One of the most popular forms of canine deterrence for a long time was an ultrasonic dog repellent, and such devices were sold on lofty claims of near certain effectiveness and ease of use. As time goes on, though, it’s becoming clear that there isn’t a lot of science backing the technology, and better alternatives have been created as a result. These alternatives make use of audible tones instead, which are actually better at deterring aggressive animals.
An ultrasonic dog repellent may not produce the right kind of sounds to affect aggressive canines reliably, as they lie outside the animal’s sensitive hearing range. And because they produce higher frequency sounds, they fire in a narrow beam width. This makes it harder to aim, which is not what a user wants from a safety device when the adrenaline is pumping.
Devices that use audible tones, like the Sound Defense, are designed to be more effective because the animal responds more quickly. The Sound Defense operates using tonal patterns that are repulsive to dogs, designed to cause them to break pursuit and stop threatening the user. From the moment the Sound Defense is fired, it only takes a fraction of a second to affect the canine, and with its lower frequencies, it is much easier to aim. And because it produces audible sounds, the Sound Defense will alert everyone nearby to the presence of an aggressive animal, possibly preventing injury in others as well.
Animal deterrence has come a long way in recent years, and people can now spend time outside without worrying about aggressive canines, thanks to the Sound Defense.
