The same frequency wave as a fire alarm.
While dogs can hear high frequency sounds, BATS may hold the record. They use high frequency sound for navigation.actually there are 2. dolphins and miceBeluga Whaleand bats
Some dogs may be bothered by ultrasonic pest repellers due to the high-frequency sound they emit.
So they can annoy you, that's why!
No, it is not recommended to use an ultrasonic pest repeller around dogs as the high-frequency sound emitted by the device may cause discomfort or stress to the dogs.
Different animals can perceive sounds at different wavelengths. For example a dog whistle has a frequency which dogs can hear but is too high for humans. Furthermore, people's sensitivity to sound frequency changes with age. In general, ordinary range for humans is 20 to 20,000 Hz.
Not per se. Echo location requires the animal to emit high frequency sounds then tracking targets by the reflection of that sound. Dogs do not emit high frequency sounds, but do have acutely sensitive hearing, and are able to track by distinguishing the direction from which sound originates.
maybe to annoy people and play with cats and dogs
The sound waves produced by a whistle are at a higher frequency than that of a beaten drum, causing the sound registered by human ears to be at a "higher pitch". Dog whistles can only be heard by dogs because the sound waves produced are at such a high frequency, human ears cannot detect them.
oh my god I'm talking about does it hurt a dogs ears when they hear ultrasound frequency.

The frequency of the sound is too high for humans to hear, but dogs have more sensitve ears and can hear at higher frequencies.
