There are several important factors which affect the propagation of sound: geometric spreading, atmospheric effects, and surface effects . These are discussed separately below. This refers to the spreading of sound energy as a result of the expansion of the wavefronts.
What are the 2 factors of sound?
- The Density of Medium: Sound requires a medium to travel. The density of the medium is among the factors which affect the speed of sound. ...
- The Temperature of The Medium: Higher the temperature, the higher is the speed of sound in the medium.
What are 4 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.
What are the factors on which sound depends?
- Density of the medium-the speed of sound is inversely proportional to the density of the medium.
- Humidity of the medium-More humid the air is,greater is the speed of sound.
- Temperature of the medium-The speed of sound is directly prop.
What are the factors of sound?
- 2) Effects of Temperature: Since the velocity of sound in gas, ...
- 3) Effect of Density: At constant pressure, ...
- Effect of humidity: ...
- Effect of Wind: ...
- Effect of frequency wave length & amplitude:
What are the 5 characteristics of sound?
There are five main characteristics of sound waves: wavelength, amplitude, frequency, time period, and velocity .
Does sound travel in vacuum?
Sound does not travel at all in space . The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. ... Radio is a form of electromagnetic radiation just like light and can therefore travel through the vacuum of space just fine.
Why do sounds Cannot travel in vacuum?
Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate .
How we can reduce sound pollution?
- Turn off Appliances at Home and offices. ...
- Shut the Door when using noisy Machines. ...
- Use Earplugs. ...
- Lower the volume. ...
- Stay away from Noisy area. ...
- Follow the Limits of Noise level. ...
- Control Noise level near sensitive areas. ...
- Go Green by planning trees.
What is the speed of sound in steel?

What are the main uses of sound energy?
- Cellular Telephone.
- Motion Picture.
- Telephone.
- C.D.'s Televisions.
- Phonographs.
- Electronics.
- Hearing Aids.
- Video Tape Recorders.
How do we use sound in everyday life?
It helps us to communicate with others . By sound, we can understand the context of the words spoken. Sound can help people to protect themselves from danger such as the sound or horn of the train and other vehicles warn people to give way etc. Sound is a medium of entertainment.
What is the function of sound energy?
Sound energy is the physical vibration waves that travel through the air to reach the ears signaling the brain to interpret incoming sound(s) .
What are the two factors affecting the loudness of sound?
The loudness of a sound depends on the amplitude of the wave . The loudness of sound is proportional to the square of the amplitude. The loudness of sound also depends on the sensitivity of the human ear. Note: Loudness is the measure of how strong a sound wave is at the place.
Which two factors are responsible for speed of sound?
Two main factors affect the speed of sound: the material that makes up the medium—such as air or water—and the temperature . If we know the medium and the temperature, however, we can predict the speed of sound.
What does speed of sound depends on?
The speed of sound varies greatly depending upon the medium it is traveling through. The speed of sound in a medium is determined by a combination of the medium's rigidity (or compressibility in gases) and its density . The more rigid (or less compressible) the medium, the faster the speed of sound.
