Dog WhistleWhy the high-frequency whistle sounds quiet
A high-frequency setting can sound faint because the selected digital frequency and your speaker’s actual output are different things. Many phone and laptop speakers cannot reproduce ultrasonic frequencies. Check playback, system volume, and the visible setting at a low level. Silence alone cannot tell you what a dog hears.
Separate the frequency number from speaker output
Start by reading the current setting rather than judging the sound from the preset you pressed. The page offers 4, 8, 12, 16, and 18 kHz presets. Each is limited by the current frequency cap. A preset may therefore produce a lower displayed value when it exceeds that cap. The minimum is 440 Hz, and coarse adjustments move in 100 Hz steps. These controls describe digital generation. They do not verify the speaker’s response at the chosen frequency. A large number on screen is not proof that the device produces that tone clearly in the room.
- Record the visible value mentally before changing it.
- Treat the cap as a software limit, not a speaker rating.
Check playback without chasing loudness
Keep system volume low while checking the page. Software gain defaults to 10%, with a maximum of 25%. That percentage is separate from your device’s volume setting. Zero gain explains silence even if playback is active. Confirm the chosen control method too: hold mode needs continued pressure, while toggle mode runs until stopped. Try steady mode when checking whether playback starts and ends. Pulse and warble change the sound pattern, which can make casual comparisons less clear. The 10 ms cosine fade softens the start and stop; it is not a speaker test.
- Check gain and system volume as two separate settings.
- Keep the speaker away from ears while checking controls.
Account for stops and output changes
A tone may have stopped because the tab became hidden or audio was interrupted. The app also stops after a devicechange signal. That signal cannot report every possible audio route change across browsers. If you switch between built-in speakers and another output, stop playback yourself first. Check the selected system output before starting again. Use the page control for a deliberate restart. Space can toggle sound, and Escape can stop it, unless you are typing. If you compare another frequency, keep volume low and change one setting at a time. Stop if the sound causes discomfort.
- Return to the visible page before checking playback again.
- Do not depend on automatic detection when moving between outputs.
Read reactions and other sounds with care
An audible clicker does not confirm that a speaker can reproduce a high whistle frequency. Classic and soft clickers are separate sounds, and Quick yap is a synthetic marker. Their audibility cannot validate ultrasonic output. The reaction feature gives a four-second burst followed by reacted or noReaction choices. It saves the last three dated choices locally and includes a clear action. Those choices describe what you observed during those bursts. They are not calibrated measurements. Dogs vary, and the app makes no promise about a response. Avoid repeating louder bursts simply to obtain a different result. Stop the session when the controls have been checked.
- Keep sound checks separate from claims about what an animal can hear.
- Use local outcomes only as records of your selected observations.
- Read the current frequency after selecting a preset, including any reduction caused by the sample-rate cap.
- Confirm steady mode, the hold or toggle setting, and a low system volume before starting a brief playback.
- Check software gain and the selected audio output. Stop manually before changing speakers, headphones, or connections.
- If the high setting remains quiet, accept that speaker output is unverified. End playback without raising volume to force an audible result.
Does selecting 18 kHz prove that my phone produces 18 kHz sound?
No. The preset is subject to the digital cap, and the visible value shows the current setting. Neither the preset nor that value verifies physical speaker output.
Can I use the whistle to check hearing?
The app does not provide a hearing test. It has no microphone measurement, and its reaction choices cannot establish a person’s or dog’s hearing range.
Will choosing a different pattern solve a quiet high tone?
Steady, pulse, and warble change playback patterns. They do not verify speaker response or promise audible output at a selected frequency. Review the controls at low volume instead.
