Question

What is sound and how is it produced?​

Answer 1

Sound is a form of energy which is produced by vibration of objects. Vibrations are rapid to and fro motion of an object. When a body vibrates, a disturbance is created in the medium by the particles. This disturbance travels in the form of waves. This produces sound.

Answer 2

Sound is created when something vibrates and sends waves of energy (vibration) into our ears. The vibrations travel through the air or another medium (solid, liquid or gas) to the ear. The stronger the vibrations, the louder the sound. Sounds are fainter the further you get from the sound source.

Sound is produced when an object vibrates, creating a pressure wave. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium.
