Dogs have long been known for their impressive sense of hearing, but just how far can a dog hear? We humans have the ability to hear frequencies of sound that range from 20 to 20,000 hertz, but a dog’s hearing range is much wider, extending beyond what is audible to the human ear. In this article, we will explore the science behind a dog’s sense of hearing, and how far they can actually hear. We will also discuss how this ability can be used to benefit both humans and dogs alike.
What is the Range of a Dog’s Hearing?
Table of Contents
The range of a dog’s hearing is one of the most impressive senses that canines possess. Dogs can hear sounds that are far beyond the range of human ears, and this has been studied extensively to determine just how far a dog can hear.
Studies have found that dogs can hear sounds that are four times farther away than humans can. To put that into perspective, a sound that is 10 feet away from a human would be heard from 40 feet away by a dog. This is because dogs have a much larger range of hearing frequencies than humans.
How Does a Dog Hear?
Dogs have the same anatomy as humans when it comes to the ear, with the same three parts – the outer ear, the middle ear, and the inner ear. The difference is that a dog’s ear is shaped differently and is more sensitive to sound.
Dogs also have more sensitive hearing than humans. They have a higher number of nerve endings in the inner ear that allow them to detect sound waves more easily. This is why they can hear sounds that are far away and even pick up sounds that are too faint for humans to hear.
What Sounds Can a Dog Hear?
Dogs can hear a wide range of sounds, from low-frequency sounds that humans can’t hear to higher-frequency sounds that are inaudible to the human ear. Dogs can also pick up on certain sounds that humans may not be able to, such as ultrasonic sounds that are used in ultrasonic dog whistles.
In addition, dogs can detect some sounds in more detail than humans can. They can make out the direction of a sound, for example, and can distinguish between two similar sounds. This is why dogs are often used for hearing tests, as they can detect subtle differences in sounds that humans may not be able to.
Do All Dogs Have the Same Hearing Ability?
No, not all dogs have the same level of hearing. The range of hearing in dogs can vary depending on the breed and age of the dog. Generally speaking, smaller breeds of dogs have a higher range of hearing than larger breeds.
Age can also affect a dog’s hearing. As dogs age, their hearing can deteriorate, just like in humans. This means that an older dog may not be able to hear as far away as a younger dog.
How Can You Test a Dog’s Hearing?
If you suspect your dog may have a hearing problem, there are a few tests you can do to check. The most common test is a brainstem auditory evoked response (BAER) test. This test measures the brain’s response to sound and can detect even mild hearing loss.
You can also do a simple test at home. Make a loud noise and observe your dog’s reaction. If your dog does not respond, then it may be a sign of hearing loss.

## Common Myths About How Far Dogs Can Hear
1. Myth: Dogs can hear sounds that humans cannot.
Fact: Dogs can hear higher pitched sounds than humans, but cannot hear sounds outside of the human hearing range.
2. Myth: Dogs hear better than humans.
Fact: Dogs have better hearing than humans in some areas, but humans are more sensitive to subtle changes in sound.
3. Myth: Dogs can hear a greater range of frequencies than humans.
Fact: Dogs can hear higher-pitched sounds than humans, but the range of frequencies they can hear is comparable to that of humans.
4. Myth: Dogs can hear sound waves better than humans.
Fact: Dogs may be better at detecting sound waves, but humans can filter out background noise better than dogs can.
Frequently Asked Questions
How far away can a dog hear sound?
Answer: A dog’s hearing range can be up to four times greater than a human’s. Depending on the breed, a dog can typically hear sound up to a distance of around 20-40 kilometers away.
Can a dog hear frequencies outside of the human hearing range?
Answer: Yes, dogs can hear frequencies that are outside of the range of human hearing. A dog’s hearing range extends from 40 Hertz (Hz) to 60,000 Hz while the human hearing range is between 20 Hz and 20,000 Hz.
