Need device to stop dog barking

[musiclistener]

I need to make an ultra sound emitting device to stop the neighbor's dog barking. I understand that I need a Piezo tweeter, tone generator, and amp. What are the exact parts I should get and how do I assemble this.

Buy a big bag of Milky Bone and become his friend. It is very effective.

Search the forum. There was a long thread on this subject about 2 years ago. Can't rememeber which section, tho. Might have been here.

I have schematic of such a device.
It was originally made to scare some animals away, that eat you cables in your car.

High frequency generators will not disturb people.
Because we have a very limited hearing range = 'the audio band'.
This is also why 'listening tests' with 'golden ears' can be so very invalid.

Now, cats & dogs and bats & horses has got a different extended audiable spectrum from man.
From the human spieces.

This is why you should use your domestic cat to listen to your amplifier
and tell you if there was any improvement.

You could easily build such a high frequency Generator.
That takes the input = a dog barking
and puts out a PUNISHMENT SOUND response.
It will, in best caes, hurt that stupid dogs ears very much

I've once used a 555timer,with a pot to vary the frequency from 15-30khz,or so.. squarewave output feeding a HOT salvaged from an old TV set,a Motorola piezo horn,and a 9V battery.
Very simple,and it worked well.
Of course with the 9V battery the output wasn't huge,and it wouldn't run for terribly long,but it did annoy animals,and humans.

Piezo horns are perfect!
for this important job ...

Iowa, such a lovely state

What a nuisance, i would suggest a Marlin 45/70, one round out of this should put an end to that pesky barking

Thanks for your input. I confess I know nothing about audio, schematics or electronics. I registered on this website to get some help. I am seeing different methods and parts for building this device. So I am already a little confused. Can I make this myself or should I pay someone to do this? Maybe I can learn to read schematics. Is there any one person on this forum that has the most experience with these devices?

The most difficult to arrange, as I see it,
is to electronically detect the dog barking.

Because I suppose you wont have it scaring that animal all the time.
What is your idea of operation?

Should it be manually operated?
= when you are at home and hear that doggy
you press a button until he gets into coma or throw up .

There are FREE software tone generators. Just hook your computer up. You can set the frequency.
