What frequency range can a cat hear? - briefly
Cats can hear frequencies ranging from approximately 48 Hz to 85 kHz, significantly surpassing the human auditory range.
What frequency range can a cat hear? - in detail
Cats possess an exceptional auditory system that allows them to detect a wide range of frequencies, far surpassing the capabilities of humans. While humans typically hear sounds within the range of 20 Hz to 20,000 Hz, cats can perceive frequencies from approximately 48 Hz up to 85,000 Hz. This extended upper range enables them to hear ultrasonic sounds, which are inaudible to humans. The ability to detect such high frequencies is particularly advantageous for hunting, as many small prey animals, like rodents and insects, produce ultrasonic vocalizations and movements. The structure of a cat’s ear, including its highly mobile outer ears (pinnae), amplifies and directs sound waves into the ear canal, enhancing their sensitivity to high-frequency sounds. Additionally, cats have a specialized organ called the cochlea in their inner ear, which is finely tuned to process these frequencies with remarkable precision. This acute hearing ability is not only essential for survival in the wild but also contributes to their heightened awareness and responsiveness to their environment. However, as cats age, their hearing range may diminish, particularly in the higher frequencies, similar to the hearing loss experienced by humans over time. Overall, the feline auditory system is a remarkable adaptation that underscores their evolutionary success as predators and their unique sensory capabilities.
