With ears
The sounds animals can hear is based on the frequency that the certain animal can hear. For example, dog's can hear at much higher frequencies then humans can, so if a sound is made that is above our capability of hearing, we will not hear the sound, but the dog will.
The shape of an animal's ears can help determine how well it can hear. Large ears tend to collect and funnel more sound waves to the ear canal, improving hearing sensitivity. The distinctive shapes of some animals' ears can also help them detect the direction of a sound more accurately.
All animals have different sensitivities of hearing. Different animals hear different sounds. Like a dog. A dog has one of the most sensitive hearing levels. That's what dog whistles were meant to do. They were supposed to make it so humans can't hear it but dogs can.
Because each animal has a different range of sensitivity for sound frequencies; also not all the human beings are identical.
A cat will make a hissing sound when it feels that it is in any form of danger. This sound is made to warn other animals or people off.
where people or animals hear from
No, animals do not hear the same frequencies of sound as humans. Different animals have different ranges of hearing, with some able to hear higher or lower frequencies than humans.
The sounds animals can hear is based on the frequency that the certain animal can hear. For example, dog's can hear at much higher frequencies then humans can, so if a sound is made that is above our capability of hearing, we will not hear the sound, but the dog will.
Some animals, like snakes and fish, do not have ears and cannot hear sound in the same way that humans and other animals can.
No, they don't. Animals communicate and hear differently. Some don't even hear at all
bats can hear ultrasonic sound
Cats, dogs, rabbits...
To know if a predator is coming
Animals that can hear infrasonic sounds are; frogs snakes ants dogs fishes whales beetles pigeons Usally, small animals can hear infrasonic sounds because they catches low frequency sound which is less than 20 Hz, especially insects. You may have observed that even if you walk very softly on the floor, animals like dogs feels your coming because they can hear infrasonic sounds.
sound can be produced in any medium - air, water and solids too, but most of the sounds we hear are through air. Animals like dolphins produce sound in water and hear it there.
Some animals can hear higher frequencies than humans can. This is why animals can hear things like dog whistles, and we can't hear them. In all, animals can hear differently than humans in the way that they can hear more. Some animals can hear lower frequencies than humans can. Elephants can hear much lower frequencies than humans.
They hear the sound of animals such as sheep and go hunting them down so they can get food.
