Sound has a very important role in social development.during earlier times when people doesnot know how to communicate they cannot share their ideas and was left as hunters and gatherers .social development means the development or the progress of our society .now when we know to speak ,communicate with each others we can ask we can tell that means we can share our ideas which can lead to discovery of a new idea.hence when we will come to know about new ideas through communication then only we can progress.

hence sound plays an important role in social development.
