Sound is a vibration that propagates as a wave. Generally speaking, if you can feel a vibration, you can't hear it - and vice versa. That's because you can only hear vibrations of 20 Hz (20 cycles per second) or more; but you are usually not able to feel anything, if it vibrates that quickly. Of course, most naturally-occurring sounds are a mix of different frequencies, so in some cases you may be able to both hear and feel, especially if the sound is very loud.
What else can I help you with?
Why do you feel vibrations before you hear it?
Vibrations travel faster through a denser medium like a solid than sound waves do in air. This means that you may feel the vibrations before the sound actually reaches your ears.
What we hear as pitch is related mostly to?
To the sound's frequency - how many vibrations per second it has.
Sound waves are waves of vibrating what?
Sound waves are waves of vibrations. When you speak, you vibrate a few air molecules, which vibrate and hit other air molecules, then more and more. when the molecules in your ear vibrate, you hear sound. But really, you feel the vibrations. Then why do we say hear, instead of feel? Because we are already used to saying hear. you wouldn't come to your friend and say, "Speak louder! I can't feel you!"
How does someone hear a sound?
sound waves and vibrations
What is something you cant see touch or feel but you can hear it?
Sound. Sound waves are vibrations that travel through a medium such as air and can be heard by our ears.
How can you hear vibrations?
You can hear vibrations by detecting the movement of air particles caused by sound waves. Your ears capture these vibrations and convert them into electrical signals that your brain interprets as sound.
What three things are needed to hear a sound?
In order to hear a sound, three things are needed: a source of sound producing vibrations, a medium such as air or water for the vibrations to travel through, and the ear to receive and interpret the vibrations as sound.
How do earthworms react to sound?
No, earthworms cannot hear, but the feel the vibrations through the ground. That is their form of sight and hearing.
Can earth worms hear?
No but they can feel vibrations.
Sometimes you feel the vibrations from a sound source before you hear the source itself Why is this?
Sound travels in waves. Our ears register these waves and convert them into noise; however, our ears can only detect a very small range of sound waves. Many sound waves have a frenquency that is much too high or too low for our ears to "hear". If you've ever blown a dog whistle and made your pup yelp in pain while you couldn't hear a thing then you understand. The vibrations that you feel are low frequency sound waves which your body can feel but your ears can't hear. It is only when the higher frequency waves get to you that you hear the source.
Can a cell hear sound?
Sound is nothing but vibrations being traversed in a material medium. These vibrations may be sensed by cells. If you consider this sensation as hearing then we can declare that cells could hear sound.
Can hermit crabs hear?
