Does a falling tree make a sound if no one is there to hear it?
The falling of the tree or any other disturbance will produce vibration of the air. If there be no ears to hear, there will be no sound.”
Who said if a tree falls in a forest and no one is around to hear it does it make a sound?
George Berkeley
What is the answer to if a tree falls in the forest does it make a sound?
Does it make a noise? The answer is quite simple if answering on a physical level: Yes and No! Yes, it makes a sound, that being a disturbance in the fluidic medium, air. When the tree falls it causes a disturbance in the air pressure field in the woods and that pressure field emanates away from the fallen tree.
Is the energy produced by the vibration a sound if no one hears it?
No it doesn’t. Sound is the product of our ears. If there are no membranes (ears, microphones etc) to vibrate then there is no sound.
Why is sound unable to travel through a room that has no air?
Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. Radio is a form of electromagnetic radiation just like light and can therefore travel through the vacuum of space just fine.
Which animal can feel the vibration of the sound and hear?
By using vibrations, highly social elephants can tell each other about danger from miles away. (See “Elephants Communicate in Sophisticated Sign Language, Researchers Say.”) Mole rats are a group of rodents that live in underground burrows.
Can bats hear human voices?
Not All Bats Echolocate Also, bats aren’t the only animals that use echolocation. Some bat sounds humans can hear. The squeaks and squawks that bats make in their roosts or which occur between females and their pups can be detected by human ears, but these noises aren’t considered to be echolocation sounds.
Which animal can hear the lowest frequencies?
Elephants have some of the best hearing around. They can hear at frequencies 20 times lower than humans.
What frequencies should I hear at my age?
People of All ages without a hearing impairment should be able to hear the 8000hz. People under 50 should be able to hear the 12,000hz and people under 40, the 15,000hz. Under 30s should hear the 16,000hz, and the 17,000hz is receivable for those under 24. MORE: Test!
Do cats hear better than dogs?
As far as our pets hearing is concerned, both dogs and cats hear better than us, especially in the upper ranges. In fact, cats can hear almost one octave higher than dogs, and both can hear in the ultrasound level.
Can a cat smell a dog?
While cats have far fewer scent receptors than dogs, recent research has shown that cats may be better at discerning between different smells. Finally, cats use their whiskers to enhance their senses of touch and balance.
What do cats hear when we talk to them?
Japanese researchers have found that cats can distinguish their owners’ voices from those of other people – implying that they do pay attention when spoken to. The researchers found that cats responded to voices by moving their heads and/or ears nearer the person who was speaking to them.
How far away can a cat hear you?
Indeed, a healthy cat can even judge within three inches the location of a sound being made three feet away, which assists in the locating of prey. They can also “hear sounds at great distances – four or five times farther away than humans.”
Can a cat understand human meows?
Let us be honest; cats cannot understand human meows. But other than that, to them, it just sounds like the normal human language. This is because humans cannot make the exact meow that cats make, therefore each meow sounds different. Meowing at cats allows one to mock them but on a level that they can appreciate.
Should I meow back at my cat?
Your cat meowing back at you doesn’t mean that she’s acknowledging your communication and continuing the conversation – it means that she wants something! Having said that, meowing at a cat certainly won’t cause any harm.
What do cats see us as?
Cats treat us as though they think we are giant, clumsy fellow cats. Cat behavior researcher John Bradshaw of the University of Bristol says that cats probably see us as especially clumsy — which most of us are, by cat standards. However, despite legions of Internet memes, they do not see us as foolish inferiors.
Why do cats hide away to die?
Do cats know they are dying? According to Desmond Morris in his book Cat World – A Feline Encyclopedia, cats have an advantage over humans in regards to death, they don’t know what death is. They go away and hide because they are sick and feeling vulnerable. This makes perfect sense from an evolutionary point of view.
Will a cat eat a dead human body?
The body farm discovery sent Dr. Delgado down a rabbit hole of research into the phenomenon of cats eating dead bodies, which she documented on her blog. “And the other thing that’s important to recognize is that just because animals will eat part of a corpse does not mean that they will eat you when you’re alive.”
Do cats know their name?
Cats Recognize Their Own Names—Even If They Choose to Ignore Them. Cats are notorious for their indifference to humans: almost any owner will testify to how readily these animals ignore us when we call them. But a new study indicates domestic cats do recognize their own names—even if they walk away when they hear them.
