Thank you, Andrew, you are too kind. And Dougle thinks you are his new BFF.

I hope you will find my story interesting : A neighbour's rottweiler barked at everything day and night I recorded his bark and used a DAW to lower the pitch. Whenever the barking was a problem I would manually trigger the pitch-shifted recording at just slightly louder than the real bark. "Sub-Woofer" was perhaps never used so literally. The theory was that he would think a bigger dog was asserting dominance. In fact he did shut up and run to the other end of the yard. I felt I had simply translated my message into canine and was fine with that. A similar problem has arisen in my new neighbourhood but I don't want to add audible sound. That's why I checked your video. It's great.

Ralph, I love the fact that you have a complete library for projects that a fellow needs from time to time. Right now I am in need of a dog quieter for my neighbors dogs. The fellow has 3 dogs, two huge ones, a German Shephard that stands on all 4s and his back reaches my hip (I am 6'3") the other a pit bull that looks like he could clean the shepherds clock any time he wanted. The last is a yippy little Pomeranian mix of some sort. They have a 6 foot by 5 foot cage that keeps the dogs in their yard at night, which is where they leave them even when the weather is bad. A tarp covers part of it so they can get out of the rain. Problem is, they like to bark. ALL NIGHT they bark. Now the neighbors like their beer and pot so I doubt they can hear a lot when it comes to bed time, so it is just me and my daughter who now lives in my spare room to take care of dad now that my good wife of 51 years has passed on. We have gone the route of asking politely if they would keep the dogs inside only to be cussed out and called a racist (He is Hispanic.) I have tried the police (they simply pay the 20 bucks and it's done) and even borrowed a friends ultrasound dog determent portable deal which works but you have to be outside for it to get them and, of course when it's sitting around 0F you don't much care to walk around the house to click the button. So I am in hopes of using this video as a beginning to building one like you are putting together. Good luck, I guess we are going across purposes but I think I can make the transformation.

Did you move house? Cut off your ears? :)

So we have an issue that a bark detector would be a good idea. But not to turn on some noise, but to trigger our electronic doggy door. He wears a collar with a little device that constantly puts out low volume ticks at a certain frequency and pattern. As he gets close to the door, inside or outside, it triggers the door to open the doggie door so he can go out or come in. Works a charm and we've had this now for over 10 years (ish). But here's the problem. The ultrasonic sender device uses a CR2530 battery. It lasts several months, but if we're not paying attention, like a few days ago, the batter will go dead. If he's inside the house, then not a huge deal. BUT, if he's outside, then he can't get back in. If it's super hot outside or worse, sub-zero temperatures, he could die. Literally. Like the other day, we were out for a couple of hours and when we came home, we could hear him barking. It's a very distinct bark, that he does at the big people door. LOL So I think a bark detector would be good here so that if this happens, it would just "press" the OPEN button on the electronic door. It's a High Tech Pet Door. So you might think, just easier to use a motion detector, which is easier for sure. BUT "MOTION.... MO...SHUNNNN!!!!!!" Any motion would open the door, motion by ANY animal! Including a skunk! LOL So... bark detector it is!

Before the electronic door, we had just a basic rubber swinging door and we did come home from work one time to find a squirrel going crazy in the house. Oh what fun that was. But better a squirrel than a skunk. LOL So at some time this summer, I'll work on a bark detector. The only issue I can see with it, however, is that sure, it will trigger and open the door, but our little guy isn't the brightest bulb on the tree, so when he barks at the main door, he may not realize that HIS door has opened. LOL I may have to augment this with some flashing LEDS and get him used to them flashing when the door opens or closes. Hopefully, that would solve the issue.

Very absorbing Ralph, thanks. Your video made me do an online hearing test. Anything over 8KHz and I'm buggered! We even have a multimeter at work whose continuity bleeper is outside my hearing range, much to the amusement of my younger colleagues. A professional dog trainer showed me (as another commenter also said) to make my dog bark then reward him, followed by making him stop then rewarding him for that too. It works! My current dog took only minutes to pick this up and will bark if I say "speak" and (usually) shut up when I say "quiet". My dad taught the first dog in my life (all labs or lab crosses btw) to bark when cats were in the back garden to stop them pooing in his flower borders by saying "puss cats" but it backfired on him in a way because at that time there was a great footballer called Puskas and whenever the commentator said his name, it would set the bloody dog off 😂.

I'm thinking now about tensorflow-light or using a spectrum analyser FFT to detect if the harmonics of the dog barking are present in the same ratio. Any advice? Thanks in advance.

They still might not believe you if you create your own project. Better would be to just record the noise using a webcam with a displayed date/time.

Perhaps you keep in mind, the input of the arduino is actually an output delivering a small current in the uA range. Internally the voltage drop is detected by cascaded transistors to detect if the input is pulled down towards low logic level on the outside of the ic or the oppsite, held up to high level, which causes no drop internally. So in general inputs on devices that come with a logic level on its pins are not really "inputs" the way one would expect, but "current drain detectors" instead. But this of course can change calculations for external RC-Filters and the like by some means. p.s. datasheets tell something like " -xx nA/uA" for inputs at low level input to show how much current the input will deliver, when the input is pulled low externally. This needs to be taken into consideration, when the pulling low on the outside of the IC is weak, like pulled through some large value resistor against 0V (relative to the IC current supply).

pps. There is by the way a reason why base(gate for CMOS) is not connected to the input. A logic low level can range up to some voltage of 1.4V (depending on the logic gate family), but this already can drive a transistor/FET into saturation. Such a ciruit would almost all the time have inputs interpreted as logic high level. This is of course not the way things are expected to work, when all the time the same logical level is present. -- Poly-emitter-"inputs" instead behave independendly of such low voltages at logic low level, since the present voltage drop across base/emitter and the resulting current flow across collectoremitter decide about the internal interpretation of the logic state at the input pins.

I don't have an oscilloscope just a basic voltmeter so can't pin-point my problem. When clapping the AO analog input hardly changes, the voltage at the diode output changes by a few mV and never reaches 2.5V. I measure 2.4VDC on the output pin of the mic as if its shorted.

Without a scope it might be very difficult to detect fast transient pulses caused by a clap - DMMs are slow to respond.

What you can do is write a test program to read the *analog* input on A0 and display the output every 100mS or so and see what the Arduino detects (it will range from 0 to 1023).

Basically setup is like you except I add a Wemos D1 running tasmota firmware to the SDA/SCL pins of the Arduino. The Wemos can't keep up with the arduino mic readings so I only transmit the latest loudest bark during a bark period and then transmit 0 when in the quiet period. Learning arduino code to convert the values for SDA/SCL transmission was a challenge; however, this allows me to add the Wemos to my home automation and it is declared as HomeKit CO sensor (notifies when the 'barklevel' is triggered). Works indoors but outdoors isn't great as the mic range is very poor. Now looking for a more decent mic that would pick-up loud barks within 15 metres. Cheers

I already tried several ultrasonic noise repellers and also made some of my own with little effect. Then I saw a video about dogs fearing high voltage discharge sounds and I built a high voltage generator that I activate with a remote control. With a quite big capacitor it produces medium loud discharge bangs but the dogs fear it so much that they both move in their porch and stay there for longer time. I call it a success because I can reduce their barking effectively. That might of course be different with other dogs. With the small remote in my pocket I can activate it any time I hear them barking - and that‘s exactly what is needed. Not so fancy as your idea of a bark recognition but useful enough for me.

Better low noise amplifier is GY-MAX9814. It has selectable gain from 40 - 60 dB (gain to VCC is 40 dB, gain to ground is 50 dB and gain not connected is 60 dB, or maximum amplification). It has AGC (automatic gain control), which is enabled by default. This AGC is not good if you want to record voice for example for KZread videos, so by shorting pins 13 and 14 on the chip, or solder onto nearby resistors that lead to those pins, AGC is then turned off. Instead microphone, it can be used for general purpose amplification. If you need bias free input, then unsolder 2k2 resistor (designation "222"). Operating voltage is from 2.4 V up to 6.2 Volts (I did not risk rising it too much). Inside this voltage range, the amplification is almost the same. EDIT: corrected name of the board, instead GY-MAY9814, it should be GY-MAX9814.

Oh, btw... on this module, microphone capsule is not the best one - it has some bad noise figure, but it may be used anyway. I prefer replacing it with some other microphone capsule, or some other low amplitude audio source.

How did this bark detector/responder work out for you? Did it stop the barking? My dog doesn't bark at the moon. He always reacts to something (cat, possum, squirrel, etc.). Still, the neighbors don't care about that; they only want the barking stopped. A few months ago, I made a simpler system after viewing this video (thanks!), using pitches.h to generate the high frequency sounds and a 5120B Piezoelectric Ultrasonic Tweeter for output. The sound is pretty annoying by randomly setting a ramp-up/ramp-down time and pitch. Then I added a Super Bright Strobe Light Bar that comes on at the same time. In SoCal, we have a coyote problem, so my outside yapper dog is in a large cage in the evening. This limited the variables involved in detecting a bark because proximity was not an issue. Just the intensity of the bark differentiated enough from normal sounds/conversation in order to eliminate false detections. It took only 3 nights to "cure" the barking, and I don't even have it hooked up anymore. I've viewed every one of your videos and appreciate the obvious effort you put into identifying and solving the bothersome details that always arise. That separates you from the pack.

I'm glad you managed to successfully make a version of this dog 🐶barking system, Dick. My dog hated it but just wanted to rip it to shreds. Eventually (after a couple of weeks, maybe) we stopped using it as we didn't want to stress him out, but he's actually better behaved now anyway so maybe it did have the right influence on him? Thanks for your supportive words about my channel, I'm very happy you're finding the videos useful.

For the rest of his life poor Dougle's going to leave the room when someone's coughing or sneezing :-)

@RalphBacon

Ah, no, Johann, it's more intelligent than that. Firstly it has a peak detector which detects (mainly) the loud barks. Then he has to bark twice (or I have to cough loudly twice) within a couple of seconds. All in all it's quite reliable. Normal conversation (even loud stuff) doesn't trigger it at all, not even loud noises from the telly, but his barking definitely does!

While a square wave can be said to have a fixed frequency it is equivalent to a mixture of sine waves of different frequencies. This is why it is not strange that the specs give a range of frequencies - limited not by the resonant circuit but by the distortion and the range that the speaker can handle. As for the speaker not being piezo because it has a cone, a moment's thought should clear that up.

There's a follow up video #132 about the PCB. Between that video and this one you should have all the information. Do look at my Github entries for both videos for sketches etc.

Hello Ralph, I was searching for something that would do exactly what you are doing with this project. All of the logic approach is what I was thinking as well. You mentioned reposting the finished project. Were you able to do that? Also, can you share the final schematic and Arduino sketch? I purchased a tweeter and wanted to use a frequency generator to create the desired, or should I say the undesired signal. The problem dog is probably 300 - 400 meters away. I might be able to put it closer by putting it at the corner of my lot up in a tree. That would drop it down to maybe 250 meters away. I must be honest, I am not electronic savvy, but I am will to learn. I will be watching more of your videos for sure. Thanks for all you do.

Hi Brian. Let me break this to you gently. A tweeter (basically, a loudspeaker designed for higher frequencies) is never going to work for this sort of project, I'm afraid. You need a (waterproof) high frequency transducer that you can really dump some serious current into (to get the volume up). Unfortunately, those high frequency transducers are not exactly cheap. Especially as the dog is some 300-400m away! 😲 If you try this with a tweeter (if that is what you really have) you will either burn it out or no dog will hear anything. Sorry to tell you this, but my months of experimentation with this project has given me all sorts of insights into how these things work.

Ralph; I would think if you record the barking patterns over some time may help to know more about your dog's common behavior under many different events. ie some behavior is ok others not.

@RalphBacon

5 жыл бұрын

We've taken great notice, and it's all territorial behaviour. Someone's at the front door, he's barking "STRANGER, STRANGER, STRANGER". That's fine, initially, but when we command him to stop then he should stop, not continue. If someone approaches us on our dog walks he does the same. Sometimes he ignores people (and other dogs), sometimes his small dog syndrome defensive behaviour takes over. I'm sure he can be trained to improve this but it might be in his nature forever!

Also, to my surprise, an antibark commercial Queenmew product that I recently purchased seems to be working at driving my next door neighbor's dog crazy. He still barks, but at least it's driving him as crazy as the little monster from hell has been driving me. Still too early to tell though where this will go

Dogs are like man they can’t do two things at the same time 😂. A trick to stop dogs from barking is putting a dog candy under his nose. When he stops you can give him the candy. Positive reinforcement is a better way to stop your dog from barking. Other thing to try is to let him bark on a command from there you can teach him to stop barking. Will cost more effort, but it will let him stop barking. As you said before you don’t want to hurt your dog, but using a ultrasonic sound to stop him barking is really the last resort. Love your videos.
