The frequency of most dog whistles is within the range of 23 to 54 kHz, [5] so they are above the range of human hearing, although some are adjustable down into the audible range. To human ears, dog whistles only emit a quiet hissing sound. [ 6 ]
Hearing range describes the frequency range that can be heard by humans or other animals, though it can also refer to the range of levels. The human range is commonly given as 20 to 20,000 Hz, [ 3 ] [ 4 ] [ note 1 ] although there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to ...

A dog whistle is a whistle that emits ultrasound, used for training and calling dogs. The frequency of most dog whistles is within the range of 23 to 54 kHz. [25] Toothed whales, including dolphins, can hear ultrasound and use such sounds in their navigational system to orient and to capture prey. [26]
A range of over an octave is possible, but whistle vary in the range of pitches and loudness they can produce; [2] Denser material typically have greater ranges. [2] [10] When a dog is trained to voice commands, whistle commands are added in parallel; when the dog is responding to the whistle commands, the voice commands can be omitted.
I've read that a dog's hearing range extends up to 45 kHz, so I would guess an ultrasonic dog whistle would have a frequency of somewhere between 20kHz and 45kHz. Interesting question. The dog article quotes these numbers for hearing (which numbers vary depending on my source; I'm going to re-edit that section of the article)): dogs hear in the ...
These devices are whistles that do not radiate sound, but are still aerodynamic whistles. The upper figure on the right shows the basic arrangement of one version of the device. The circle on the left is the fluid source (air or liquid). A jet is formed that either goes into the upper or lower channel. The black lines are the feedback paths.
The whistle register is the highest phonational register, that in most singers begins above the soprano "high D" (D 6 or 1174.6 Hz) and extends to about an octave above (D 7 or 2349.3 Hz). It is created by using only the back of the vocal folds .
