What ultrasonic frequency actually hurts dogs? Answered


I'm trying to make a dog repellent device and I need to know how high I can make it before it hurts the dog, because hurting it is not my intention.

Actually, frequency is only a minor contributor to pain and/or hearing loss. Volume (decibels) and plus duration (time of exposure) are what really cause the most serious damage. For example, it only takes a fraction of a second for a sound at 140 decibels or more to cause serious damage. Whereas, one can endure sound at around 100 decibels for an hour or two with minimal or no damage.
I think the better idea is to create a noise which frightens an animal rather than causes pain or irritation.
A dog trainer I once hired, showed me a trick that is quite effective; put four or five marbles into a large, empty can and cap it. If you shake it vigorously, the noise frightens most dogs and cats so much they cease any aggressive actions.

The volume is what causes the effect.

The reason to operate in "ultrasonic" frequencies is because you/other humans won't be able to hear the loud noise, it is beyond our hearing ability.

These devices can blast away at animals, while we remain oblivious.

Search for what decible range is safe threshold for dogs.

Stick that can on an off-kilter motor, linked to the same sort of PIR detector that triggers garden lights, and you have an automatic animal-scarer.

The elderly in particular use a cat-deterrent in their garden. It is a
small apparatus with a speaker attached to it. It produces a
high-pitched bleep of more than a 100 decibel. The sound is mostly
only audible for children, youngsters and people with ears that are
still good. Many cat-deterrents use the same noise as the Mosquito.
The sound causes pain in the ears, headache, and ringing in the ears.
If you have any complaints consult your GP and make mention of it on
social media!

Working Mosquito: 17KHz-20KHz 90dB
Working Cat Deterrent/Animal Chaser: 16KHz-23KHz 130dB

To be effective you will have to play the frequency through a subwoofer.

( Sorry, that was my attempt at a joke.)
