Dog Whistle
Play a high-pitched whistle tone from your phone or computer. Choose any frequency from 8 to 22 kHz, then use a steady blast, pulses, ready-made recall and stop patterns, or a sweep to find the pitch your dog responds to best.

A steady tone at the chosen frequency, like holding a whistle blast.
⚠ Start with low volume. Very high tones can be uncomfortable even if you can't hear them well, and long or loud exposure is not kind to pets. Keep blasts short.
How to use the Dog Whistle
- Turn your volume down first, then raise it gradually once the whistle is playing.
- Pick a frequency with the slider or a preset. 8–12 kHz is closest to a classic training whistle; higher settings are harder for people to hear.
- Choose a mode: Continuous for a blast, Pulse for repeated beeps, Commands for recall or stop patterns, or Sweep to test a range.
- Press Play whistle (or hold Hold to whistle for a blast as long as your press). Watch the spectrum to confirm the tone is playing.
- Pair the sound with a reward in training, using the same pattern and pitch every time so your dog learns what it means.
Hearing ranges and what your device can play
| Frequency | Typical people | Dogs | Phone / laptop audio |
|---|---|---|---|
| 8,000–12,000 Hz | Clearly audible, sharp and shrill | Easily heard | Plays well on most speakers |
| 12,000–16,000 Hz | Audible to most, quieter for many older adults | Easily heard | Usually fine, small speakers start to drop |
| 16,000–20,000 Hz | Often heard by children and young adults only | Easily heard | Weaker on phone speakers; better on headphones |
| 20,000–22,000 Hz | Above the typical human range | Heard | Near the limit of 44.1/48 kHz audio |
| 23,000 Hz and up | Not heard | Heard (up to roughly 45 kHz+) | Not possible with standard audio hardware |
Digital audio can only represent frequencies up to half its sample rate (the Nyquist limit). At the common 48,000 Hz rate that is 24,000 Hz, which is why this whistle goes up to 22 kHz. Human hearing limits vary a lot by person and age; the figures above are general guides, not measurements of your ears.
Whistle commands trainers commonly use
- Recall: a series of quick pips (pip-pip-pip), repeated until the dog is on the way. Reward generously when the dog arrives.
- Stop / sit: one single, long blast. Teach it close up first, pairing the blast with a sit you can reward.
- Turn / attention: two short pips to ask the dog to look back at you or change direction.
- Keep it consistent: the same pitch, same pattern and same meaning every time. Everyone in the family should use the same signals.
Getting started
Begin indoors at low volume. Play the recall pattern, then immediately reward your dog when they come to you. After a few short sessions, practice in the yard and gradually add distance. If your dog seems uneasy, lower the volume, move to a lower frequency, or try the dog training clicker instead.
Frequently asked questions
Can dogs hear this whistle if I can't?
Dogs hear much higher frequencies than people, roughly up to around 45,000 Hz or more, while human hearing tops out near 20,000 Hz and usually falls with age. If your speaker can reproduce the tone, a dog can typically hear frequencies here that many adults barely notice. The spectrum display shows the tone is playing even when you can't hear it.
Is this a true silent (ultrasonic) dog whistle?
Not fully. Classic silent whistles work around 23,000 to 54,000 Hz, above what normal phone and laptop audio can play. Most devices output audio at 44,100 or 48,000 samples per second, which limits sound to about 22,000 to 24,000 Hz. This tool offers 8,000 to 22,000 Hz, which is high pitched but may still be faintly audible to children and young adults.
What frequency should I use for training?
There is no single best frequency. Many traditional training whistles are clearly audible to people; they work because the sound is distinct and carries well outdoors. Start around 8 to 12 kHz, which plays well on most speakers. The most important thing is to use the same pitch and pattern every time and pair it with a reward.
Why can't I hear anything at 18–22 kHz?
Two reasons: adult hearing often stops well below 20 kHz, and small phone or laptop speakers lose a lot of volume at very high frequencies. If the spectrum shows a peak, the tone is being produced; external speakers or headphones usually reproduce high tones better.
Will a dog whistle stop a dog from barking?
A whistle alone does not stop barking. It can interrupt a dog's attention for a moment, and trainers use that moment to ask for a known behavior and reward it. Consistent positive training works much better than repeated loud sounds, which can stress pets.
Is it safe for my dog's ears?
Use modest volume and short blasts, like a real whistle. Standard device audio cannot produce true ultrasonic tones, but very loud or long high-pitched tones are unpleasant for animals and people. The tool auto-stops after 30 seconds and stops when you switch tabs to prevent accidents.
