Sound is a type of energy made by vibrations . 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.
How is sound produced very short?
Sound is produced when an object vibrates, creating a pressure wave . ... As the particles vibrate, they move nearby particles, transmitting the sound further through the medium. The human ear detects sound waves when vibrating air particles vibrate small parts within the ear.

How is sound produced answer in one word?
Sound is produced when something vibrates . The vibrating body causes the meadium(water,air etc) around it to vibrate. Sound waves consist of high and low pressure called compression and rarefactions , respectively .
How was sound made?
Sounds are made when objects vibrate . The vibration makes the air around the object vibrate and the air vibrations enter your ear. ... You cannot always see the vibrations, but if something is making a sound, some part of it is always vibrating.
Where is sound produced in humans?

How is sound produced Grade 8?
Answer: Sound is produced when something vibrates . The vibrating body causes the medium (water, air, etc.) around it to vibrate. Vibrations in the air are called travelling longitudinal waves, which we can hear.
What is study of sound called?
acoustics , the science concerned with the production, control, transmission, reception, and effects of sound. ... Beginning with its origins in the study of mechanical vibrations and the radiation of these vibrations through mechanical waves
What is sound class 9th?
Sound is a mechanical energy which produces sensation of hearing . Sound is produced due to vibration of different objects. • Sound wave propagates as compressions & rarefactions in the medium. Sound waves are longitudinal waves.
What is sound in simple words?
Sound is caused by sound waves . It can be heard when goes through a medium to the ear. All sounds are made by vibrations of molecules. For example, when a person hits a drum or a cymbal the object vibrates. ... These vibrations let you hear different things.
Who made sound?
Who Invented Sound Recording? Thomas Edison was catapulted to international fame with his 1877 invention of the phonograph—a machine that recorded and played back anything that it “heard.” But Edison was not the first person to record sound.
What are 3 ways you can make sound?
- By vibrating membranes.
- by vibrating strings.
- by vibrating plates.
- by vibrating air columns.
What are the 4 properties of sound?
Since sound is a wave, it has all of the properties attributed to any wave, and these attributes are the four elements that define any and all sounds. They are the frequency, amplitude, wave form and duration , or in musical terms, pitch, dynamic, timbre (tone color), and duration.
How is sound produced in humans explain?
Human sound is produced by the larynx . ... Air from lungs passes current between two vocal cords. The air inside two vocal cords makes the cord vibrate and this vibration produces sound.
How do humans talk?
To speak, you use your stomach muscles, lungs, voice box, tongue, teeth, lips, and even your nose . ... This is a large muscle that helps push air from the lungs into the voice box. The voice box or larynx has vocal cords that vibrate to produce your voice. Then, the lips, tongue, and teeth form the sounds to make speech.
How sound is produced in humans with diagram?
The vocal folds (vocal cords) are attached within the larynx to the largest of the laryngeal cartilages known as the thyroid cartilage or “Adam's apple”. The vocal folds produce sound when they come together and then vibrate as air passes through them during exhalation of air from the lungs.
