How Well Can Cats Hear? Their Hearing Range
12 June 2024 • Updated 10 June 2024
Cats have the ability to hear a wide range of sounds from a great distance, but how far can they really hear? Cats can hear sounds from up to three-quarters of a mile away, which is much further than humans, who can hear sounds from a maximum distance of about 600 feet. This is due to the specialized anatomy of cats' ears and the number of muscles in their ears compared to humans.
To truly understand how amazing cats' hearing is, we will look at a number of scientific studies from fields such as animal anatomy, biology, and ethology. We will not only look at the physical characteristics that allow cats to hear so well but also how their hearing impacts their predatory instincts and how they perceive the world around them. Let's dive into the world of sound from a cat's perspective.
How well can cats hear?
The Anatomy of a Cat's Incredible Hearing
A cat's incredible hearing is due to several factors, including the animal's specialized ear anatomy. Cats have large, cone-shaped external ears that can amplify sound waves up to two or three times for frequencies between 2,000 and 6,000 Hertz. This amplification is made possible by the external ears, or pinnae, which are equipped with about 30 sets of muscles that enable the ears to rotate up to 180 degrees, allowing cats to zero in on even the quietest sounds.
Cats also have longer, more angled ear canals than humans. While human ear canals are only 2.5 cm long, cats' ear canals are longer and take a 90-degree turn. This enables them to hear a wider range of high-pitched sounds that are inaudible to humans and dogs.
Inside the ear, cats have a larger cochlea and unique middle ear bone structure that further enhance their ability to hear. The cat's external ears and their ability to move in conjunction with the pinnae not only amplify sounds but also enable cats to pinpoint their source with great accuracy, which is essential for hunting and avoiding predators.
Despite these advantages, cats can experience hearing problems. Some cats are born deaf, and white cats with blue eyes have an 80% chance of being born deaf if they're not deaf by the time they're 4 days old. Cats can also experience hearing loss as they age or due to infections or exposure to ototoxic substances, which can make it harder for them to survive.
How Cats Use Their Hearing: Hunting and Survival
Cats' super-sensitive hearing is especially important for their survival in the wild because it helps them track and hunt prey. Per Tails & Tips, cats can hear the smallest sounds their prey makes from a distance, which helps them find and catch their prey. They can also tell what kind of animal is making the sound and how big it is, which helps them decide whether it's worth hunting.
This ability to locate sounds also helps cats hunt in the dark when their vision is limited. Per Psychology Today, cats' sensitive hearing also helps them avoid predators by hearing them coming and getting away in time. These super-sensitive senses help cats become highly effective hunters, even in a home environment.
Vocalization: Understanding the Hearing Range of Cats
Cats use a variety of vocalizations to communicate, including murmuring sounds like purring and trills, miaowing or vowel sounds, and aggressive sounds like growls and hisses. International Cat Care explains that these vocalizations have evolved to fulfill a number of different functions, including agonistic interactions, sexual interactions, mother-kitten interactions, and cat-human interactions.
Cats' sensitive hearing allows them to hear and understand these vocalizations, which are essential for communication within their social groups. Fear Free Happy Homes explains that cats can hear a range of pitches over 10.5 octaves, which is one of the widest ranges of any mammal, enabling them to understand the subtleties of feline vocalizations.
Ear movements and positions also play a role in communicating a cat's emotions and mood, offering important nonverbal signals. Hill's Pet says that a cat's ears can rotate up to 180 degrees to help them locate sounds, and their position can indicate everything from relaxation to aggression. Knowing how to interpret a cat's vocalizations and ear language can help cat owners better understand their pet's behavior and needs.
Age and Health: How Your Cat's Hearing Changes
Just like humans, cats can experience age-related hearing loss. This is due to the eardrums losing flexibility. VCA Animal Hospitals explains that this type of hearing loss happens slowly and can be hard to detect at first because the eardrums lose flexibility and can't transmit sound as well.
In addition to age-related hearing loss, cats can also experience hearing loss due to chronic ear infections, tumors, or obstructions, or they can be born with it (congenital deafness). Vetwest Veterinary Clinics explains that white cats with blue eyes are especially prone to congenital deafness, and about 80% of these cats will show signs of deafness by the time they're 4 days old.
Some signs that your cat may be losing their hearing include meowing more loudly, not responding when you call their name, being easily startled, and sleeping more. WagWalking recommends taking your cat to the vet regularly and watching for changes in their behavior to catch hearing loss early and ensure that it's properly managed.
Knowing the different causes and signs of hearing loss in cats is important for making sure that our feline friends are as healthy and happy as possible as they get older. With the right medical care and home adjustments, cats with hearing loss can still live full lives.
How Cat Hearing Compares to Other Animals and Humans
Cats’ hearing range covers approximately 10.5 octaves, which is significantly more than the 9.3 octaves humans can hear. Cats are most sensitive to middle frequencies, which means they can hear sounds that are much quieter than those that humans can hear.
Compared to dogs, cats can hear higher frequencies and hear sounds from a greater distance, which helps them when hunting small animals. However, while cats have more sensitive hearing than dogs, other animals like bats and dolphins have even more specialized hearing that helps them with their hunting and survival.
By learning how cats’ hearing compares to other animals and humans, we can learn more about their unique sensory abilities and behaviors, which in turn can help us better understand and enjoy the unique world of cat hearing.
Conclusion: Understanding the Feline Auditory Experience
Cats have an amazing sense of hearing that is much more acute than humans, enabling them to hear and locate sounds from much farther away. The unique anatomy of their ears and their wide range of frequencies are adaptations that help them hunt and survive, especially when it comes to finding small prey. Feline vocalizations and ear movements are important for cats to communicate and interact with other cats and even their human family members.
While a cat's hearing can be affected by age and some medical conditions, regular veterinary care and monitoring can help ensure that any issues are addressed and managed. Understanding and appreciating a cat's unique auditory experience can help you connect with these amazing animals even more.
