What are the Characteristics of Sound define them

Characteristics of Sound

 

 

The characteristic properties of sound by which we can distinguish between noise and music, shrill and grave sounds or sound of men and women are known as characteristics of sound. The properties of sound are given below:

 

Loudness:

 

Loudness is the magnitude of auditory sensation produce by sound.

Intensity can be defined as the energy carried by the sound waves through a unit area placed perpendicular to the direction of waver per second.

 

 

Factors Effecting Loudness of Sound:

 

Loudness depends on following factors:

– Area of Vibration of Body: Greater will be the surface area more will be the loudness.

– Amplitude of Motion of Vibrating Object: Greater will be the amplitude, more will be the loudness.

– Density of Medium: Loudness is directly proportional to the density of medium.

– Motion and Direction: If source of sound is moving towards the listener loudness will be greater or if wind supports the velocity of sound the loudness will be greater.

 

Note: It is about the weak ability of the student, and then the student to study. And let this reason not be so often (that fortunately), but the problem really exists. There are no such people who would equally successfully learn information from any field of knowledge. And not everyone can equally successfully learn by the same scheme, for someone, for example, traditional methods of learning do not work at all, an individual approach is required. But the education system works only one scheme, it will not ask about who wants to learn, who can do this, and who else. A good option is educational video courses that can be found in almost any subject, in any field and in general for any taste and color. The Internet is flooded with all sorts of video lessons, from make-up to the master class for making boats. But not everyone knows that there is also a huge amount of material on educational subjects, and also tutoring through Skype is spreading more and more. So if you are unable to learn by the classical scheme, you can always find the right option.
