Cats are highly skilled predators with excellent agility and reflexes. They are able to catch prey such as rodents and birds by stalking and pouncing on them. Cats have a sharp sense of hearing which is more sensitive than that of humans. They can hear frequencies up to 64,000 Hz, compared to humans who can hear up to 20,000 Hz. This helps them detect and locate prey, as well as communicate with other cats through vocalizations.
Do You Hear What I Hear was written in October 1962 as a plea for peace amid the Cuban Missile Crisis. Please see the related link for more information:

Humans cannot consciously hear infrasound, as it falls below the threshold of normal hearing (below 20 Hz). However, there is some evidence that infrasound can be perceived as a feeling of unease or fear, as it may cause vibrations within the body.
Humans can't hear sounds that are below 20Hz (infrasound) or above 20,000Hz (ultrasound). Infrasound is produced by natural phenomena like earthquakes and by some animals, while ultrasound is used in medical imaging and by animals like bats for echolocation.
Humans use infrasound for various purposes such as detecting earthquakes, monitoring volcanic activity, and studying wildlife behavior. Infrasound is also utilized in communication systems and for medical imaging. Some studies suggest that exposure to certain infrasound frequencies may have physiological effects on humans.
Infrasound refers to sound waves with a frequency lower than what humans can hear, typically below 20 Hz. These frequencies are often produced by natural events like earthquakes or man-made sources like industrial machinery. Although we can't hear infrasound, it can still affect us physiologically and emotionally.
"Sound" is a mechanical wave traveling through a medium. Ultrasound is sound, but its frequency is higher than humans can hear.
No, humans cannot hear the sounds made by elephants under normal circumstances. Elephants produce low-frequency infrasound vocalizations that are below the range of human hearing. However, elephants can communicate with each other over long distances using these infrasound frequencies.
Sonic infrasound is a sound too low for humans to hear, below 20 Hertz. Ultrasound is a sound too high for humans to hear, above 20,000 Hertz.
infrasound
Sound waves that are too low to hear are referred to as infrasound. These waves have frequencies below the threshold of human hearing, typically below 20 Hz. Even though we cannot hear them, infrasound waves can still have effects on humans and animals.
Infrasound refers to sound waves with frequencies below the lower limit of human hearing, typically below 20 Hz. Infrasound can be produced by natural sources like earthquakes or man-made sources like industrial machinery. Although humans cannot hear infrasound, they can still feel its effects, such as uneasiness or discomfort.
Humans can hear with in a range of 20 Hz - 20,000 Hz. Below 20 Hz is infrasound, and above 20,000 Hz (20 kHz) is ultrasound.
Animals such as dogs, cats, and certain insects can hear ultrasound frequencies that are beyond the range of human hearing. Whales and dolphins can also detect sounds in the infrasound range, which are lower than what humans can perceive.
