What sound does a spoon make?
As the spoon or hanger is hanging in front of you, knock it into the edge of a table to produce a “gong” sound. Explanation: The spoon, when it hits a surface, begins to vibrate. That’s what causes the air to vibrate and produce “sound” in our ears.
What makes sounds soft or loud?
Volume is how loud or soft a sound is. The volume depends on the amount of energy in a sound wave. If you hit a table hard it will make a louder sound then if you hit is soft. A human can hear 120 decibels but it is very painful.

How will you produce sounds in spoon and fork?
When the volunteer hits the spoon, the spoon vibrates. These vibrations travel up the string and into your ear. The vibrations make your eardrums vibrate. This is why the sound of a spoon hitting a fork sounds different with the string near your ears.
Where was the sound heard louder?

How does an object produce sound?
Sound is produced when an object vibrates, creating a pressure wave. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium.
What makes a sound when you drop something on the floor?
When a hard material crashes onto a hard floor, the sudden impact makes it vibrate and creates a sound with a particular tone. If the same object is dropped again, the crash sounds similar because the object vibrates in a similar way.
Why does a crash sound similar to a drop?
If the same object is dropped again, the crash sounds similar because the object vibrates in a similar way. This might make you wonder if you can tell what object dropped, what it is made of, how heavy it is or its shape just by listening to the sound it makes when you drop it.
Why does a hard object make a noise?
There are many faster vibrations—called overtones—on top of the main vibration, each with their own volume. When a hard material crashes onto a hard floor, the sudden impact makes it vibrate and creates a sound with a particular tone. If the same object is dropped again, the crash sounds similar because the object vibrates in a similar way.
How did you learn to distinguish the sounds of falling objects?
You learned to distinguish the sounds of metal, plastic and wooden objects crashing onto a hard floor, which is why you could probably tell what the falling objects were made of. Heavier objects vibrate differently compared with lighter ones.
