Originally Answered: What are the necessary conditions for sound to be produced? You need two, maybe three things – something that's vibrating , a medium for those vibrations to propagate in, and a listener to hear it (or recording equipment to pick it up).
What is the necessary condition for the production of sound 10th class?
Explanation: Sound wave is a mechanical wave that requires a medium for its propagation. For sound to be produced, you will need a vibrating device or object . Anything that can vibrate. ... After that, you will need a medium in which the sound will be propagated.
What is necessary for production and transmission of sound?
For producing the sound waves three things are required, firstly an object that creates vibration by striking it, secondly that body which vibrates on striking and last medium through which sound waves can travel because when an object strikes the vibrating body then vibrations are produced that develops sound waves ...
What are the five sources of sound?
Acoustic instruments, Electrical instruments, Living beings like animals and birds using their vocal cords, Man-made sources like machines, any vibration caused by wind are five sources of sound.
How do we produce sound?
The vocal folds produce sound when they come together and then vibrate as air passes through them during exhalation of air from the lungs. This vibration produces the sound wave for your voice.
What are the three necessary conditions to produce sound?
What are the necessary conditions for sound to be produced? You need two, maybe three things – something that's vibrating, a medium for those vibrations to propagate in, and a listener to hear it (or recording equipment to pick it up) .
Which is used for measuring intensity of sound?
We measure sound intensity (also referred to as sound power or sound pressure) in units called decibels . ... Using the logarithmic decibel scale, if a sound is 80 decibels, and we add another 10 decibels, the sound will be ten times more intense, and will seem about twice as loud to our ears.
What are sound waves produced by?
When you bang a drum its skin vibrates . The harder you bang, the bigger the vibrations. The vibrating drum skin causes nearby air particles to vibrate, which in turn causes other nearby air particles to vibrate. These vibrating particles make up a sound wave.
What are the 3 types of sound?
Sound waves fall into three categories: longitudinal waves, mechanical waves, and pressure waves .
What are the 2 sources of sound?
Name two sources of sound the two sources of sound the first one is vocal cords and peacemaking .
What are the 4 sources of sound energy?
- Acoustic Instruments. •••
- Electronic Instruments. Electrical vibrations are the starting point of sounds from electronic organs and synthesizers. ...
- Living Things. Animals and people make sounds with their vocal cords, their mouths and other body parts. ...
- Machines. ...
- Nature.
How do humans produce sound?
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.
What is sound and how it is produced?
Sound is defined as vibrations that travel through air or another medium as an audible mechanical wave. It is produced from a vibrating body . The vibrating body causes the medium (water, air etc.) around it to vibrate these producing sounds. Sound Produced by Vibration of Objects.
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.
What are the examples of soft sounds?
| Bell call bell in office or home | Clock clock movement | Wind wind blowing sound | Motor motor speed sound | Fan fan rotation sound |
|---|
What type of wave is sound?
These particle-to-particle, mechanical vibrations of sound conductance qualify sound waves as mechanical waves . Sound energy, or energy associated with the vibrations created by a vibrating source, requires a medium to travel, which makes sound energy a mechanical wave.
