[3] 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 ...

[6] While wolf barks tend to be brief and isolated, dog barking is often repetitive. [7] One hypothesis for why dogs bark more than wolves is that dogs developed vocal communication as a result of their domestication. [7]
As dogs hear higher frequency sounds than humans, they have a different acoustic perception of the world. [24] Sounds that seem loud to humans often emit high-frequency tones that can scare away dogs. Whistles which emit ultrasonic sound, called dog whistles, are used in dog training, as a dog will respond much better to such levels. In the ...
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 ...

Thirty-seven women ages 18 to 21 were first screened into two groups: fearful of dogs and non-fearful of dogs. [14] Next, each woman was given a questionnaire which asked if she had ever had a frightening or painful confrontation with a dog, what her expectation was upon encountering a dog (pain, fear, etc.), and subjectively, what was the ...
