What makes a sound loud or soft?
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.
What things produce soft noise?
Banging of a hammer and a car’s horn are examples of loud sounds while playing of a piano and sound of blowing wind are examples of soft sounds.
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.
What is a soft a sound?
A soft sound is a long sound made with a continuing breath, as in: Jeep, shine, check, zebra.

How does a spoon make 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. When we attach the strings to this and tap them straight into your ears, the sound waves travel directly along the string and are brought directly into your ears.
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 are examples of loud sounds?

Which of the following produces the loudest sound?
The Krakatoa volcanic eruption: Not only did it cause serious damage to the island, the eruption of Krakatoa in 1883 created the loudest sound ever reported at 180 dB. It was so loud it was heard 3,000 miles (5,000 km) away. 3. A 1-Ton TNT Bomb: An explosion from this bomb would measure 210 dB.
What are the loudest sounds?
Here are some of the most ear-shattering sounds ever recorded.
- Krakatoa eruption of 1883 (310dB)
- Tsar Bomba (224dB)
- Saturn V Rocket (204dB)
- Chelyabinsk meteor (180dB)
- Howler monkeys (140dB)
- Republic XF-84H ‘Thunderscreech’ (est 200dB)
- Large European Acoustic Facility (LEAF) (154dB)
Can you tell what object is dropped by its sound?
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 do things sound similar when they hit 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.
What is the difference between pitch and loudness?
At a loudness of above 80 Db ,the sound become physically painful. And at about 140 Db level ,sound hurts too much. Pitch is that characteristic of sound by which we can distinguish between different sounds of the same loudness. We can distinguish between a man’s voice and a woman voice even without seeing them.
Why do we hear different sounds from different materials?
Because materials vibrate in many ways and our ears are designed to register tiny differences, we hear a variety of sounds. A metal object crashing onto a hard floor will vibrate in a specific way creating a specific sound. Other metal objects will vibrate in a similar—but not identical—way creating a similar sound.
