An ultrasonic sound is a sound wave that is measured above the normal hearing frequency of humans. Technically this is considered to be above 20,000Hz.
Dogs on the other hand, can pick up much higher frequency (higher pitched) sounds than us humans can, measuring up to 45,000Hz. That’s a whole 25,000Hz more hearing range than human ears (even more for those of us without perfect hearing).
This unique canine capability means that we can make use of devices that utilize this higher frequency range, without causing a disturbance to people.
When it comes to dog bark control, ultrasonic devices are therefore one of the most popular and sought after methods of getting a dog’s attention when excessive barking is taking place.

Best Ultrasonic Dog Bark Control Devices Reviews
If you already know whether you want a handheld or a mountable ultrasonic stop barking unit (or you might need one that covers both), but still aren’t sure which is the right one, continue on below for more details about individual devices.
This guide is based on dozens of hours of research I’ve done to find out which ones are actually working for people, and what ones might not live up to expectations.
Dogtek Sonic Bird House
This bird house design of ultrasonic bark control looks the goods – but does it perform?
It’s clearly made mostly for outdoor use, however the company does make it clear that you can use it indoors as well if you want to. Compared to most other units, it has a good range of adjustment settings, letting you tailor the function to your specific situation and environment.
In total, there are 4 sensitivity settings to choose from. This lets you dictate when the ultrasonic sound will be set off – in other words, how sensitive you want the microphone to be to hearing a dog bark and determining that the bird house should be activated.
Whether you’re using it indoors to help train your own dog to start barking, or if you’re setting up the bird house in your yard to target a neighbor’s dog; you can adjust the settings accordingly because these two situations can have very different requirements when it comes to detecting a dog bark sound, due to both distance and environmental factors (outdoors there may be wind noise, then there’s the distance).
The Dogtek Bird House is built to withstand rain outdoors – so it’s one of the few that you can confidently place somewhere outside that puts it within a suitable distance to where the barking dog is. The amount of rain and moisture the bird house can tolerate however, is debatable. Ideally it should be placed where there’s some protection from constant direct rain, such as under an eave or a sheltered roof.
The Sonic Bird House is powered by 6 AA batteries, and the life you’ll get out of them will mostly depend on how often the system is activated. It sits in stand-by mode when not in use, and in this mode the battery life is considered to be several weeks long. Alternatively, you can switch the device off completely when you don’t need to use it (some people, for example, will only want to activate the ultrasonic sound at night).
To get the best performance out of this device (and any other ultrasonic detection system), you’ll need to place it where there are no or at least minimal obstacles in the “line of hearing” of the microphone. It won’t work through a brick wall or other solid structures and fences, and things like trees and foliage may somewhat hamper its ability to be accurate in detecting a bark all of the time – but these environmental factors will vary in each situation.
Of course, the appearance of this ultrasonic bark controller is really appealing, especially if you want it to both blend into your property and not gain attention from the neighbor who’s dog you might be targeting. It might confuse the local birds for a short time though!
Dog Dazer II Handheld Ultrasonic Dog Deterrent
This is a handheld ultrasonic unit that is small and light enough to take on your walks, as well as using it around the home.
With a range of 20 feet, it’s not a device that’s going to be suited for targeting a neighboring dog that barks excessively (unless you live exceptionally close), but it’s ideal as a training tool for your own dog or as a protective measure when out walking your dog. It can be attached to your belt or elsewhere with the inbuilt clip, so you can have your hands free until you need to use it.
There’s no automatic operation on the Dog Dazer – it’s a fully manual device that you’ll need to activate yourself.
But that’s to be expected with a handheld unit like this as it’s not a passive tool like the Sonic Bird House and other similar ultrasonic that are made to be placed outdoors for long periods of time.
Motorola BARK500U Indoor Ultrasonic No-Bark Deterrent Device
This is a flexible ultrasonic device, as it can be mounted and set to automatically detect barking and activate, or used in your hand as a manual training device and activated by you.
There’s a 5 second delay to the unit activating when it detects a bark – this is to prevent it from going off every single time a dog barks just once or twice.
The idea behind an ultrasonic bark controller is to halt excessive barking, so this is a really good feature to have for several reasons.
Preventing a dog from becoming accustomed to the sound is important, and by only activating (in automatic mode) after 5 seconds of barking, the Motorola BARK500U is being used at only the times it’s actually required.
Needless to say, if you have an ultrasonic sound going off every single time the dog makes a short (and normal) bark of less than 5 seconds, he’ll soon ignore it completely.
Hoont Ultrasonic Dog Repellent and Trainer
There are multiple uses for this handheld unit:
- Used to help stop excessive barking from a neighbor’s dog
- To repel dogs when you’re out walking
- To train your own dog to stop inappropriate barking behavior
- Can also be used as a training tool to stop other unwanted dog behavior like excessive digging
The Hoont has a significantly larger working range than the Dog Dazer II – rated at being able to be heard by a dog at up to 50 feet away.
Keep in mind however, that this is maximum range when environmental conditions are perfect with no obstacles; you may not necessarily get a range of 50ft when using the Hoont.
The unit is relatively large for a handheld device, especially when compared to some of the others in this guide. If being carried in the pocket, it’s probably going to be noticeable in the same way as a large wallet might be.
The company behind this produce does seem to have participated in some fairly aggressive marketing and supplying discounted or free units to people in exchange for reviews – this is something I always like to watch out for.
It doesn’t necessarily mean that the device doesn’t work well, but looking at both sides of the coin I have (through my extensive research across a wide range of platforms) come across a relatively high number of people who’ve had some operational issues with this device; namely that it can tend to malfunction with no sound being emitted when activated.
This is likely due to low quality electronics and connectors.
Overall build quality is something I look closely at and consider a high priority for any product, not only because it determines how well it will work, but how long it will last.
So if there’s a failure or legitimate questions in that area, I lean towards not recommending. With that said, the Hoont does work well for some people, there is no doubt about that.
My conclusion? The Hoont won’t break the bank if you choose to give it a go, but there are other better handheld ultrasonic units out there currently.
Mountain Ultrasonic Bark Deterrent Birdhouse
Another interesting bird house style ultrasonic unit (although I do find the Dogtek a bit better looking personally), this Mountain brand device comes in 2 different colors – light and dark – so you can match it to your desired position and have it blend in well to the environment, whether that be hanging on a tree, fence, or under an eave of the house.
It’s rated to be able to pick up a dog’s bark up to 50 feet away, but as always this will largely depend on environmental factors like any obstacles in the path between dog and birdhouse, and the volume of the dog’s bark.
This ultrasonic unit is ideal for neighbor dog barking problems, but can also be used for your own dog in the backyard as part of a broader training plan.
PetSafe Ultrasonic Indoor Bark Control
PetSafe has both indoor and outdoor ultrasonic bark control models – this is the indoor version.
Unlike some others which are described as being suitable for both indoor and outdoor use, a benefit of the PetSafe products is that each one is specifically designed for use either outside or inside, so you’ll have capabilities fine tuned for either environment rather than a “one size fits all” approach which might fall short in some areas.
Battery life can be an issue with a few of the devices I’ve detailed in this guide, with some only getting a few weeks of battery life. Although it’s not quite as important as an outdoor unit, having an indoor ultrasonic device like this one that has a long battery life is still a benefit; and the PetSafe is rated at lasting up to 6 month with a 9 volt battery. This will of course depend on how much you use it, but expect it to last at least 5 months as a minimum (which is still excellent).
The PetSafe Ultrasonic Indoor can be used either automatically. where it detects barking and activates itself, or as a manual training tool that you activate yourself.
With a 25 foot range, it’s suitable for most indoor areas, but keep in mind that obstacles like walls and closed doors will hamper its performance without a direct “line of sight” between it and the dog. Unfortunately, this is one of the main reasons that people believe that the unit isn’t working properly (or at all).
PetSafe Ultrasonic Outdoor Bark Control
Another cute Birdhouse design, the PetSafe Outdoor Ultrasonic unit has a 50ft range, putting it equal with most other outdoor devices.
There are 2 models: Standard and Deluxe (also called Elite).
Besides the diffrence in appearance, what sets these two apart from each other?
The main and most significant feature is that the Deluxe unit has an inbuilt timer that you can program simmilar to an alarm clock, being able to set the unit on or off at certain times. So if you don’t want it going off during the day at all, you can set it up to only activate at night.
The Standard PetSafe Outdoor birdhouse unit does not have this capability, so you would need to manually switch that one on and off as needed.
Bark Stop Classic Ultrasonic Outdoor Bark Controller
Made exclusively for outdoor use and designed to withstand most weather conditions, the Bark Stop Classic from Aspectek claims to be a “dog silencer” with a big range, that can also repel other animals like rodents, squirrels and even deer.
How does it do this?
Unlike all of the other ultrasonic bark controllers, this one includes not only a microphone sensor, but a motion sensor as well.
This takes it into the realm beyond just being an anti-bark unit, into more of a “pest control” device as well. But even if you have no need or intention to use it for that purpose, does the Bark Stop Classic stand on its own when it comes to stopping nuisance barking? That was the main focus of my research.
There is a mode that you set for barking only, so if barking is the only thing you want to target with the device, you’re able to easily ignore the other features. It’s easy to feel overwhelmed with a device that has multiple capabilities like this, but Aspectek has done a good job of letting you isolate the settings and use the Bark Stop unit for your own specific purpose. This lets you disable the motion sensor and only rely on the bark detection capability of the unit.
Sunbeam Sonic Egg Bark Control Device
The Sonic Egg is designed to be placed in a location, while the Little Egg is a comfortable little handheld device that you can take anywhere.
The rounded shape makes it unique amongst the other handheld units here, and it certainly takes top spot for aesthetics and ease and comfort of holding.
Sunbeam is confident that the unit works on 85% of dogs which is not determined by breed, but by individual animals.
This is better than stating a 100% or close to perfect success rate, although 15% is still a relatively large margin of error.
It’s simply not possible to know how any dog will react to an ultrasonic device until you try it – but the odds are, at least, in our favor with more chance of the dog reacting to it than ignoring it.
