


Here is the bark controller that I'm looking at. . . http://www.ultimatebarkcontrol.com/howitworks.htm This might work as a stand alone but my situation calls for more amplitude due to the distance that I have to work around.


I'm going to try the above unit but if it doesn't do the trick alone I will buy the following set up and use the ultimatebarkcontrol as a trigger and sound source for this amplifier/transducer/horn.

The ultimatebarkcontrol is about $100.

 The amp and speaker will be about $150.

 Peace and quiet. . . Pricless

Yikes, I used to suffer from migraines too. The best thing I can suggest is to get yourself some disposable ear plugs.  Also, if you can buy a sheet or two of Styrofoam insulation and cut them to fit into any window openings in the room.  Leave them in a closet until you need to block out the exterior noise. It will also help to pull the drapes as a sound dampener, and darken the room, which I always found imperative when I was having a migraine.
I hope you get some relief, I know where you're at.

I don't know of too many sounds that will *stop a dog from barking, aside from another bark that causes them pause while they decipher the gossip. If, on the other hand, you want to *cause all the dogs to Start barking, a loud note in the range of 15-20KHz will get 'em going really nicely.

If you have a pool pump, you might turn it off at night. Dogs have sensitive hearing an may simply be responding to the motor noises of surrounding equipment. (My furnace produces a steady state ~14KHz sound while running, and it drives me right up the wall when I turn off the tv/radio/other and it becomes isolated)

Most communities have noise ordinances. If your neighbors fails to control their dogs, it may be that you'll have to resort to a legal complaint to the authorities.

Making one probably won't be any cheaper than buying one. This is something you might find but it's not a common build.


Do you not have a sound ordinance in your town?

You could try a very high pitched sound.   If you can get a high powered tweeter, high powered amp and an audio generator.  At around 20k hz you should not be able to hear it so crank it up and aim it at the dogs.  Vary the setting until/if you find a setting that seems to irritate the dogs.  It may just make them bark more.

Even though you can't hear the sound it is still going to do hearing damage if it has enough power so wear hearing protectors if you're going to use it for long.

What crappy neighbors you have!
