Meow Mumbling. What Cats Hear When Humans Talk

What’s So Special About A Cat’s Ears?

When you talk to your cat, their ears may perk up, swivel, and twitch as they take in every sound. While it may seem like they ignore our chatter, their exceptional hearing allows cats to detect sounds and decipher meaning from voice cues that humans can’t perceive. A cat’s ears are finely tuned instruments, evolved for hunting and survival. But how do they interpret our voices, and what exactly do cats hear when we talk to them?

Anatomy of a Cat’s Ear

A cat’s external ear consists of the pinna, ear canal, and eardrum. The pinna is the large, prominent flap that collects and funnels sound into the ear canal. The pinna can rotate nearly 180 degrees to precisely pinpoint the source of a sound (1). The ear canal leads to the eardrum and is lined with fine hairs and wax that prevent foreign matter from entering (2).

The middle ear contains the three smallest bones in a cat’s body – the malleus, incus and stapes. These bones amplify the vibrations coming from the eardrum. The middle ear is connected to the back of the throat by the Eustachian tube, which equalizes pressure in the ear (1).

The inner ear contains the cochlea and vestibule, which are responsible for hearing and balance. The cochlea is a fluid-filled, spiral-shaped cavity lined with sensitive hair cells that transform sound waves into nerve impulses. The vestibule contains three semi-circular canals that detect head position and movement (2).



Hearing Range

Cats have an exceptionally broad hearing range that exceeds both human hearing and the hearing range of dogs. According to a 1985 study published in the journal Brain, Behavior and Evolution, the hearing range for domestic cats with sounds of 70 dB SPL extends from 48 Hz to 85 kHz. This gives cats one of the widest hearing ranges among mammals.

In comparison, the average human hearing range is commonly cited as 20 Hz to 20 kHz. However, human hearing declines with age, and most adults over 50 only have a functional hearing range up to 12-15 kHz. Dogs can generally hear sounds up to 47 kHz, giving cats a significantly broader upper range.

The wide hearing range allows cats to detect high-frequency sounds made by their prey that humans simply cannot hear. Their hearing is well adapted to their hunting behavior and environment.

Hearing Sensitivity

Cats can hear sounds at much lower volumes than humans. Their hearing sensitivity allows them to detect sounds as low as -5 decibels, whereas humans can only hear down to about +10 decibels (Source). This means cats can hear sounds that are barely audible to us.

There are a few reasons for cats’ sensitive hearing. First, their large, movable outer ears help funnel sound into their ears. Second, cats have a wide range of hearing – from 45 Hz up to 64 kHz – allowing them to detect a broader spectrum of sounds. Finally, their inner ear anatomy includes a larger basilar membrane that is more sensitive to vibration (Source). This anatomical advantage allows cats to pick up fainter noises.


Cats have excellent sound localization abilities, allowing them to accurately pinpoint the source of a sound using their ears. According to studies, cats can localize sound within about 13 degrees in the central field of vision and 21 degrees in the periphery (Heffner, 20051). This is slightly worse than humans, who can localize sounds within about 2-3 degrees, but is superior to most other mammals.

A cat’s precise sound localization is vital for hunting. It allows cats to accurately track and pounce on prey, even in low light conditions when visual cues are limited. Studies have shown cats can detect prey rustling in vegetation from over 10 feet away using sound localization alone (Heffner & Heffner, 20052). Their mobile pinnae (outer ears) and sensitive inner ear anatomy give cats an evolutionary advantage for localizing sounds in 3D space compared to prey species like rodents.

Overall, cats’ excellent ability to pinpoint sound sources using only their ears allows them to be effective hunters and likely contributed to their success as a species.

Vocal Recognition

Cats can recognize their owner’s voice and distinguish it from other people’s voices. This ability comes from the fact that cats form strong bonds with their owners and become attuned to their voice specifically. When a cat hears its owner speaking, it recognizes the unique tone, pitch, and timber of their voice.

Studies have shown that cats react differently when they hear their owner versus a stranger. For example, they are more likely to come when called by their owner, indicating they can pick out their name and are more attentive to their owner’s voice. Cats also recognize words and phrases frequently used by their owners, such as “treat” or their name. Their ears may perk up when hearing these familiar words.

Cats are able to identify their owners by voice because voices have distinctive acoustic features. No two people have the exact same vocal frequencies and patterns. Cats recognize the unique rhythm, emphasis, and inflection in their owner’s voice after repeated exposure over time. Their advanced sense of hearing allows them to pick up on these nuanced details. So when a cat hears its owner speak, it recognizes the familiar voice and responds accordingly.

Tone Interpretation

It’s well known that cats respond to the tone of an owner’s voice. According to research from, cats can detect when their owners are directing speech towards them. Cats pay attention to the tone, pitch, and cadence of human voices.

Cats seem to respond more strongly to high-pitched voices. A higher tone tends to get a cat’s attention, while a lower tone can be calming. When humans use an affectionate, soothing voice with cats, it likely signals safety and caretaking to the cat. Cats learn to associate soothing voices with being petted or fed. On the other hand, loud or harsh tones often indicate displeasure to a cat.

Language Comprehension

Cats have a limited ability to comprehend human language. Though they cannot understand grammar and syntax, cats can learn to recognize certain words and short phrases that get frequently repeated to them (cite1). For example, cats may learn that words like “treat”, “food”, or their name means they are about to be fed. They also pick up on common phrases like “up,” “come here,” or “want to go outside?” by associating them with consistent outcomes. However, cats do not actually understand the meaning behind most human words and sentences. The extent of language comprehension in cats mainly comes down to being able to identify words they hear frequently that are relevant to their daily routines and experiences (cite 1)

It’s important not to overestimate cats’ language abilities. While they can recognize certain words and phrases, most of what we say sounds like meaningless noise to them. Expecting cats to understand complex instructions or abstract concepts can lead to frustration for both humans and cats. Instead of focusing on teaching vocabulary, it is more constructive to establish clear routines, use consistent cues like gestures and tones of voice, and create positive associations between verbal commands and meaningful actions (cite 2). This allows for better human-cat communication and understanding of each other’s intent. Though cats have limited language skills compared to humans, we can find meaningful ways to connect through patience, routine, and shared experience.

Meowing Back

Cats primarily meow at humans as a means of communication. Unlike meows exchanged between cats, which convey things like discomfort or distress, meows directed at humans often serve social purposes. According to research, cats developed meowing specifically to communicate with people.

There are several reasons cats meow at their human companions:

  • Attention seeking – Cats may meow when they want food, playtime, or affection from their owner.
  • Greeting – Some cats will meow happily when their owner comes home.
  • Boredom – Meowing can signal a cat wants stimulation and activity.
  • Distress – An anxious or scared cat may meow repeatedly.

Cats use different meow tones and pitches to convey different meanings. With experience, cat owners can learn to distinguish various meows. For example, a plaintive, drawn-out meow may indicate hunger whereas a short, repetitive meow can mean impatience. Understanding a cat’s unique vocalizations leads to better human-feline communication.


In summary, we’ve learned several fascinating facts about cats’ hearing abilities. Cats have a wide hearing range, with the ability to detect sounds between 45 Hz to 64 kHz. Their ears contain specialized anatomical structures like the pinnae and the ossicles that allow cats to hear faint sounds and localize their source with precision. While cats can recognize and respond to specific tones in our voices, they cannot comprehend human language in the same way that we do. However, they are very adept at understanding our emotional state through vocal cues. Their meowing back to us is a social communication behavior, not an attempt at conversation. One amazing final note – cats can hear sounds so faint that they miss our range of hearing altogether! Their acute sensitivity allows cats to detect noises we can’t even perceive.
