Difference Between Sound and Noise

Sounds and noises are terms that we often encounter in our daily lives. While they may seem similar, they have distinct characteristics and effects. In this article, we will explore the differences between sound and noise, their examples, uses, and more.

What is Sound?

Sound is a form of energy that results from vibrations or disturbances in the air, water, or any other medium. It is a mechanical wave that travels through these mediums in the form of compressions and rarefactions.

Examples of Noise:

  • Honking of car horns
  • Construction site machinery
  • Thunderstorms

Uses of Noise:

  • Masking unwanted sounds
  • Alarms and alerts
  • Experimental research
