Dog Whistle
Press the button to play a dog whistle. This free online dog whistle makes a pure tone at the frequency you choose, from 1 to 25 kHz, as a steady sound, short pulses or a sweep. It runs in your browser on a phone or a computer, with nothing to install.
Short bursts only. Never hold the speaker near a dog's ear.
What Is a Dog Whistle?
A dog whistle is a whistle that makes a very high-pitched sound. Dogs hear much higher pitches than people do, so a trainer can use one to get a dog's attention without the sound carrying across a park. This online dog whistle does the same job with a speaker. It plays one clean tone, and you decide the pitch, the rhythm and the volume.
Dog Whistle Frequency
Pitch is measured in hertz (Hz), and 1,000 Hz is one kilohertz (kHz). People hear up to roughly 20 kHz when they're young, and the top of that range fades with age. Dogs hear a lot higher, up to roughly 45 to 65 kHz, which is why a tone that is silent to you can still reach them. Training whistles are usually pitched somewhere in the high range, and the exact number matters less than you might think. A dog learns what a sound means, not the number behind it.
One honest limit: phone and laptop speakers, and most browsers, usually cannot play much above 20 to 22 kHz. The settings near 22 and 25 kHz may come out quiet or not at all, and a dog may not hear them either. Real silent whistles run higher, around 23 to 54 kHz. This tool tells you if your device cannot reach the frequency you picked.
How to Use a Dog Whistle for Training
A whistle works as a signal, so pair it with something your dog likes. Blow it, then give a treat or a game right away. After a few rounds the sound means "good things are coming," and that's what you can use for recall. Start indoors, in a quiet room, with a pulse or a steady tone at 10 kHz and the volume low. Keep each session short, and end while your dog is still keen. If you want a bark to practice around, open the dog barking sounds.
Keep the speaker at a distance, never at your dog's ear, and keep the volume moderate. If your dog backs away, pins its ears or seems upset, stop and try again another day, or skip it. For anything about your dog's hearing or behavior, a vet or a trainer can help far more than a web page.
Can Humans Hear a Dog Whistle?
It depends on the pitch and on who is listening. At 4 to 10 kHz everyone with normal hearing hears it, and it's loud and clear. Around 15 to 18 kHz it gets harder, and the older you are, the less you hear. By 22 kHz most adults hear nothing. A lot of the tools called silent dog whistles are only silent to us, which is the point.
Why Some Dogs Ignore a Dog Whistle
A few reasons are common. The dog may not have learned what the sound means yet, there may be a more interesting smell nearby, or the speaker may not reach the pitch you picked. Some dogs are also just calm about new noises. Try a lower pitch, a pulse instead of a steady tone, and a treat every time, and give it a few short sessions before you decide it does not work.
A Friendly Hearing Test for Your Friends
Here's the prank angle. Set the pitch to 17 kHz, press play in a room full of people and ask who can hear it. Teenagers and kids often wince and ask what that noise is, while the grown-ups look at them blankly. Slide the pitch down until everyone agrees they hear it, and you have a quick, harmless age test. This is the idea behind the "mosquito tone." Keep the volume low and the bursts short, and be kind about it. Nobody needs a high-pitched whine in their ears for long.
Questions, Answered
Does this work as a real dog whistle?
It plays a pure tone at the frequency you pick, which is what a dog whistle does. The limit is your speaker. Phones and laptops usually cannot play much above 20 to 22 kHz, so the top settings may be quiet or silent for your dog too. Real silent whistles run higher, around 23 to 54 kHz.
What frequency should I use for a dog whistle?
Start at 10 kHz, which most speakers play well and most dogs and people can hear. Move up in small steps and watch your dog. There is no single right number, because dogs differ and your speaker changes how the tone sounds.
Can I hear a dog whistle?
At 4 to 15 kHz, yes. Around 17 to 18 kHz many adults hear little or nothing, and by 22 kHz most hear nothing at all. Hearing at high pitches fades with age, so a teenager in the room may hear a tone an adult cannot.
Will a dog whistle make my dog bark?
Some dogs look up, tilt their heads or bark at a new sound, and many ignore it. Keep the first tries short and quiet. If your dog seems bothered, stop right away.
Is this dog whistle free, and is there an app?
Yes, it's free, with no sign-up and nothing to install. It runs in your browser on a phone, tablet or computer. The Pranksters app also has a soundboard and a fake call, and it's free on Android.
Is it safe to use around a dog?
Keep the volume moderate, play short bursts, and never hold the speaker near a dog's ear. Stop if your dog seems upset. If you have worries about your dog's hearing or behavior, ask your vet.
For fun and basic training practice only. This tool is not a medical or behavior product, so keep the volume moderate and stop if a dog seems upset.
