Let's compare a human's sensitivity to sound and smell to a dog's:
Humans: hears sounds as high as 20,000 Hz.
Dogs: hears sounds as high as 40,000 Hz
Humans: olfactory up to 10 sq. cm.
Dogs: olfactory up to 150 sq. cm.
They have different structural build-up of their nervous systems. They're able to do different stuff because they weren't created the same way. God made everything unique. Isn't that cool?
They are called infrasonic sounds.
They are called infrasonic sounds.
Dogs and most animals rely on their hearing more than we do. As humans, we rely on eyesight and primates overall have better eyes than other animals.
Humans may use sounds they cannot hear for various reasons such as communication with animals or in technological applications like ultrasound testing. These sounds are either outside the range of human hearing or used for specific purposes where their direct perception is not necessary.
animals make the sounds they do is just like human languages.... for example a whistle may mean they are calling for their family. The animals make the sounds they do because they all need to communicate with each other.
mimicry is when something looks or sounds like something else some birds can mimic human sounds (like parrots) some animals can mimic other animals' sounds
Roughage.
No, finches cannot be taught to mimic human sounds.
Some animals can hear and small things that people cannot because they have more nerves in their nose and ears, a better structure in more or ear for gathering the sound or smells, and devote more of their brain to the sense of smell or hearing than to people.
A large number of animals have chances to eat plastic and other not-to-be-eaten materials.
Both whales and elephants can hear extremely low frequency sounds.
Some sounds that are at certain frequencies cannot be heard by a human ear. Some such sounds are a dog whistle, certain whale songs and dolphin and bat echolocation.
