Production of sound

Production of sound

In your daily life you hear different sounds from different sources. But have you ever thought how sound is produced? To understand the production of sound, let us do some activities.

When you strike the tuning fork on the rubber pad, it starts vibrating. That’s what you feel with your fingers. These vibrations cause the nearby molecules to vibrate.

From the above activities we see that vibrations are produced when some mechanical work is done. Vibration is nothing but to and fro movement of a particle. Thus, mechanical energy vibrates an object and when these vibrations reach our ear we hear the sound. At the end of this chapter, we will study how our ear senses sound.
