Cats have excellent hearing and can detect a very broad range of frequencies. They can hear higher-pitched sounds than humans or most dogs, with frequencies ranging from 55 Hz to 79 kHz. This ability to hear ultrasound is likely important in hunting, as many rodents make ultrasonic calls. Cats' hearing is also highly sensitive, especially in the range of 500 Hz to 32 kHz, and their large movable outer ears further enhance this sensitivity. Interestingly, ultrasonic deterrents have been shown to reduce nuisance cat activity in suburban areas, indicating that cats do respond to ultrasonic sounds.

What You'll Learn
Cats can hear ultrasonic sounds
Cats have a remarkable sense of hearing and can detect a very wide range of frequencies. They can hear higher-pitched sounds than humans or most dogs, with frequencies ranging from 55 Hz to 79 kHz. This ability to hear ultrasound is likely crucial when hunting, as many rodent species communicate using ultrasonic calls.
The sensitivity of a cat's hearing is enhanced by their large, movable outer ears, which amplify sounds and help them pinpoint the source of a noise. This is particularly useful for hunting small prey, such as mice, whose vocalizations are within the cat's hearing range.
While cats can hear ultrasonic sounds, they do not use this ability for communication. Instead, it is a tool that aids them in hunting and likely developed as an adaptation to help locate and capture prey.
Ultrasonic deterrents have been shown to reduce unwanted cat activity in suburban areas. These devices emit sounds that cats can detect and respond negatively to, reducing the frequency and duration of their incursions. This provides a humane way to address issues caused by roaming cats without causing them harm.

Cats use ultrasonic hearing for hunting
Cats have an extremely broad hearing range, being able to detect frequencies from 55 Hz up to 79 kHz. This upper limit is far into the ultrasonic range. For comparison, humans can hear up to 17.6 kHz, while dogs can hear higher frequencies than us but still lower than cats, at around 40-60 kHz.
Cats' ultrasonic hearing is likely important for hunting, as many species of rodents, such as mice and rats, make ultrasonic calls. Mice can squeak at frequencies that are inaudible to humans, but these are well within the hearing range of cats. This allows cats to locate their prey even when they cannot see it.
Cats' hearing is also extremely sensitive, especially in the range of 500 Hz to 32 kHz. This sensitivity is enhanced by their large, movable outer ears, which amplify sounds and help them to sense the direction from which a noise is coming.
While cats can hear ultrasounds, they do not use this ability for communication. Instead, they rely on their ultrasonic hearing for hunting and locating prey.
In summary, cats possess exceptional ultrasonic hearing that far surpasses that of humans and most other mammals. This ability is crucial for their hunting prowess, enabling them to detect and locate prey that produce ultrasonic calls, such as rodents.

Ultrasonic sounds can be used to deter cats
Cats have excellent hearing and can detect a very broad range of frequencies. They can hear higher-pitched sounds than humans or most dogs, with frequencies ranging from 55 Hz to 79 kHz. This ability to hear ultrasound is likely important for hunting, as many rodent prey make ultrasonic calls. Cat hearing is also extremely sensitive, particularly in the range of 500 Hz to 32 kHz, and is enhanced by their large, movable outer ears, which amplify sounds and help them pinpoint the source.
Due to their ultrasonic hearing capabilities, cats can be deterred by ultrasonic sounds. Ultrasonic deterrents have been shown to reduce the frequency and duration of cat incursions into unwanted areas, such as gardens and parks. In a study conducted in Perth, Australia, ultrasonic cat deterrents were tested in 18 suburban gardens. The results showed that overall, ultrasonic deterrents reduced the frequency of incursions by resident cats by 46%, and the duration of incursions by 78%.
Ultrasonic deterrents provide a cost-effective and humane way to reduce the nuisance behavior of cats in urban environments, such as hunting, fighting, and urine spraying. These devices do not cause any hearing damage to cats but rather emit sounds that cats find unpleasant, encouraging them to leave the area.
While ultrasonic deterrents are effective for resident cats, it is worth noting that they may be less successful in deterring peripheral cats, or cats that are not regular visitors to the area. Additionally, ultrasonic deterrents may not prevent all incursions, but they can significantly reduce their occurrence and the length of time cats spend in the area.

Cats have a broader hearing range than humans
This ability to hear ultrasonic sounds is likely an important adaptation for hunting, as many species of rodents, such as mice, make ultrasonic calls. Cats' hearing is also extremely sensitive, especially in the range of 500 Hz to 32 kHz. Their large, movable outer ears amplify sounds and help them pinpoint the direction from which a sound is coming.
Ultrasonic sounds are used to deter cats from certain areas in a humane way. Studies have shown that ultrasonic devices can reduce the frequency of cat incursions into gardens by 46% and the duration of incursions by 78%.
While cats have a broader hearing range than humans, there are other animals that can hear even higher frequencies. For example, bats have evolved very sensitive hearing to navigate their nocturnal environments, with some species capable of hearing frequencies up to 200 kHz. Similarly, birds like pigeons can hear infrasound, with the average pigeon able to detect sounds as low as 0.5 Hz.

Cats have more acute hearing than most dogs
The superior hearing range of cats compared to dogs is evident when examining the frequencies they can perceive. Cats can detect sounds starting from 55 Hz, while dogs' hearing range typically begins at higher frequencies. Additionally, cats can perceive ultrasonic sounds, with their upper limit reaching 79 kHz. In contrast, dogs' hearing range extends into the ultrasonic spectrum, but their upper limit is generally lower than that of cats.
The advantage of cats' hearing abilities becomes apparent when considering their hunting prowess. Many rodent species, including mice, communicate through ultrasonic calls. Cats' ability to hear these ultrasonic frequencies allows them to locate their prey effectively. Mice, on the other hand, have evolved to produce sounds outside the hearing range of predators like dogs, using higher-frequency vocalizations for close-range communication.
The design of cats' ears also contributes to their exceptional hearing. Their large, movable outer ears, known as pinnae, play a crucial role in enhancing their auditory capabilities. These external ears not only amplify incoming sounds but also assist cats in accurately pinpointing the direction from which a sound originates. This directional hearing provides cats with a distinct advantage when hunting or navigating their surroundings.
While cats possess superior hearing abilities compared to most dogs, it is worth noting that dogs also have impressive auditory capabilities. Dogs' hearing is more sensitive than humans', and they can perceive higher-frequency sounds. Dog whistles, which emit ultrasonic frequencies, are commonly used in dog training, as dogs respond better to these higher-frequency signals.
In summary, cats indeed have more acute hearing than most dogs, with a broader frequency range extending into the ultrasonic spectrum. Their sensitive hearing, coupled with their movable outer ears, enhances their hunting abilities and overall perception of their environment. However, it's important to recognize that dogs also possess specialized hearing capabilities that serve them in unique ways.
