What Frequency Can Dogs Hear? Dogs can hear sounds that are way beyond what humans can. While humans can hear sounds between 64 Hz and 23,000 Hz1, dogs can hear sounds from 67 Hz up to 45,000 Hz1. This lets them detect high-pitched sounds that are crucial for hunting small rodents.
Dogs have 18 muscles in their ears, while humans have only 62. This difference helps dogs move their ears to pinpoint sounds better. They can hear soft, high-pitched sounds that humans can’t, making them experts in hearing.
Key Takeaways: What Frequency Can Dogs Hear?
- Dogs have a significantly wider hearing range compared to humans, able to detect frequencies from around 40 Hz up to 60,000 Hz.
- This enhanced hearing capability is a result of dogs’ predatory heritage, as their ancestors the wolves needed to detect high-pitched sounds to hunt small rodents.
- Dogs have 18 muscles in their ears that allow for precise movement and localization of sounds, compared to only 6 in humans.
- Dogs can hear sounds as high as 47,000 to 65,000 Hz, while the average adult human cannot hear sounds above 20,000 Hz.

Understanding Dog Hearing Capabilities
Dogs have amazing hearing that is much better than ours. They can hear sounds from 40 Hertz (Hz) to 60,000Hz, while we can only hear up to 20,000Hz3. This special hearing helped their ancestors, wolves, catch small rodents by hearing their high sounds3.
Frequency Range and Sensitivity
Dogs can hear quieter sounds than humans, starting from -15 decibels (dB)3. This means they can pick up sounds we can’t hear. It helps them hear things from far away that we miss.
Predatory Heritage and Evolutionary Advantages
Their great hearing comes from being top predators. Dogs have 18 ear muscles, more than humans’ 63. This lets them move their ears to find sounds easily4. Wolves used this skill to hunt small rodents, and dogs still use it today.
This special hearing has helped dogs a lot. They can hear sounds we can’t, like those between 23,000Hz and 25,000Hz3. This helps them know what’s happening around them, find threats early, and catch prey from far away4. Their great hearing has made them very successful and adaptable.
“Dogs have a superior hearing range compared to humans, making them susceptible to discomfort from high-frequency sounds.”
Measuring Auditory Perception in Dogs
To understand a dog’s hearing, scientists use special tests. They use behavioral tests and the Brainstem Auditory Evoked Response (BAER) test5.
Behavioral Testing Methods
Behavioral tests teach dogs to do actions when they hear sounds. This shows how well they can hear different sounds and how loud they need to be5.
Brainstem Auditory Evoked Response (BAER) Test
The BAER test checks the brain’s response to sound without surgery. It uses electrodes on the head and earphones to play sounds. The brain’s activity shows if the dog can hear5.
These tests help us understand how dogs hear. They show how their hearing helps them in hunting and survival56.
Hearing Ability | Humans | Dogs |
---|---|---|
Frequency Range | 20 Hz to 20,000 Hz | 47,000 Hz to 65,000 Hz |
Hearing Threshold | -5 dB to -15 dB | -5 dB to -15 dB |
Directional Hearing | Moderate | Superior |
Sensitivity to Distant Sounds | Moderate | Superior |
Hearing Through Barriers | Moderate | Superior |
“Dogs have a heightened sense of hearing compared to humans, with a lower hearing threshold and the ability to pick up softer sounds.”6
High-Pitched Sounds and Ultrasonic Frequencies
Dogs have an amazing ability to hear high-pitched sounds and ultrasonic frequencies. Humans can hear up to 20,000 Hz, but dogs can hear sounds as high as 50,000 Hz, maybe even up to 65,000 Hz7. This lets them hear the high sounds of small rodents and human-made sounds like dog whistles, which are too high for us8. Their great hearing helped them in the past when they were predators, letting them find prey or threats that we can’t hear7.
Ultrasonic sounds, which are too high for humans to hear, are not lost on dogs8. These sounds can come from things like bat calls, rodent sounds, wildlife cameras, and some electronic devices8. Some devices, like ultrasonic bark collars, also use these high frequencies8.
This special ability to hear high and ultrasonic sounds gives dogs a big edge in their world. It helps them detect threats and find food that we can’t hear, making it easier for them to survive7.
But, using ultrasonic sound devices on dogs for training or to keep them away is a debated topic8. Some think they work well, while others worry about their effects8. It’s smart to talk to vets before using these devices on our dogs78.
Comparison to Human Hearing Abilities
Dogs can hear sounds at a wider range than humans, but humans have their own strengths in hearing. Humans can hear sounds around 2,000 Hz best, which is the range of human speech9. This helps us understand speech clearly. Dogs, on the other hand, can hear sounds up to 8,000 Hz, great for hearing high-pitched sounds from prey9.
Humans are also better at finding where sounds come from, with a 1-degree accuracy. Dogs can only tell sounds apart by 8 degrees9. This skill helps humans move around safely and know where sounds are coming from.
Maximum Sensitivity and Speech Frequencies
Humans can hear sounds up to 20,000 Hz, but this drops to 12,000 Hz as we age. Dogs can hear sounds up to 45,000 Hz9. Humans can hear the lowest sounds around 20 Hz, while dogs can hear sounds as low as 67 Hz9. Humans can pinpoint sounds to within 1°, while dogs need 4° accuracy9. Dogs can hear sounds 13–19 decibels softer than humans in certain frequencies9.
Dogs are great at telling different pitches and rhythms apart. They can tell tones between 2,820 and 2,900 Hz apart9. They can even notice tempo changes of just 2 beats per minute9. While we don’t know much about their sense of sound quality, studies suggest they can tell different sounds apart9.
In conclusion, dogs have a wider hearing range, but humans are better at understanding speech and localizing sounds. These differences show how unique the hearing abilities are for dogs and humans91011.
Anatomy of a Dog’s Ear
Dogs have amazing hearing thanks to their unique ear anatomy. They have 18 muscles in their ears, compared to only 6 in humans12. This lets them move their ears to catch sounds better. They can even rotate their ears to focus on sounds.
Muscles and Ear Movement
A dog’s ear muscles and sensitive hearing make them great at hearing sounds. They can hear sounds that humans can’t, like ultrasonic frequencies12. Their ears are also super sensitive to touch, making them very responsive.
Some dog breeds are more likely to be born deaf, like Australian cattle dogs and Dalmatians12. This is because of genes related to their coat color. Dogs with certain coat patterns might have trouble hearing because of poor blood flow to the cochlea12.
As dogs get older, they might lose their hearing, just like humans do12. The shape of their ear helps keep it clean, but they still need regular care to avoid infections12.
Dogs have different ear types, like erect or drop ears, depending on the breed12. Some breeds need their ear hair trimmed to help prevent infections12.
Ear problems like aural hematoma can happen in dogs, needing treatment12. If a dog’s ears smell like corn chips, it might mean they have an infection and need cleaning12.
Dog ears have glands that send out pheromones, helping dogs know each other and recognize their mom12. The vagus nerve in their ears makes them sensitive and helps them relax when their ears are rubbed12.
Characteristic | Dogs | Humans |
---|---|---|
Hearing Range | Up to 45,000 Hz13 | Approximately 20,000 Hz13 |
High-Frequency Sound Sensitivity | Lower sensitivity for dogs with wider heads13 | – |
Age-Related Hearing Loss | Small dogs may not show signs until 9 years old, while larger dogs may exhibit signs as early as 6 years old13 | – |
Hearing Loss Prevalence | Large dogs are more prone to earlier age-related hearing loss compared to smaller dogs13 | – |
“The complex musculature of a dog’s ear, combined with their sensitive hearing receptors, gives them a significant advantage in detecting and responding to a wide range of sounds in their environment.”
What Frequency Can Dogs Hear?
Dogs can hear sounds from as low as 40 Hz to as high as 60,000 Hz14. This range is much wider than what humans can hear, from 20 Hz to 20,000 Hz14. Dogs can pick up sounds we can barely hear, and they can also hear ultrasonic sounds that we can’t hear at all14.
This special hearing helps dogs understand their world better. They can hear the high-pitched sounds of small rodents and the low sounds of distant threats14. This lets them react faster and more effectively to what’s happening around them.
Animal | Hearing Range |
---|---|
Humans | 20 Hz – 20,000 Hz14 |
Dolphins and Bats | Over 100 kHz14 |
Elephants | 16 Hz – 12 kHz14 |
Whales | 7 Hz – Infrasonic14 |
Cats | 55 Hz – 79 kHz (Most acute 500 Hz – 32 kHz)14 |
Dogs | 67 Hz – 45 kHz14 |
Bats | 15 kHz – 90 kHz14 |
Mice | 1 kHz – 70 kHz (Distress calls at 40 kHz)14 |
Some animals like dolphins, bats, and whales can hear even more than dogs14. Dogs’ hearing is still very wide, helping them move through their world and respond to sounds. This makes them very aware of what’s happening around them.
“Several users have reported that smart home electronics emitting high frequencies can cause stress to dogs, indicating that dogs are sensitive to high-frequency noises.”15
Not all dogs react the same way to high-frequency sounds, but many can be affected15. This shows how important it is to think about dogs’ hearing when designing places and technology that might impact them.
Noise Sensitivity and Hearing Protection
Dogs have amazing hearing, picking up sounds from 47,000 to 65,000 Hz16. This means they can hear things we can’t. But, it also makes them more sensitive to loud noises. Sounds like vacuum cleaners or power tools can scare them easily16.
Noise Anxiety and Hearing Loss
About one-third of dogs get anxious because of noise, out of 13,700 studied16. This anxiety can come from being too sensitive to sounds. If dogs hear loud noises too often, they might lose their hearing16.
Dogs can be scared of noises for many reasons, like their health, past experiences, breed, and age16. Being scared of one noise can make them anxious around other sounds too. This can make them more stressed16.
Some dogs are naturally more sensitive to noise, and this can start when they’re very young16. Not being socialized well can also make dogs more sensitive to noise16.
To keep a dog’s hearing safe, owners should use special earplugs when they’re around loud noises17.
Applications of Canine Auditory Acuity
Dogs have amazing hearing skills that go way beyond just keeping them safe. Their sharp hearing is super useful, especially in their old hunting days18.
Hunting and Prey Detection
Thanks to their super sensitivity to high sounds, dogs can catch small animals like mice by hearing their quiet sounds18. They can also find where sounds come from really fast, which helps them hunt better18.
Sensing Distant Sounds and Danger
Dogs use their great hearing to pick up sounds from far away, like cars coming or dangers19. They can hear what we can from twice as far away20.
With their amazing hearing and understanding of human language and feelings, dogs make great listeners and friends20.
“Dogs have a sense of hearing about four times as sensitive as humans.”19
Hearing Threshold Measurements in Dogs | Frequency (kHz) | Hearing Threshold (dB SPL) |
---|---|---|
Threshold at 0.5 kHz | 0.5 | 19.5 ± 2.8 |
Threshold at 4.0 kHz | 4.0 | 14.5 ± 4.5 |
Threshold at 20.0 kHz | 20.0 | 8.5 ± 12.8 |
Age-Related Hearing Loss in Dogs
Dogs, like humans, can lose their hearing as they get older. This is called canine presbycusis21. As they age, the parts in their ears can break down. This makes it hard for older dogs to hear high-pitched sounds, like their owners’ voices or a leash jingling22.
There are ways to help older dogs with hearing loss. Using hand signals, visual cues, and special hearing devices can help them. Regular vet visits can spot and treat hearing problems early, keeping their life good2122.
Age-related hearing loss in dogs starts with high-frequency sounds and can get worse22. It mostly hits senior dogs, but younger dogs can lose hearing too because of health issues or genes22.
Things like loud noises, ear infections, injuries, and wax buildup can hurt a dog’s hearing22. To prevent this, keep them away from loud sounds, use protective gear, and take them to the vet regularly22.

Understanding and acting on hearing loss in aging dogs helps them live better. Pet owners can make sure their dogs keep enjoying life22.
“Caring for our senior dogs’ hearing health is just as important as caring for their other needs. With the right support, they can continue to thrive and enjoy their golden years.”
Canine presbycusis is common and needs attention from pet owners. By being informed and taking steps to prevent it, we can help our dogs keep hearing as they age2122.
Conclusion: What Frequency Can Dogs Hear?
Dogs have amazing hearing that lets them pick up sounds we can’t hear. They can hear from low rumbles to high ultrasonic sounds23. This skill comes from their hunting past, helping them catch small prey and react to sounds around them23. While dogs beat us in hearing in many ways, humans are better at pinpointing where sounds come from24.
Knowing how dogs hear is not just interesting but also important for pet owners. As dogs get older, they might lose some hearing ability25. They can hear sounds up to 60,000 Hz, way more than humans can25. This lets them hear things we can’t, giving them an edge in the wild23.
In summary, dogs have special hearing skills that have evolved over time. Learning about these abilities helps us care for our dogs better. It makes us better friends and supporters of our furry friends.
