What You'll Learn
Dogs can hear ultrasonic frequencies
Dogs have a much better sense of hearing than humans. Their ears are more mobile, and their ear shape also contributes to their superior hearing ability. Dogs can hear sounds as high as 50,000 Hz, with some sources claiming they can hear up to 65,000 Hz. In comparison, humans can typically only hear frequencies up to 20,000 Hz. This means that dogs can hear ultrasonic frequencies that are inaudible to humans.
Ultrasonic sound refers to frequencies higher than the normal range of human hearing. These sounds can come from various devices, including household objects like ultrasonic humidifiers. While the frequencies produced by these devices are often too high for dogs to hear, there is a chance that your dog can hear them.
The use of ultrasonic sounds for dog training has sparked controversy. Some people advocate for these devices, while others believe they are inhumane. The concern arises from the unknown frequencies and volumes of the ultrasonic sounds emitted by these devices. If the frequency is very high and the volume is loud enough, it could potentially hurt a dog's ears. Negative-reinforcement training, which relies on unpleasant sounds, is generally considered less effective and less humane than positive reinforcement training.
Some dogs may show signs of discomfort or agitation when exposed to ultrasonic sounds. They may walk with their tails between their legs, tilt their heads, put their ears down, or exhibit tense jaws. Additionally, they may appear scared or agitated, pacing or reacting to sudden loud noises. However, it is important to note that not all dogs react to ultrasonic sounds, and some may be unaffected or unable to hear them.
Overall, while dogs can hear ultrasonic frequencies, the potential for harm depends on the sound pressure level and duration of exposure, rather than solely on frequency. It is important for dog owners to be cautious and observe their pets' behaviour when introducing devices that emit ultrasonic sounds into their homes.

Ultrasonic sounds can be irritating to dogs
Dogs have a much higher frequency range of hearing than humans. While humans can hear sound frequencies up to about 23,000 Hz, dogs can hear sounds up to 45,000 Hz. This means that dogs can hear ultrasonic frequencies that are inaudible to humans.
Ultrasonic devices, such as those used for dog training or pest repellent, emit high-pitched sounds that are inaudible to humans but can be heard by dogs. These devices are marketed as safe and humane alternatives to electronic shock collars. However, there is controversy over whether these devices are truly safe and humane for dogs. Some people believe that ultrasonic devices can be aversive and cause discomfort or distress in dogs.
It is important to consider the potential risks associated with using ultrasonic devices around dogs. While ultrasonic sounds may not cause direct ear damage, they can still be irritating and aversive to dogs. Additionally, the decibel range of these devices may be damaging to dogs' hearing over time, even if the specific frequency is not harmful.
If you have a dog and are considering using an ultrasonic device, it is advisable to be cautious and observe your dog's behavior. If your dog seems agitated or bothered by the device, it is best to discontinue its use. There are alternative training methods that do not rely on aversive stimuli, such as positive reinforcement with treats and praise, which can be more effective and humane.

Ultrasonic devices can cause discomfort
Dogs have a much higher frequency range of hearing than humans. While humans can hear sound frequencies up to about 23,000 Hz, dogs can hear sounds up to 45,000 Hz. This means that dogs can hear ultrasonic frequencies that are inaudible to humans.
Ultrasonic devices, such as those used for dog training or pest control, emit high-pitched sounds that are intended to be aversive to dogs. These devices may be used to deter barking or to keep dogs away from certain areas. The idea is that the high-frequency sound will be unpleasant or irritating to the dog, but not audible or harmful to humans.
However, there is a concern that these devices may cause discomfort or distress in dogs. Rain Jordan, a professional dog trainer, describes the sound emitted by these devices as "punishing" to dogs, as it can startle them or cause discomfort. Furthermore, there is a risk that suppressing normal dog behaviors, such as barking, may lead to learned helplessness or unexpected aggression.
Additionally, there is a possibility that ultrasonic sounds could hurt a dog's ears if they are loud enough. The important factors in causing ear damage are the sound pressure level (SPL) and duration of exposure, rather than just the frequency. While ultrasonic frequencies may attenuate quickly and have a limited range, there is still a potential for harm if a dog is exposed to loud enough sounds over a prolonged period.
Some dog owners have reported signs of discomfort and distress in their dogs after using ultrasonic devices, such as teeth chattering and agitated behavior. In some cases, turning off the devices has resulted in the disappearance of these symptoms. However, other dog owners have reported no noticeable effects on their dogs, even after prolonged use.

Ultrasonic devices may not be effective
While ultrasonic devices are designed to deter unwanted dog behaviours, there are several reasons why they may not be effective. Firstly, there is a lack of standardisation among these devices, and they often do not specify the sound frequency they emit or the hertz level. This ambiguity can be concerning because a very high-frequency sound could potentially damage a dog's sensitive hearing.
Ultrasonic devices are also not consistently effective across all dogs. High-frequency sounds can dissipate rapidly over short distances and are easily blocked by obstacles, so it is uncertain how much sound is actually reaching the dog's ears. Additionally, some dogs may develop anxiety or hearing sensitivity when exposed to ultrasonic sounds repeatedly, leading to negative associations with the sound.
Another reason why ultrasonic devices may not be the best option is that they do not address the root cause of the unwanted behaviour. For example, if a dog is barking excessively, it may be due to underlying issues such as frustration or a lack of stimulation. In such cases, aversive training techniques that rely on discomfort may not effectively resolve the behaviour in the long term.
Furthermore, there is a growing consensus among dog trainers that aversive training techniques, such as those employed by ultrasonic devices, are less effective than positive reinforcement methods. Positive reinforcement techniques, such as treats, praise, and extra love, can build a strong relationship between the owner and the dog and lead to better behaviour without causing discomfort or distress.
Finally, ultrasonic devices may not always provide accurate feedback on their effectiveness. Since the sounds they emit are inaudible to humans, it can be challenging to determine if the device is working correctly or if the batteries need replacement. This uncertainty may lead to inconsistent use or incorrect assumptions about the dog's behaviour.

Ultrasonic sounds are unlikely to damage dog's ears
It is unlikely that ultrasonic sounds will damage a dog's ears. While dogs can hear ultrasonic frequencies, the important factors in causing ear damage are the sound pressure level (SPL) experienced by the individual and the duration of exposure—not the frequency. Therefore, a noise in the ultrasound range would need to be very loud to cause damage, regardless of frequency.
Ultrasonic devices have become increasingly popular in dog training in recent years. These devices emit a high-pitched sound when they detect a dog's bark or when a person pushes a button. The high-pitched noise startles the dog, punishing any bark that comes out of a dog's mouth. However, there is controversy over whether these devices are safe and humane.
Manufacturers of ultrasonic training devices claim that they are safe and humane. However, animal advocacy organizations like the RSPCA Australia have taken a firm stand against them, stating that "electronic anti-barking devices inflict pain and distress on the animal and therefore should not be used." Laboratory animal behavior studies have also found that ultrasound is one of a range of aversive techniques used to elicit a stress response in a wide range of species, including dogs.
Some dog owners have reported that their dogs did not react to ultrasonic devices. However, others have observed signs of discomfort and distress in their dogs, such as teeth chattering and jumping at sudden noises. Additionally, dogs may exhibit agitated behavior, such as walking with their tail between their legs, tilting their head to the side, or putting their ears down.
While ultrasonic sounds are unlikely to damage a dog's ears, they can still be irritating or scary for dogs. Dog owners should be cautious when using ultrasonic devices and monitor their dog's behavior for any signs of distress.
