What are some things that vibrate to produce sound?
Everyday Examples of Sound Energy
- an air conditioning fan.
- an airplane taking off.
- a ballerina dancing in toe shoes.
- a balloon popping.
- the bell dinging on a microwave.
- a boombox blaring.
- a broom swishing.
- a buzzing bee.
How is vibration produce?
When an object vibrates, it causes movement in surrounding air molecules. These molecules bump into the molecules close to them, causing them to vibrate as well. This makes them bump into more nearby air molecules. This “chain reaction” movement, called sound waves, keeps going until the molecules run out of energy.
Can you clap underwater?
The clapping is a powerful underwater noise. It is a high frequency sound that cuts through any background noise. As it turns out, underwater clapping is not audible above the surface of the water, but is quite loud below the surface.
Why can you not hear in space?
No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.
What animal can see sounds?
Bats and Dolphins See With Sound By analyzing the time and volume of sound as it echoes back to each ear, and the difference from one ear to the other, these animals can create a three-dimensional mental representation of their surroundings.
What kind of sound does a vibration make?
This energy then moves through the air as a pressure wave. If the vibration is strong and slow, like a bass drum hit with a soft mallet, the sound will be loud and low in pitch, if the vibration is weak but fast, like a pin falling on a wooden floor, the sound will be soft and high pitched.
How does a loudspeaker cause your ear to vibrate?
The vibrations that cause us such great concern, are those that comprise the very nature of our hobby – sound. Our loudspeakers produce sound by the motion of their drivers, creating compressions and rarefactions of air molecules within the room. The eardrum vibrates in sympathy with these modulations of the air.
Can a computer make sound without a vibration?
You cannot have audible sound without vibration, even where a computer simply creates sound from a passing detected gravitational wave. The sound produced by a vibrating pendulum is not heard. Why? Source.
Where do you get the vibrations from when you speak?
When blowing through their “fart whistles,” students get to both see and feel the vibrations of the sound. When you speak, you use the muscles in your tongue, lips, jaw, and pharynx to make the vocal cord vibrations into words.
