Sound Defense has created a patent pending dog repellent that uses a sound frequency that is audible to both the canine and the user. This means that the user will, in fact, know that it is on and working. The frequency used is emitted in a series of patterns that are intended to confuse the animal and make them stop their pursuit. This device does not require accuracy of aim either, so a bicyclist, walker or jogger never has to take their eyes off the road ahead of them. This increases the safety of the user, not just from the encroaching dog but also from any potential road hazards.
The ultrasonic frequencies can be heard by dogs up to 150 feet away (for training purposes), and can repel dogs up to 50 feet away.

Perhaps most important, though, is that this dog repellent uses sound that is easy to control and aim at the attacking animal. Ultrasonic devices are tougher to aim, as higher frequencies produce shorter wavelengths, and, therefore, smaller beam angles. No chemicals are necessary either, so there is no risk of accidentally disabling others with the device, nor does the user have to worry about blowback, which is a real concern in high winds. Ease of use may be the most decisive factor in determining user safety, as a walker or biker may only have seconds between the moment they notice the pursuing animal, and the animal closing in on them. A device that uses audible tones is lightweight, can be clipped to a belt or bike, and does not require precise aiming. It can be engaged even while a biker keeps their head forward and their eyes on the road. After all, a deterrent is only a liability if it puts the user at greater risk of crashing into another obstacle. How to Turn Your Laptop Into a High Frequency Dog Repellent

Animal hearing can be damaged by prolonged exposure to loud noises just like human hearing. A combination of high frequency and high volume will cause the most pain and discomfort. At high volumes, frequencies above 25,000 hertz are uncomfortable for dogs and will cause the dog to whimper or run away. This is basically how ultrasonic dog repellents work. Use caution with these as they can be painful to your pets.Dog Repeller mainly based on producing an ultrasonic waves with frequency annoying dogs and be strange for them so they scare from this sound and ran away .basic ...Ultrasound refers to sounds at frequencies above 20 kilohertz. Such frequencies are little different than lower frequencies, except they are not audible to humans and do not penetrate objects very easily. Many animals, including dogs, are capable of hearing frequencies as high as 45 to 67 kilohertz, so they can hear these sounds made by electronic repellents.The key selling point to a dog repellent that uses an ultrasonic sound frequency is that it is inaudible to the user. It uses a frequency that is outside a human’s natural hearing range, but within the canines range. But that point in itself is why the sales of those items and the reviews from the users are not going as well as when they first entered the market. The idea was to keep those that enjoy the outdoors or work outside safe from canines that may want to take a bite out of the individual rather than receive a belly rub. In most situations, it is hard to determine just what the canine’s intention is. If they come running, the canine is either seeking out prey, defending their territory, or wanting to say hello, but in the heat of the moment, it is hard to determine what the end result will be. And no one wants to be on the receiving end of an aggressive canine or have to employ a device that requires the user to be within a particular radius. This is why the is gaining ground.
